Title: Andy's Amati Riva Aquarama build
Post by: Taranis on June 29, 2020, 11:23:35 am
Yes sorry yet another Riva  {-)  inspired by those builds on the forum already thank you.
Build resource link https://www.youtube.com/c/BacktoHardware/videos

Kit has been posted this morning from CMB and I must recommend paying £10 for the CMB membership. The 5% discount on just the kit alone more than paid for membership.
FYI as David said in his build thread all fittings come with the kit despite the fittings also being marketed as a separate pack too.


The etched brass set is extra and will be on a future order.

Welcome the Aquarama owners club..! (1/10 section...)


Excellent choice..! Looking forward to seeing progress.


Heading off to clear up my bench so it looks more like yours....

Thank you for the welcome but you do of course realise it's all your fault that I'm doing this  {-)  Nice to be part of a club  :-))


Judging by the photos of CMB stockroom they sell a lot of these.


My bench won't be like that for long  %%

Interesting product brought to my attention via member ukmike.

I was first aware of this product due to needing to service and fault find an Eberspacher heater many years ago now.
Never a more unconnected subject matter

I've chosen the motors also from overlander mainly due to Turnigy being no stock everywhere.
I've gone a size below David @ 2836 and hope to connect these in a direct line with the shafts.
On 3s these will stay within the 15,000rpm limit of my prop shafts.

Post by: DJW on July 01, 2020, 08:25:58 am
Morning Andy


Nice choice on the motors, I've powered my similar Overlander 3035 units up and can't imagine the boat will need the full range of their output, so I think the 2836s will be spot on.


I'll be really interested when you receive the kit what the etched sheet looks like, and what all this about a separate etched 'kit' refers to. My kit is 6 months old and seems to have the full set of etched parts included. This is what I have:

Thanks Dave
I'm still waiting for my parcel. UPS tracking is absolutely rubbish. I stayed in all day yesterday because it said and still says now that delivery will be 30th June 10:45 to 14:45.
No news today yet  >>:-( >>:-(


I will most likely use the Quicrun 30 amp ESC as I already bought 2 spare last week.

This is the old etched brass which was two sheets and part F-09 is no longer included for some reason. I think it was meant to be part of the steering wheel.

The planking and all the ply is excellent quality. The planking in particular would shame Billings.


Progress using both slow and fast CA for the framework.

This will be good - I'll be following the progress and good luck I love these boats
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on July 02, 2020, 11:33:23 pm
I hope so Mark  :-)


Firstly I've ordered the Raboesch sealed waterproof shafts with bearings that can handle 15,000 rpm max and require no lubrication. I ordered 290mm long 4mm as these can be shortened as required.
Also ordered Raboesch 35mm type C 3 blade propellers L & R handed


So after a full morning of chores I got started this afternoon. All was going well until I came to fit the floor panels then I realised I had assembled frame four and its four additional pieces the wrong way around. NOTE that frame is the only one that is not symmetrical and it caught me out.
I managed to get it out with about 30minutes of effort without breaking it. As the four sub pieces could not be removed without destruction I opted to remodel the frame which was a good fix.
Then onwards with no further problems.
I bought a supply of Aliphatic resin and other bits from Leeds model shop this morning. So like ukmike I use CA and aliphatic as I deem appropriate.
See here the forward floor is the wrong way around.
(https://photos.smugmug.com/Amati-Riva-Aquarama/i-xPpDvsD/0/c1e26c5e/XL/E506A20C-4FA2-459C-ADF6-9CD05CEAAD01-XL.jpg)


More progress after the fix
Now starting to remove material to reduce weight as I progress. I think by tomorrow eve it should be ready to start planking the lower hull.

Morning Andy


That's quick work..!!!  Took me four months to start the planking...  You'll be there in four days..!


The asymmetric cabin layout issue, I can fully understand that oversight, made it myself...


The Aquarama seems to me quite a dense build in terms of where the hardware (motors / Lipos / RC) goes, its all in the most narrow section of the shapely hull. But still there's a lot of structure in the bow section, I suggest looking at weight saving there too. If you look at the videos of 1/10th Aquarama hulls in action, they can have issues with the bow digging in.


And @MarkT...  I think we need one more Aquarama build thread...  You need an Aquarama in your life...

Thanks David but I do have the benefit of yours and ukmike’s groundwork to speed my journey  :-))


No worries about weight I fully understood the numerous mentions  {-)  I will be working forwards with my collection of hole saws today O0

Post by: Taranis on July 03, 2020, 01:49:58 pm
I must post now and have a break or there'll be too much in one post later.
Firstly another part with the potential to get it wrong.
These are made up of four parts, two are thin and too are thick (subtle difference) You must use one of each for both!
(https://photos.smugmug.com/Amati-Riva-Aquarama/i-rswvH4K/0/0eed4451/XL/34279EAA-3E55-43AC-AF0C-275075603693-XL.jpg)

Initially it can be perplexing how to assemble this jigsaw. First I dry fitted all parts and marked their outlines on the transom to help when gluing.
(https://photos.smugmug.com/Amati-Riva-Aquarama/i-7XSccqT/0/0e46cd4a/XL/32EE3DAD-2B79-4676-8936-783D2C4F0373-XL.jpg)


I then glued these parts as shown being careful that the mating surfaces are all in contact and square

Then glued them in place

Aliphatic resin only takes about 10 mins to grab

I then checked the cross member and clamped while the other parts were secure

Removed and glue applied  for final fit. The bottom pieces need the keel filing to get the required fit.

So round two today. Great instructions so nothing untoward and all parts fit well. If it doesn't fit its either wrong way around or the wrong part  {-)

Tomorrow will be more holes sanding and finishing resin all over (first coat of diluted)


The planks are the best quality I've experienced. I think the issue Mike had 8 yrs ago of different thicknesses has been resolved.

Actually Joe planking may be delayed as I'm waiting for Motors mounts propshafts and propellers. I much prefer to have the motors mounted in perfect alignment beforehand.

So far it’s probably the easiest kit I’ve built and not even needing a slipway to build it.
Instructions are excellent and all parts fit.
The planking however is tedious and requires a bit of experience or a bucket of confidence
At least we have the first layer for practice  %%


However building off plan like Mike, is a whole different level  8)

ok i fully understand your thoughts on getting it lighter my worry would be that it could very well twist under power,yes you might not be able to twist the hull yourself on the bench but torsional twisting stress is a total different animal....just a thought.


