Hi lads - my first post,  I know nothing about model boats so I bought one - there you go - make your own mind up on that - I probably paid too much too. What I was sure of was that I didn't want a kit nor to scratch build just yet either (but a big tug one day). So I bought a late fifties scratch built craft described as 'a well made solidly built model speedboat of that era. The model requires a repaint,replacement cockpit wind screens and replacement cockpit coaming strips. Originally it was powered by a marinised 0.75 Mills diesel model aero engine but this has been removed' Well it certainly is solid, well built and needs everything else beyond that. It's a twin cockpit hull with two deck hatches, it's approximately 62 cms long x 22cms beam. It's a real pity the original engine wasn't included too - the guy kept it - that does mean I can go electric, which I wouldn't have done if I had the original engine - just wouldn't feel right to do that .The Cockpits seem out of place to me so I am considering having a superstructure hiding them - I'm not sure. I'll try and attach some photos.

Anyway before I pop off to Skelmersdale Scale Hobbies (not too far from Liverpool uk) I just wondered what a full brushless set up might be - just to get me on the water asap. From prop thru motor esc and maybe Lipos and charger. I'm not broke lads but I can't just waste cash either. For RC I have picked up a Fly Sky GT3B 2.4ghz 3 Channel Radio Control and a reciever - is that ok? I picked up three more recievers on ebay quite cheaply - I'm planning a scratch crane barge first - then I'll be asking about powerful tugs. My life is about to get some much needed me time. This weekend a big shed goes up so I can also work on two dead scooters from 1959 - a Durkopp Diana and a Heinkel Tourist.

where are you by the way ?

[Norseman]

Hi There

Thanks for the quick reply, I'm not too far from you - just down the road in Huyton - I'm quite near to The Hare & Hounds pub.

What lipo power pack /charger do I need? The charger is eventually going to be covering more than one crafts power so that's why I am asking you rather than just searching for the very cheapest models.

I've added the type of superstructure I'm thinking about adding for a makeover - I like it but I'm I'm undecided - I think originally I saw the Ilka Pilot on this site.

Cheers Norseman

Norseman,

I'm even closer to you, I'm in Page Moss, Ive not started on here just learning the trade so to speak I'm collecting all the bits and pieces needed to build my first scratch built boat
hope to start very soon.

cheers

I worker in Page moss for 20 years Just behind the Eagle (that was) is it still a demilitarised zone?

I would go with Nimhs there is no need for anything else ,and are easier to use with not having to worry about over discharging or over charging. the prop I would email Mtronik and see what they recommend for that motor and controller combo. but if not go small and work your way up.

I'm going to agree with the use of Nimhs rather then lipos, you can still use a brushless motor and speed controller with nihm battery's, lipos are a lot of hassle for a boat that you just knock around with, they are quite an expense compared to nihm...chargers, balancers , life of the lipo itself, its a constant spend for very little reward.

[Norseman]

Hi All

I'm learning from your replies - so no lipos, and an esc/motor combo has been recommended. What about the prop (see pictures) and its servo lads? (oops ladies too)

Re demilitarised zone - I live on St Johns and that varies from quiet as a mouse one day to downtown Beirut with free industrial fireworks the next day, so I really can't knock Page Moss. What matters is who you mix with and who you want to be, but it's really hard on the kids to have to be making those choices so young. I'm 54 and I'm glad I'm not 15 - No-one ever sees the good in any kids they find on the street simply because a few badun's have got us all frantic. My view is most kids are capable, clever, and kind if given the chance.

Sorry - I was building up to a soapbox there ............. oh and don't let me get started on Herons.

This is a great forum and I'm going to enjoy being in it as much as I am going to enjoy modelling my boats and fixing old scooters.

Any standard servo will do the Job. £6 avg from any good model shop as for the prop can you give us some dimensions of the hull ? length width, depth, ( this will give us better indication of which prop is best, at a guess 35mm should be a good start point)  and the Prop shafts thread size, i'm assuming its in old money possibly 2ba, which means you will have to either source a prop with the right thread for the old shafts cut, or buy a prop with a very small thread and re-cut it to match the shaft size.