What are you using to drill the holes with as they are very clean.


Keep up the good work

Shouldn't be a problem Dave once the hull is planked. That will give the hull more strength than it needs  :-))

I don't always follow the instructions if I think there's a preferable alternative.
So I'm planking the stern today and it will not impact on the mahogany top coat.


Some more holes added too

A question for other builders.


Did you fit this part square in its laser cut frame recess or did you apply some angling to it.
I'm thinking I should leave this until the fitted planking is approaching it.

Hi Andy


I dont see any problems planking the stern out of order, and wishing I'd drilled it out now too...


The dock light enclosure needs to wait i think, the lime planks will give you the angle and depth that they need to be at in the frame. I've not used them as I plan to use the aftermarket Cap Marquette chrome versions.

Ah. Yes. Most of the cap marquette parts seem to be duplicated in the included Amati kit, but some like the docking lights are of interest. I think CMB carry the range but there are stock level issues.


I've a folder on my desktop with some useful links to the parts I've found. I'll post on Monday in case they're of interest.

Overlander motors arrived followed by varnish. Only just started sanding a couple of hours ago due to other jobs. The wife spilled red wine all over our van cab floor last year and I've been putting off fixing it but as holiday time is due it had to be done.
I kept a template for the carpet after fitting the original but I managed to cut it the wrong way around so had to do it twice  {-) {-) {-)
Job done

Morning Andy


Build looks to be coming on very nicely.


That's a great video too.  That should be the riding attitude we aspire to for our builds, flatter spray off the bow.  Are you going to make any mods to the chine, or rely on weight saving to get lift..?


It'll be red trim for me.   :-))


David.



Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on July 07, 2020, 11:25:23 am
Thank you both
Regarding a chine, what I have in my mind is the side planking protruding below the bottom planking. The real deal seems to do this in pictures I've seen.
As the side plank may be vulnerable I envisage fitting a square mahogany bead on its inside edge before shaping it to taper away at bow and stern.


After Spineys reply today I'm going to remove yet more weight. I have not brought the Proxxon / dremmel into play yet  {-)

I hope the pictures help other builders as its very difficult to decide where to sand to initially but it takes shape over a few hours of careful effort.
I'm about 95% happy to this stage and will fettle anything I spot over the coming days.


This is my interpretation.

So I decided to fit the first 5 planks per side to approach the prop tube openings.
For Barrie the pin pusher is fine once you learn the easiest way to pick up fine pins is to lick your finger tip and dab them up  :-))


I use small clamps to prevent any undulation in side by side planks

This is a thoroughly enjoyable build to follow, I look forward to seeing and reading of your progress each day. The photo's are of such  good quality and should I ever pluck up courage enough to attempt this kit they will be invaluable.
I have built a couple of models from scratch, quite hard going and your last photo fairing the frames brings back panic memories of out of line frames and  chamfers wondering if I would ever get the planks fixed!.

Tool update. Mark T put me onto this well over 2 yrs back now and its had lots of use but I finally got fed up of it falling to pieces. The countersunk hole and screw for the pressure plate is pathetically poor in design and the screw slips out.
Tonight was the final straw and I fitted a washer to the screw but also applied loctite to the adjustment threads.


CURED!

I'm now at the stage of working out the drive train. I don't anticipate shortening the Raboesch prop shafts I bought but I've ordered new couplings in solid brass like I use in my Shannons.
The wooden frame in the kit for the Amati drive set I've re purposed to aid aligning my shafts. This will be moved rearwards until I'm happy with the prop position.
Tomorrow I'll build a bed for the motor mounts while correctly aligned.

Now this looks like the work of someone who's done planking before....  Very nice start.  I like that square section on the keel to give a clean edge to plank to.


But a little surprised that motor mount doesn't have more large holes in it.  Doesn't look like it belongs somehow...

Top tip to cut down on sanding. The high spots that seem to take forever with sandpaper are sorted much easier by drawing a utility blade along it. Well know to cabinet makers  :-))

Yes constantly but pins are only on the frames. Without clamps in between frames there will be undulation in side by side planks.
If you look closely Nord you will see nails, these are removed as the glue gets a grip.

Ok,  I get it. I can see them on that first plank. I could have really done with that tool when I was double diagonal planking my RAF Sea Tender made harder because I couldn't see the frames on the second layer.
Do you just push the pin in thru the plank with this tool ?

Yes Nord. There is no accuracy with these tools but not necessary here as the frames are very much wider than the tool and the pins are temporary unlike with 18th century ship builds where the pins might be driven fully home and left in.


On the mahogany top skin I hope to use no pins at all.

Looking good Andy !  the Amati kit builds into a great model (another on my extensive bucket list).

Liking the swiss cheese technique - Amati's self jigging construction involves lots of timber to keep the initial framework square,
when double skinned the hull will be rock solid and you may be able to remove even more, especially if you are glass skinning inside and out ?

Regarding the above clamps issue - a life long aeromodeller I've tried every clamp, jig and pin on the planet.
I've recently discovered plastic soft grip pegs and highly recommend them -
strong enough to hold items - but importantly won't dig into wood - ideal for model aircraft balsa structures etc,
easily squeezed open without requiring fingers like Arnie Schwarz. and £1.80 for 12 from the hardware shop.

Attached pictures of the packaging highlight the SHM label - beware similar imitations are around and nowhere near as good.

Thanks Paul
Last night I was sat looking at it with my pull saw in hand but thought I'd better not attack it under the influence of Belgian beer  {-)


The inside will be completely covered in finishing resin. The outside mahogany is I believe many coats of varnish.


The tips on the Wolfcraft clamps will come off if they have glue on the clamping face but not break off and can be re attached. . They are designed to swivel so they stay parallel to the surfaces at all thicknesses. When gluing the way I am they stick to the Aliphatic resin but if you swivel the clamps side to side it sheers any glue before squeezing the clamp to remove.
Title: Re: Andy's Amati Riva Aquarama build
Post by: ChrisF on July 11, 2020, 11:19:31 am
That's good to know, because like you I've ordered 30. The tips coming off won't be a problem, with my others (bought from one of the shows so expected better) the pins were breaking off, even before being used sometimes. I've got some of the bigger ones and they are better but they tend to be last resort clamps as I've got better.

It was a good decision not to do anything after partaking of Belgium beer! You're a braver man than me anyway with the number and closeness to each other of many of the holes you have cut. Those hole saws of yours must be good not to break the timber between holes.

Post by: mrzippy on July 11, 2020, 02:55:43 pm
Yes the pegs are great, they have a nice gently smooth spring action, with plenty of grip and soft jaws won't leave an indent - 
might be a tad wider/fatter than Wolf style, the ends could be squared off if required on a bench sander.

With you regarding PULL Saws - I'm annoyed it took 65 years of being on planet earth before discovering them !
great piece of kit, to date I have an Irwin crude plastic handled version, similar to Xacto saw size -
but have tried brother in laws full blown Japanese with wooden, leather bound handles,
and they are incredibly sharp and accurate, but a bit on the big size for table top use.

Re Riva handling, I've read somewhere the full size hulls do not have the usual spray rails etc,
it's perfect straight off Carlo's drawing board with no mods, therefore if the models are to scale and accuarate,
you would think they would perform the same.
I have seen the ARTF ready built versions that were popular around ten years ago, digging in on turns - they're not scale hulls.

A thought - going back to silly fast power boating days, if the model digs in, move the centre of gravity backwards to help lift the bow,
your extensive weight savings bound to help in lowering the hulls cg., it may also need moving backwards a tad ?
worth bearing in mind while you've got your pull saw to hand - is there plenty of room to move the lipo's etc backwards.

My offshore racer struggled in the turns, to the extent of barrel rolling sideways, moving all the essentials back as far as possible
made a huge difference to handling, may of even added a chunk of lead at the transom.

All the handling and weight problems are well covered in ukmike's Amati Riva build hence why we are all making weight reductions throughout but main concern is the bow. The boat rides low at the front at slow speed if not enough timber is removed.
All the running gear is in the rear half after the motors  O0


32 planks now fitted. 34 left to play with so looks like a few spare I'd say. I reckon about 20 to finish the sides and then there's only the foredeck to do.

I am also a convert to Japanese pull saws.  You can get small ones that can be used for modelling, like this (https://www.axminstertools.com/japanese-small-dozuki-tenon-saw-110048).

I don't think an accurate scale model will automatically perform like the full size.  After all, water doesn't scale, its density, surface tension and so on stay the same whatever thesize of hull moving through it.  Scale Rivas have often had handling problems in the turn, and I think the hull form simply doesn't scale down particularly well.  Having said that I have no idea of the weight, centre of gravity, power to weight and so on of those models, so even if the hull shape is accurate other factors could be killing the model's performance.  It will be interesting to see how Andy's aggressive weight saving affects the handling.

don't think you've seen this Andy - it's another half finished symphony, one and a half times Aerokits 'Sea Hornet'.

Built as an experiment to see how well timber and white plastic planking works under epoxy finishes etc,
before committing to the likes of a Riva etc, poor old girl never did get flatted and polished -
West Systems and fine glass cloth (disappears) on the deck and didn't split or crack as expected.

Title: Re: Andy's Amati Riva Aquarama build
Post by: SailorGreg on July 16, 2020, 02:53:01 pm
My Dumas Chris Craft has a similar unsupported overhang of the prop tube at a slightly steeper angle than yours.  The kit instructions suggested gluing a triangle of wood in to support that overhang but I didn't and I've run the boat regularly for several years now without any ill effects.

(https://modelboatmayhemimages.co.uk/images/2020/07/16/prop-overhang.jpg)

Just out of interest, are the holes left by the pins in the planking any bother?  I have always shied away from doing something similar as I felt you could end up with a finish with measles.  Although I guess as there is a second planking to come, holes don't matter too much at the moment.

And hurry up - I expected you to be finished by now!   {-)

Title: Re: Andy's Amati Riva Aquarama build
Post by: DJW on July 16, 2020, 03:05:47 pm
Hi Andy


My view is the shallower the shaft angle the better for the 1/10 version. They seem to dig in at the bow with a build that follows the plans. I think the steep angle lifts the stern, contributing to the bow digging in issues...


Also, the full size boat has two big V8s under the sundeck and the fuel tanks right at the stern, so my guess would be that the full size boat has most of its weight further aft than the models. Upshot is the steeper angle helps lift the stern on the full size boats.


Just my opinion.
Best regards
David.

Thank you for the support you two  :-))


Yes Greg all the nails on the first skin can be ignored. Holes in the mahogany I feel benefit from the extra fine nails I am using. I believe Mike applies soapy water that helps the holes disappear. Amati suggest mahogany sanding dust and adhesive. I'll see when I get that far.


Some items in the instructions show the use of nails where it's simply not necessary.
Example
(https://photos.smugmug.com/Amati-Riva-Aquarama/i-fDf7pt6/0/e6b42522/XL/39D3F5D7-948D-49C4-B1FE-D8CBE3C6EFF4-XL.jpg)


These parts should not be glued as per instructions as they are too long.
(https://photos.smugmug.com/Amati-Riva-Aquarama/i-qGPMLCf/0/014ac4bb/XL/16E27324-7946-4BA9-832B-5AA618BEE576-XL.jpg)

Better to trim it down to length before gluing

Post by: Taranis on July 16, 2020, 10:00:53 pm
Thanks to an update from Mike I can be assured that by using the very fine brass pins that wetting the wood before sanding will make the holes disappear for the most part. The nails in the kit are quite THICK, I have not even opened the packet. I bought the thinnest 0.5mm from CMB. To members that's £1.56 per 100, I re use as many as possibly but some will be so badly bent they get binned. I ordered 200
Hope that helps  :-))
Title: Re: Andy's Amati Riva Aquarama build
Post by: DJW on July 17, 2020, 08:20:04 am
Agreed about the Amati supplied pins being too thick, I found too many were also of varying length, a few blunt tips and a few with heads that didn't fit the pin pusher...  I'm also going with the finer 0.5mm versions for the mahogany layer.


I'm thinking that the 'swiss cheese' technique of boat building also allows better access to the inside of the lime layer, and this will allow use of the little rare earth magnets to keep the planks tight / flush in place of clamps.
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on July 17, 2020, 08:22:40 am
Magnets occurred to me also  :-))  but certainly it makes it easier to coat the inside of the planking with resin.

Good to know Stan, as recommended by ukmike  :-))


Reached the point of making decisions regarding the bow spot lights.
I've opted to start by sanding a taper into the housings.

Position and angle is pretty much up to the builders eye.


I've left enough wood that they still need sanding back for the planks

Earlier I alluded to using stock brass rudders and remodelling them to suit.


These are size large and have just enough thread length to fit the model.