There is another option which would be to change the shaft ( not the shaft casing that's glued in the boat) to today's thread sizes, you could changed the entire shaft if you think its easy enough to pop it out with little damage ( the glue may be old and allow to peel it away with a bit of force)

Let us know these details and see if we can aid you further 

[craftysod]

You already have the the power in the boat,a bean can,wind powered

[HS93 (RIP)]

that will prob be a 4 ba shaft they all where in that era. what you can do is use a new shaft and bearings and go M4 I can probably help with the shaft , you just need a cheap standard servo wherever you buy your radio gear they should have one . as I said with the prop you need to ask Mtronicks if that is what you buy they will know what works well , it will prob be a 30mm two blader , you can get a 4ba prop to go with your shaft.

go smaller with the prop and work your way up keep checking to see if anything gets warm.

[Roadrunner]

2ba-4ba props availible here, but i doubt you will get a 30mm prop in that thread size... but 35mm are there in the list which as i said before a good starting point, you may even need a 40 if going brushless.

http://www.rcmodelcentre.co.uk/rc-boat-props/cat_68.html?sort_by=name&sort_order=low&page=0

I wrote 2ba as the shaft size as going by the photos she was not a big boat and was possible that the shaft could have been smaller.. hence why i asked for dimensions, although you are quite right it probably was 4ba but you never know with some of these boats!

[HS93 (RIP)]

35 mm on that motor may overheat it, I have used similar, they are a very small small motor . Prop shop do 30 mm props 4ba I  have several
I find it better to go small and if it revs to much it does no harm where as a prop that is to big can burn out a speed controller and damage the motor. I have found brushless setups can take a bit of swooping of props
again as it is sold as a boat combo mtronicks will know what is a good starting prop is.

Hi

Sorry, I've been busy with the greenhouse coming down today. Ok I've measured the boat again. 63cm L, 23cm W, 13cm D, 3.2Kg, 2 blade prop 35mm, and 40mm would probably just clear the bottom. My friend got a motor and connector from Cornwall Boats, he wasn't sure of the size so they sent him two (no charge) the smaller one fits mine and he gave it to me. Ed said it was BB but I think he misheard. Maybe I could just start with the prop and shaft I have?

That reminds me. He got a Graupner 700BB and had to solder suppressors onto it himself (it's for his grandson). Is that the normal state of affairs with motors? And if both poles were connected to the body by this why doesn't it short out?

Regards Norseman

[HS93 (RIP)]

some 700bb already have capacitors, we have never botherd, which 700bb is it ? also if you use 2.4gh radio you don't need them anyway.

Hi

I'm just back from a long day at work and I'm having a welcome  cuppa coffee. Ed's motor was a graupner on the label but I suppose it might have been sub contracted out? His radio set up isn't 2.4, mine is though - it's the FlySky gt3b set up - I hope it's ok.

Hi Peter

I was just about to order from Howes the combo you suggested but looking through the specs it said

Recomended model weight - 300-800g . My boat is 3kg so is this ok and I'm just misunderstanding what I'm reading?

Regards Norseman

[HS93 (RIP)]

That 300-800kg is for planes i think that motor is fine a nice electronize speed controle will be great for it.

Hi

life got in the way and I only returned to work on the boat today. In the end I took a trip to Scale Hobbies in Skelmersdale and got what I needed to kit her out. I took the boat and the owner looked her over, he said the prop and shaft were ok (I have a RC already), and then sold me the following: metronik vision 500 burshed motor, mount, cables, JP brushed speed controller 50 amp +rev, Saturn 3kg servo, Nimh 8.4v SC-3300H flat battery, suitable charger, small sundries. Along with that lot I got a fair bit of advice too - so  .

If I'm not happy with the end performance I can upgrade later and use the brushed stuff for my crane barge - so no waste.

I have met with two problems so far today
1. The little grub screw for the prop/motor connection is missing -  hmmm - deep toolshed search called for - or 36 mile round trip to Skem'.
2. The old wooden beam that the IC engine was mounted on was not only screwed in but also glued and then secretly nailed in - it's going nowhere. It was in the way of the motor lining up with the prop so much removing of wood with a dremmel type tool was called for - and of course it wasn't softwood - oh no.  So now I can get it in, the mount holes are not actually over the beam but hang outside of it - so now I'll have to add some wood and glue it in.

It's trickier than I thought this modelling business - I think I need some more appropriate tools too. My planned christmas start to a build of the Kalakala is looking more daunting now, but never mind I'm making progress.

Hi

I started out thinking this was scratch built in the late fities but Circlip knew better. He sent me an old 1953 advertisement - the boat is an A.A. Hales Ltd Spraymaster and just look at the price  that wouldn't buy you the magazine nowdays.