Hope you do David I'm getting David's Amati Riva build withdrawal symptoms  {-)   :-))


I made a decision here as something has changed since these photographs. According to them it only takes 6 side planks to reach the bow peak. On mine it took 7 so I say they were originally 8mm planks and now 7mm.


(https://photos.smugmug.com/Amati-Riva-Aquarama/i-kXBkSH3/0/89df6a1d/XL/644345B5-4137-416E-A60A-7B51DBCDBF45-XL.jpg)

Anyway even then the builder ended up with these silly slivers of plank on the top edge.

I decided to use some square strips I had in stock to avoid those by fitting with 2 planks to go.

This way I finish on a full plank that I can trim back

I found the best method to remove the high spots was a small block of wood and P120 grit.

Sanding side to side across the grain works very well in the concave areas.

A modification to the bench seat. I found this was a fiddle to put in place without it falling through so I've added supports to both ends that now prevents this happening. I may yet remove the existing cross piece.


(https://photos.smugmug.com/Amati-Riva-Aquarama/i-xNWMS5L/0/a123b2fb/X3/6101C02E-DBA8-48A8-813E-670357269D3E-X3.jpg)

I went ahead and removed the bench seat support. This not only reduces weight but improves access especially with Allen keys

It would be very interesting to know the weight of the kit in box when you received it, and the final weight without hardware.
Your progress is impressive, seems to have gone faultlessly and the result so far has a look of quality about it.
The motor couplings interest me.

Looking good Andy.  Good idea re the revised bench supports, think I need them too, as you say the access to the motors is improved too...  And looks like I need to find a big drill for that bench seat itself...


The supplied seats seem rather heavy, just saying...  Any plans..?  I'm thinking to rebuild in balsa then cover in the cream upholstery material. (I think Mike used cork to good effect.)


Best regards
David.

Thanks  :-)
Personally I think the seats are OK and practical and should look the part when painted. I found that mine are not glued together very accurately but managed to separate the parts and re attach with CA. Maybe need a magnetic fixing in the end.


This part I noticed is an unwanted recess so I've filled it in with scrap.

This is now ready to plank but I need to upholster the cabin first.

Hi Andy.


I've done exactly that with the big one and as you say it's as dark as the Black Hole of Calcutta in there, unless you add some form of lighting, which I personally don't do anymore. The louvre doors solve the problem and if you mount them with magnets you can easily get into the front, though why you would want too I don't know, unless there is lots of wiring in there.

Title: Re: Andy's Amati Riva Aquarama build
Post by: ukmike on July 24, 2020, 11:27:39 am
Morning Andy.


Don't know if you noticed this on my Riva blog, but a good way to make sure that the sanding has removed all of the high spots, just scribble all over it with a pencil, the more scribbling the better. Then sand and sand until all the scribbling has gone, then it's done. For a final finish wet the planking with very slightly warm water with a little washing up liquid added. That raises the grain, then finish off with your finest sand paper.
This applies to the mahogany also before Varnishing.
Hope that helps.


Mike

Good afternoon Andy.

I know exactly what you mean about delivery.
I can't do anymore until some bits arrive, but seems always the one that you need most is the last to arrive, even if you did order it first.
I ordered some varnish a week ago and a replacement brush for the vacuum cleaner Wednesday, the brush arrived this morning but no sign of the varnish.

I'm off to the shed now and maybe tidy something !!!

Typical, but not unexpected, could be worse tho', in Italy a letter to the next door neighbour can take up to a week or more, not that it helps our cause at all.
Fustrated or what,  >>:-( >>:-( >>:-(

Busy morning, nice walk into Leeds to the bank in the Sun but the first time I've had to wear a mask to put money in!

Anyway back to it. In case it's not obvious the foredeck needs to be 100% symmetrical for the inlays.
It's normal to plank from centre and alternate left and right but in addition as these are all under a half plank length I was sure to use the same piece for both sides each time. This guards against any planks that might be slightly different widths creating inequality.


Nearly there and I think I will have 4 planks surplus but don't tell Amati !!  {-)

Now there is a thought  O0


I think I have the shape dialled in? However looking at many pictures of Aquaramas I see a noticeable difference in how extreme or not the curves are.
I assume this evolved over time so varies? If I haven't misunderstood this Amati is based on a 1970 model ??


Anyway it is what it is...

Post by: DJW on July 25, 2020, 09:03:32 am
Shape is looking great to me, excellent basis for the next layer. Its going to be tricky to prove the shape is as full size, but I think that as Amati have concentrated on a scale model rather than an RC model, it shoud be close to scale dimensions. And let's face it, it does look the part...!


I really like the smooth progression of the side of the hull from the massive flare at the bow to the reverse curve at the stern.


I think the forward deck has three layers, the lime, a ply panel, then the inlay. I was wondering whats best re weight. Build as normal, or thinned resin on the lime for strength, then cut with ya hole saw, then the panels to provide the flat surface for the inlay...?

I think he swerved all the individual ply skins and fitted one big one  {-)
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on July 25, 2020, 12:24:22 pm
Having now watched that video I see he has fitted ply over the planks. I don't speak Italian so I don't understand what explanation he gave for doing so.
At the end of the day his inlay is not symmetrical and has a tiny tiny slither on Port side compared to Starboard.


I will follow the plan and sand the planks smooth. I will check with a vernier that the distance from the centre mahogany panel to the edge panels is exactly the same both sides.


Now my hot tub is fixed wife is happy and I can continue playing  :-)

Good news that you already have the lipos, and a better weight. And your wife can get a refund on the graphene versions.....


I've started to think that I need to take a slightly different route with my build. I'm thinking of getting the mahogany planks from keel to chine installed. Then install the prop shafts, P brackets, rudder tubes and water pickups while I still have better access from the top.

I have already dry fitted to test everything earlier before completing the skin.

I plan to set my prop tubes in place once the missing special nut F arrives from CMB.
I will plank around them.
The motors and servo are now fitted and easily accessed so I will line everything up, epoxy in place then remove the shafts and props until completion. The rudder tube seats will need cutting in on the sloping hull also.

I find it's easier to make the first pair overly long and then lay the next plank to mark a trimming line. Much easier unless you have two pairs of hands. The rest of the planks are easier here on.
I'm pleased to find that it is precisely 5 planks each side to the side of the 8mm prop tubes. 8mm planks  :-))

Morning Andy


Looks like a very successful weekend...!  FYI I had a great time at the garden centre. Not.


Excellent start to the mahogany planks, keep the tips coming, I'm going to need all the help I can get..!


And I like the magnet solution for the rear hatch, very neat.


Looking forward to todays update.
David.

Here after a good dragging over with a Stanley blade. Currently at 200g plus of Aliphatic used.
At the bow I kept trying to remind myself that it will be hidden anyway but that didn't help. %%


I noted earlier with an amendment that there were 5 lime planks surplus. It doesn't look like there will be any Mahogany over and not all the planks are good. So in line with David's timely post about grading planks into colours grain and quality I'm trying to use up the less than perfect here.

Firstly I'd like to point out that I've never done a second skin before.
Conclusion is it is very much easier  O0  all the hard work is in the preparation of skin one.


(https://photos.smugmug.com/photos/i-2GrgKcg/0/X3/i-2GrgKcg-X3.jpg)


I might be stating the obvious here but I drag a chisel blade along the plank edge before the glue is hard, don't forget!


(https://photos.smugmug.com/photos/i-GwJT6Vb/0/X3/i-GwJT6Vb-X3.jpg)


At this point of fitting what I'm calling the transition plank, there lies the oportunity to adjust if you were not happy with the first layer.
What is more important is that they both look the same. I measured down from the deck in a number of places and made pencil marks before starting to fix them in place.

Post by: Taranis on July 28, 2020, 07:14:59 pm
One more point tonight.
It wasn't too much concern on the first skin but I am being EXTRA careful with the lower edge of these transition planks as they form a spray rail on the forward third of the hull. Most I've seen obliterate this with sanding. If done carefully it is quite significant but won't be strong until varnished. It tapers out from the bow leading edge and back in as it approaches the straight section of hull.

Planking at the bow without a rabbit to guide you is very tricky to keep in a straight line. I reckon you’ve well and truly got that spot on it looks lovely. If you run out of mahogany drop me a PM with your dimensions and I’ll run some through the table saw for you

Thanks Mark and very kind of you  :-)

Yes I know my plane is face down  {-)

This is what I mean about the integral anti spray ridge, very subtle but I think potentially very important. I will sand this to exaggerate it further. This is not highlighted in the manual.

Morning Andy


Looking very good..!  And absolutely agree about the shape of the chine at the bow and the fact that it needs exaggerating a shade.  It needs to keep a really sharp edge and be big enough to separate the water coming off the V bow from sticking to the hull and continuing up.  As seen on too many YouTube videos...


Are you undercutting the planks to get them tight..?  And if you are are you using a machine or plane..?


Wish I understood what was being said in that Video 38...


And I won't mention the plane / table thing. Ooops, I mentioned it...


Have a good day.
David.
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on July 29, 2020, 09:21:20 am
Good morning David
So far no undercutting necessary and any tiny gaps will fill with varnish
No need to be so neat at the bow either as it is all hidden or painted in the end but just got personal pleasure and skill practice from doing our best as I’m sure you will also.
No sanding yet so it should come alive when I do
I’m going to varnish the belly as soon as I’ve done that.


I've noticed that the piece of wood supplied to me for the rubbing strakes isn't mahogany. I think it's Walnut.

Hi Andy

Don't rely on the tiny gaps being  filled by the varnish, not unless they happen to be microscopic, which you wouldn't see anyway.

Sorry.

They are the worst of colours and wavyness, likely be painted in the end.  Just waiting for a missing part then I'll connect everything up and resin the shafts in.  :-)


The first coat is very quickly soaking in.

While I remember I'll rewind to this detail. I decided this arrowed is a weak spot despite having another skin to go on.
I used heavy gauge 25mm wide glass cloth and resin on the inside to reinforce. Also means there is no chance of sanding through so can round off as much as is pleasing to the eye.

I've just tested everything for fit with the batteries and made this ESC platform from the mass of leftover ply.
Also coated all the recent additions in dilute finishing resin.
The on/off switches for the ESC's will sit on the bed between the battery locations.

The grain confuses the camera but I've tried to capture it.


This is square Amati Walnut planed to a triangle glued flat to the hull bottom then planed along the side to flush it off. As the hull V gets steeper stern to bow the resulting chine has a nice gradual taper when flushed with the hull side. Aliphatic had no problem gluing to the sanded varnish.

The various Riva posts reminded me I'm sure I saw one before.  I think there was one at "Classic Remise" when I was in Berlin Autumn 2012.    Your comment on the chine spray rail seems obvious enough here.

...It was in museum condition, no doubt dusted with an ostrich feather every day -same as most of the cars there not stored in the glass cases.

Not sure if this pic helps you or any of the other builders. Strangely I only took one photo for some reason -probably more interested in the tens of millions of pounds worth of cars surrounding it!  It was somewhat "out of place".

Over the years there were several models in various shapes. My build is a 1970 Aquarama and the bow especially differs from others. On mine the spray rail crosses the water line and terminates much higher up the bow.

Ah yes you are right. And there is much more flair at the bow on your design. The one at Remise looks shorter also unless it's perspective. Pass the pic on if it's any use or inspiration though.  The colours are nice if nothing else.


Re: earlier post about the Riva in the barn -they probably cost a significant chunk of cash to store and run every year compared to buying.  You know what boat in real life stands for don't you?...

...I shudder to think how much that one cost to store at remise.  The depot is used by oil sheks to store their "spare" toy lamborghinis and Ferraris in for that one or two days they happen to visit the city.  Saves cost of air transport each time apparently!

Title: Re: Andy's Amati Riva Aquarama build PIN PUSHER TIP
Post by: Taranis on August 02, 2020, 12:02:18 pm
When I first bought this Amati pin pusher I was asked how I got on with it. The placement of the nail did not need to be accurate for our purposes BUT I have found that with 0.5mm pins that probably 1 in 3 bend or won't penetrate.


I find myself running short of nails despite probably ordering 400 at this point  %%  They are cheap tho.


So I've adopted a new approach that has solved the problem completely.


Pre drill as you go with .5 drill bit. This might seem a bit of a faff but in practice it is quicker.

As I approach fitting deck skins this is a good time to raise a question for other builders.
The manual skates around showing a picture of how this should look but construction steps lead you to this as pictured. I feel that the mismatch of levels should be sanded out.

I've always found pins to be a proper pain and they also leave a hole in the wood which sometimes stands out.  I gave up on them to be honest and just used clamps on the second planking.  Its less fiddly and no holes - I don't know if you found the same but I also found the pin pushers to be less than useless.  Lovely job on the second planking BTW this should be another special build when complete.

Post by: Taranis on August 02, 2020, 01:18:47 pm
Thanks Mark
The .5mm holes will disappear if following Mike's tip of wetting with soapy water as it expands the wood and raises the grain. I allow to dry before sanding.


This hull has places where clamps are just not possible especially around the bow as they cannot grip and slide off.

The styrene strip in the kit will just about hide the deviant. Nothing I can do about the grains
Title: Re: Andy's Amati Riva Aquarama build
Post by: DJW on August 04, 2020, 09:09:13 am
Morning Andy


Just catching up...


The mismatched grain irritated me too, but I'd only seen it in the cabin foot well sides, some vertical and some horizontal grain.  Not really seen, so not a big problem, pity they've done same where it matters on the deck.


Re the stern ply to plank issue. If the trim can cover, that's got to be best option as it's least risk I'd have thought.  Another approach would be to use some ply offcut and set it into the problem area, and blend it... Big risk though as that ply can't take much blending or the light ply layer is exposed.


Not sure about that forward to side deck join either as I'm not at that point. I'd look at dry fitting the remaining parts in that area and see if it gets covered, whether it matters...


Best regards
David.
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 04, 2020, 09:21:27 am
Hi David I did think about inlaying a strip but that I think would be a bigger risk as the deck ply is so thin as you said. The forward deck joint is very missmatched and on show so all one can do is make the best job of it as possible. I suspect after 10 coats of varnish the eye wont be drawn to them  {-)


I'm not happy with the styrene strip as a trim and will be looking for an alternative solution.
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 04, 2020, 09:52:54 am
BTW FYI I'm almost finished planking and can confirm there is JUST enough, no spare! So be very careful to save the best pieces for where they are most important and use the crappy ones on the bottom.

I thought I'd turn to the rear hatch and decided that the two ply uprights needed filing or sanding flush.

The next part involved fitting mahogany side pieces but I immediately noticed that 8mm plank is not wide enough alone to leave enough material proud so thinking ahead of perhaps a vinyl strip in the centre I loose fitted a piece to act as a spacer before fixing the mahogany strips.

Hi Andy I don’t think you’re issues are that bad really. The stern planking doesn’t look like it’s been bevelled so the more you sand the greater the gap becomes. Rub some PVA into the joint and sand it straight away while it’s wet. I reckon the small gap will disappear as that’s what I did. As for the ply I’d airbrush that mate. No one will ever know as it’s such a tiny area. Keep going it’ll be amazing  :-))

Post by: Taranis on August 04, 2020, 07:26:39 pm
No that's just unsanded because to sand any more off the ply to achieve the same level would reveal more white making it worse. That line will be covered with a trim eventually.  :-))

Good morning David. Last night I discovered there is not enough lime inlay by about 7 lengths.
At this point I have 9 mahogany strips and 2 lime in bits. I don't think I need 7 lengths but I do know I won't have enough.


This is either an Amati error or they have measured it in metres rather than number of strips. I certainly would not want to be joining scraps together to make up lengths required.
Best check what you have in your kit so you can get sorted.

I can get out of this hole because I found I have in stock some 1mmx5mm lime strip that I can split down the middle for the last few bits.

Thanks Mark. Just for effect but nothing like varnish will do, a wipe over with isopropanol

I don't know if I said this earlier? but I never fancied this model one bit from pictures of finished examples.
Another forum member sewed a seed in my ear and having looked at other builds on here UkMike and David's it just roused the desire in me too.
Value for money in kit contents 10
Value of enjoyment 10
About 250 hrs spent so far as a retiree so expect a year part time to complete this so even more value.


EDIT I just hope it sails without catching fire  {-)


Maybe time for another all up weigh in tomorrow  :-))

Having made note of Mike's recommendation for these parts I have concluded that the parts supplied in three pieces in the current kit are not suitable to mount atop of the Sax boards the two cleat parts have a flat slab side made to suit the kit assembly instructions rather than a tapered edge.


Still I find that if fitted as per the manual they will sit too low and thus require too much material to be taken off the sax boards.


My personal solution is to fit a spacer beneath as a compromise, the sax boards will then be carefully mitred so the musetto looks like it is on top.


I began by filing the mating surfaces of the three parts before using CA so secure them as one.
I then marked the deck outline for the spacer

I'm looking at the styrene strip supplied for trim. I'd prefer a better option but so far fruitless.
Anyway assuming I end up painting this chrome the other issue was how to fix it.
As a trial I have bought stainless steel pins .59mm shaft and countersunk the pre drilled hole with the tip of a 2mm drill bit.

You've made that difficult task look very easy and they fit so well.  Why not make your own half round trim?  Get a piece of mahogany which is square and then make a scraper out of an old hacksaw blade to the required shape.  You only need a Dremel to do this and its quite easy with this wood.  You could do this as you more than have the skills.

Hi Andy, I have used something like this  (https://www.ebay.co.uk/itm/Chrome-Detail-Styling-Self-Adhesive-Strip-Car-Edging-Moulding-Trim-3-5mm-x-3-65m/324206568964?hash=item4b7c37a604:g:n6AAAOSw1Fhe8Mwa)on a couple of my boats and it works well - stays stuck for a long time (so far!) and a much better chrome finish than any paint.


Lovely work on the Riva. I suspect sales of this kit have boomed.  You should be on commission!

Glenn at CMB said they do sell out fast on these already. I envisage a price hike  %%  but not while Italy is on holiday  {-)

Personally the two other builds of ukmike and David made my mind up to buy one in the first place  O0

Meanwhile I tried the bow plates and only a little sanding of the hull required to close the tiny gap indicated.


I plan to attach with adhesive at the very end and use dummy screw heads.
Note there is a towing eye on these parts.

Someone on Facebook said I should drill all the holes before varnishing.
Nod approvingly then do it your own way  O0


Personally I disagree with their direction especially as possibly 10 coats are involved.


Surely the wood gets harder after varnishing and is less likely to splinter when drilling it. It's not like I haven't drilled a few already  {-)
I imagine drilling all the holes with perhaps two coats to go and this is my intention.

So I thought I'd fit a prop shaft today, only the one because I'm still missing a part from the other.




The brass couplings I bought in this instance were too slack and too short to guarantee perfect alignment. SCRAPPED that idea.
I had an alignment coupling from a previous build that is same length as a Huco assembly at 44mm and it just fits. I had to drill it through full length on the lathe to 4mm and this will be a permanent fixture. Another one ordered from model boat bits!


Working backwards this is my finished product with 2mm blade clearance. There is no way that a bigger than 35mm prop would ever be considered BUT there lies the possibility of reducing to 30mm if necessary so I kept it tight.

Due to the current high temperatures my varnish was ready for a rub over with scotchbrite red. I'm avoiding sandpaper as much as possible.


All is fine but I'll varnish it tomorrow.

Any technical reason why you kept the clearance between propellor and hull so small at 2mm?
I hardly ever give this dimension any thought when I'm building, mind you I not able to build with such quality as yourself.

Yes Nord thank you
To keep the prop shaft at the shallowest angle possible for pushing without lifting the stern or ploughing the bow

Post by: DJW on August 13, 2020, 09:30:20 am
I really like that chrome edge trim, way better than the Amati supplied solution.


Rest of the boat's not looking bad either..!!  ok2


Making me wish I had more hours in the day to keep up..!


Strongly agree re the shallow shaft angle being important for this hull.


Looking forward to this afternoons update already.  :-))

Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 13, 2020, 10:15:12 am
Good morning David. Yes the trim looks pretty good but you might want to drill it and fit pins for more authenticity? or maybe not  %%


This morning I looked at how to secure the prop tube nearer the motor.
I came up with this simple solution by drilling two 20mm roundels out of the scrap ply and then slotting them 8mm


This simply fits in place with slow CA


Looking at the big picture it reminds me to explain why I have not sealed off the corners of the Sun deck. These corners are the only way for air to vent for cooling. As I said previously I'm not concerned about water splashing in as nothing electrical is at risk. I will likely make a louvred grill in the front of the bench seat like Mike did  :-))

Hi Andy


Agreed re the pins with the trim, that's going to really look the part.


Prop Tube at motor end.  Agreed it needs supporting. I've used a rubber grommet in the frame to give an isolation from the hull (which resonates, a lot), and offer a small degree of alignment correction.


(https://www.modelboatmayhemimages.co.uk/images/2020/06/16/20200616f.jpg)


Then one of the cable protecting tapered pieces that fits into the grommet (not sure what they're called) on the shaft.  This gives a firm grip with a bit of isolation...

Definitely getting varnished today. The scotchbrite reds give a lovely smooth consistent finish and I'm still on the same 1/3 of a sheet having done the whole boat.
I expect it will get darker as I go.

Where did you get the chrome edged d profile strip?

Good morning.
I've just applied a fourth coat to the keel panels. The rest is still on second coat waiting to be matted before coat 3
Yesterday I cleaned the craft room and no more sanding will take place in there from now on.


I've also ordered some Marine no.1 from Brian which will be posted out today.

Nice work on the varnish!  Did I miss something though, or are you going to cut the holes for P or A brackets on the propshafts very carefully later?


Notice you also have the rubber O-ring on the Raboesh rudders outside the hull?  I always thought that for inside the hull.  I put a small brass or nylon washer, if anything outside using these rudders.  Will the O-ring wear away over time as you have it now as it's a hard rudder blade edge against it?  Or was it just there as a spacer for pics so far?



Rich
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 14, 2020, 09:30:04 pm
No P brackets, no point given such a short protrusion and 8mm tubes are stiff enough already.
The rudder blade is against the rudder tube not the O ring and the pressure is governed by the tiller arm so that is user adjustable.
The O ring is on the outside because the locknut is not behind it but another level higher up in the hull.
In the pictures the locknut is not fitted but when it is the O ring will sink into the tapered/countersunk hole.
 :-))


I will make a point of better illustrating this in pictures when I fit them
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 14, 2020, 10:08:08 pm
Hopefully this will explain better Rich.


The locknut and washer are going where arrowed in blue. Here the ply is at 90 degrees to the threaded rudder tube and also why I needed size large rudder so the tube had a long enough thread.


That arrowed red is at an angle to the tube and not suitable or accessible for a nut to tighten evenly.


The countersink on the outside of the hull takes account of the hull skin not being at 90 to the tube and accommodates the O ring when the nut is tightened.

Hi Andy thank goodness you and UK Mike are working through the Riva build its so useful I am at the stage of applying the 1mm ply cover strips however these seem quite a bit different in shape size to fit , unlike the mahogany top sheets that fit perfectly , in fact holding the ply and mahogany together they do not match, am i missing a trick here, should the 1mm ply be cut about to fit it seems odd to get this far with this query as every other component just clicked together spot on have i got abad batch 1mm ply do you think look forward to your view

Post by: Taranis on August 16, 2020, 11:13:14 pm
All the ply is oversize Vic. Just focus on the edges where it is most important like around the stern hatch and work from there. The next parts forwards of there will over lap in the centre so need trimming, focus on the fit around the sundeck edges.

A point that Mike made early on was that small indentations or holes will not be filled in by the varnish so called self levelling  {-)  Self thicknessing perhaps is more accurate. As new layers are added any defects get bigger  %%


Anyway I did some filling in along with the latest round of sanding. The scotchbrite pads are good at matting but NOT flatting!

No work today (mother in-laws birthday bash)


Picking up on a suggestion by Derek in Mike's build I am going to start varnishing in the bathroom. I intend to take off everything that is stored on my island bench and de dust it thoroughly then it is just a short trip across the stair landing to a fully tiled room  :-))


Also I am going to start varnishing the whole assembly in one go. My boat is quite stable siting on three point contacts of prop shafts and about 1"  of keel at the lowest point. So the intention is to do the bottom and turn her over for the rest. The small contact of wet varnish at that spot is of no consequence.


Fortunately we have two toilets so the wife is ok with my plan.  :-)  It is only a 3hr window anyway.

I'm thinking maybe 3 more coats but we'll see.  %%  sanding back seems to get easier as more coats are on. I'm on holidays soon so might just get one more coat in beforehand. Off to Scotland again.


The marine no.1 is ok for small parts but no chance of doing a full coat over in sufficient time. As Mike said Classic is the one  :-))

I imagine this will be common to all kits that the seats are badly glued together. I pulled them apart and reassembled tonight then washed them with a scrubby ready for paint.
I used ZapaGap CA and wiped off excess with kitchen towel before it set.

Late last night I decided it would be a good idea to screw the seats to the bases rather than glue.
So that was done this morning and I'm making the seat bases locate with magnets to the concealed plinths I've made and fitted.

Post by: ukmike on August 26, 2020, 08:18:20 pm
Hi Andy.

I've been giving some thought to the problems that you mentioned earlier, re the varnishing.
 
I can't offer any explanation as to the reason for short drying times that you are experiencing with the varnish, as I am getting at least 20/25 mins. before the brush starts to drag. Maybe, the original recipe has been tweaked somewhat by the German new owners, they have owned the company for about a year now and yours is, "fresh" stock. I will certainly be very disappointed if that proves to be the case.
The Classic that I am using if old stock and that may explain the difference. Fortunate for me if that is the case.

Re. brush marks. Quick drying times will definitely not allow the varnish time to level,only reduced temps. will extend it. Also, "tipping off", could help in this respect.

Forgive me if you already know all this, but the brush angle is very important when tipping off. I don't know your varnishing sequence but just for an example, let's say, bottom and sides first and then top and transom last. When tipping off always hold the brush at an high angle and use the tip only and not loaded with varnish.

In the example, do the bottom, thin coats always, tip off, then varnish one or both side, tip off, then tip off the bottom again, tip off the now varnished sides, tip off the sides again before doing the top etc. Varnish the top and transom, tip off, wait a few minutes, check for runs and sages, tip off to correct. Finally tip off the top etc.
After a minute or two check all over for any faults and you should have enough time to correct.

Sounds complicated but worth the effort to achieve your desired finish. Hope that helps.

Mike.
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 27, 2020, 08:27:15 am
Thank you Mike.
I just had to find out for myself what marine no.1 was like and it is that which didn't have enough brushing time.


The recent coat of classic applied in the bathroom initially looked really good but still there are significant dust particles, certainly not good enough when it comes to a final coat.
Next time I'll try it without the extract fan running as that is obviuously drawing air through the room.


I'm doing no more varnish or sanding for 3 weeks now.

Morning Andy.


I have the same problems with dust particles and the only way is to accept my friends offer of the use of his wet room. Just for the final coat.
I don't mind a little dust up until then as they easily rub level as you have found.
It's strange, but I can't remember it being a problem when I varnished my Amati Aqarama, maybe I just got lucky.
Use the tipping off tho' as it does help, especially with the sneeky runs and sags.


I too am going to leave the Varnishing for while and get on with making the deck fittings which is going to be a long job I think, I tend to scrap more than I keep.

Book says matt white but I think Tamiya FINE white primer works OK.

Thanks Mark. I bought Tamiya light blue and French blue yesterday to try for the upholstery trim but today I have to finally go replace the sump pan on the van. I've put the job off for too long and sods law it will spring a leak on holiday. I'm hoping it goes without a problem and only a couple of hours. The new pan is from Poland eBay and twice the gauge of steel that Fiat use as well as being very much cheaper. I have hydraulic self levelling jacks to lift the 4 ton but its not good getting up and down on my back these days  %%  Combining this with changing the 9 litres of oil and filters, one stone two birds   O0

Mixed news  %%
Contrary to advice from an expert mechanic in the trade I cannot remove the sump without removing the offside drive shaft as it blocks one of the bolts  <*<


Good news is having scrapped off the very substantial rust and tapped the casing all over the affected areas it does not sound like it will fail any time soon so I’ve sent wifey for wire brush,hammerite and paint brush  :kiss:

Title: Re: Andy's Amati Riva Aquarama build P40e mixer
Post by: Taranis on August 29, 2020, 10:37:32 pm
Whilst whiling away time this evening I had a rummage through my Action Electronics stock and found a P40e
If I'm not mistaken this will slow the inboard motor on turns ? even with brushless as it acts on the ECS signals only and not the power to the motors like a P94 for brushed motors does.


So after my jollies I'll set this up as per instructions with 2 spare servos on the bench.


Basically it connects to throttle and rudder RX outputs and mixes 2 ESC's proportional to rudder on the outputs.


I plan on using the mode 1 of the four options available.


It is very lightweight  :-))

Nord.
Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on August 30, 2020, 03:30:44 pm
The rudders can be regarded as one, there is only one servo operating them.
Motors there are two with one esc each


On the P40 there are location points for esc 1 esc 2 and rudder


The two wires marked S and T are Steering and Throttle
They connect to the receiver as aile and throttle
As long as both dip switches are set to on the unit will operate in mode 1


The throttle will operate on left stick as normal but as steering is applied on right stick it will slow or stop the inboard prop

Post by: Nordlys on August 30, 2020, 03:51:04 pm

Hi Andy


Good plan with the P40 I think. I've taken a similar approach but am using tx mixing to get same result. I think its going help reduce the banking seen on a lot of the 1/10 aquarama builds, we shall see.

Hi David
This is same brand but a different model to Stans.
It has four working faces and you rotate the one most appropriate to the front.
These do not get discounted and this is the best price I can find.
There are copies on Banggood but they look like they are cast and plated rather than cnc machined.
Stans 8” is over £80 delivered
The 5.5 is not far behind at 72.95 plus P&P 4.95
If I did battleships like Stan I may have spent more money for the longer models

Hi All


A question on the P40E after setting up and with every thing in neutral, if I apply just left or right rudder I find a motor will start which one depends on which way I move the rudder stick. If I apply throttle forward or reverse then apply rudder then I get the desired effect of inboard motor slowing down.


Mode is throttle left stick. Any help appreciated.


Mike

I don’t know Mike but that would be useful for parking the stern end against the dock by blipping the rudder.

Title: Re: Andy's Amati Riva Aquarama build
Post by: Taranis on September 25, 2020, 08:18:34 am
I can only think that applying rudder without throttle has little to no effect so it's perhaps programmed to apply a little throttle autonomously

Having a clear up today so she got a looking at. The seats etc were spray painted with Tamiya many months ago and this has never set but remained tacky. This must be to do with the material Amati used for these parts.
I spent more than an hour getting the bulk off with isopropanol.


Anyway I think once I consult my previous posts to reinstall the electrics  %%  She will be getting wet at Kirklees on Thursday.

Odd that the Tamiya paint didn't cure properly. You could try contacting the Italian guy who's doing the YouTube build, he may have an inside track with Amati. Or maybe CMB, I don't think a direct approach to Amati gets very far.  I'm not using the Amati pads, too heavy, just saying.  %)


Be good to see how the hull rides on Thursday, don't forget some pics.


I'm not too far away from same outing, just need to get some new exhausts in and sealed, and maybe finish the underside painting now I've started it.  A couple of weeks.
