Title: Amati Grand Banks
Post by: Stan on August 05, 2019, 10:04:07 PM
Hopefully this will be the start of my build thread for the above model. Major construction will not start before we enter the winter period. It is very obvious that new materials will have to be used to reduce top weight this will mean many of the parts in the kit will not be used. The first pictures show the build board that will be used to construct the main section of the superstructure. More information will follow when the build starts.

That's a good solid board you've put together Stan and with plenty of space to get your hands underneath  :-))

Hi Ray I will be fitting some studs this will allow me to clamp down the base of the superstructure during construction.

Hi Stan.
What prop size have  you chosen and what motors do you intend to use?

Hi 30mm 3 bladed may go up to 35mm if needed. Motors are small brushless power will be from lipo batteries.

Hi Stan


You're off to a good start ,and very neat  (as always ), are the hull and deck made from GRP  ?

Just a few pictures showing cables fitted to the fuse holders  and the plastic tray made to fit the R/X equipment.

Stan. :-)) :-)) :-)) :-)) :-)) :-))

Technical info 
20 amp b/less motors.
30 amp E S C. 15 amp controllers would not meet  the motor needs
18 Amp cable.
Two 15 amp fuses protect all the above.

Looks good to me but I keep hearing from others huco couplings are bad, particularly with brushless? 


Is there any real truth in that? I use huco's myself on brushed but have some devolved into new rubber couplings which I read are mandtory for brushless with wanting to assure way-over scale performance.


Rich
Title: Re: Amati Grand Banks
Post by: coch y bonddu on November 15, 2019, 10:35:21 PM
I use huco on brushless but i set up the shaft to motor with a solid coupling so alignment is spot on also I either wrap the coupling with insulating tape or heat shrink just to make sure it does not explode as technically you should not use them with motors that rec more then 5k...My Models by design Cygnus hull has a brushless with 750 revs per volt and run it at 24v if I feel the need for speed thats 18000 revs !!!!!!!!!!!!!!!...not broken a coupling yet


Dave
Title: Re: Amati Grand Banks
Post by: Stan on November 15, 2019, 11:10:45 PM
The brushless motors in this model are small and I understand will rev about 5,000 rpm the couplings are well made. The speed controllers are from MTroniks with good speed control.

Stan
Title: Re: Amati Grand Banks
Post by: RST on November 15, 2019, 11:22:06 PM
So Stan and Dave / Stavros then it'ts just the usual -confirm everything in alignment -I also run my brushed motors off a single AA cell and "feel" if they strugle to turn it aint right.  Stan, no offence, you just hear so much anti-huco and rubber joint tech these days.  I've never had a problem with either.

Morning Stan
Nice set up your motors
On 7.4 2s lipo 5550 RPM
On 11.1 3s lipo 8325 Rpm


If you run lipo that is  :-))


I am watching the build

Hi just a few pictures showing first fix of electrical work. Please note the use of Wago 221 terminal blocks no screws to worry about. Speed controllers are from M Troniks  and the two way switch from Action. More pictures when full installation is complete.

Latest items to fitted in the hull are the two switches that  turn on the radio system and speed controllers. On the way a small pump to simulate engine cooling this will need to be tested on a jig pictures to follow.

Title: Re: Amati Grand Banks
Post by: Stan on November 21, 2019, 11:46:36 AM
All the wiring is now complete and tested.The next job is to lightly sand down the hull  to remove any marks made during wiring. Then back on shelf  for a while.

Stan.
Title: Re: Amati Grand Banks
Post by: Stan on November 22, 2019, 09:55:22 AM
Hi RST  I have run both motors at full throttle and the couplings seem fine. The most these motors will do is about 5000 RPM.

I have been today to my local car spares shop and purchased some 3mm windscreen washer parts. Saturday I hope to make a test rig  to confirm I can simulate water cooling on two outlets. Hopefully some pictures.

Hi, message received and very impressed I am too about your securing of parts through the hull.  Looks like stabilit express to me? But are you using masking tape round and peeling off each time while it is still green?

HI guys just a few pictures today showing the small pump and test rig to determine the final size of brass tube for simulated engine cooling. Next group of pictures show the first steps in superstructure construction. The formers are 5mm M D F  these will be remade using 3/16 balsa to lighten the build.

Hi Guys sorry for not explaining what the small fitting is. It is fitted on the suction side of the pump to protect the pump from damage. The filter is in two parts with a fine gauze fitted in one side hope this helps.

Stan. :-)) :-)) :-)) :-)) :-))
Title: Re: Amati Grand Banks
Post by: Capt Podge on November 24, 2019, 05:31:28 PM
Thanks for that Stan, yeah, better than pulling gunge from the water and into the pump, probably causing damage  O0

Thinking ahead then Stan  :} . What about putting a couple of 'taps' near the outlets for fine tuning the flow?
Something like the one on the left -

Stan. :-)) :-)) :-)) :-)) :-)) :-)) :-))


They look like Raboesch couplings, which as you say are nicely made and much better than the cheaper huco couplings which I wouldn't risk on anything. I have a couple of the Raboesch ones that I'm going to use on my slower models with brushless motors. I use the metal/rubber couplings in faster models with more powerful motors.


As others have said, very neat electrical installation.

One thing to watch out for with the filter is that they corrode when used with water. They are aluminium designed to be used for the fuel lines on glow motors with up to 20% oil in the fuel so will always be oily. When used with water there is no protection against corrosion and the mesh can be blocked unless it is fully dried out after each use.
Jim
Title: Re: Amati Grand Banks
Post by: Stan on November 25, 2019, 12:48:23 PM
Hi JimG I have two of these already in my models with sign of corrosion. For the amount of time they are used it would take a long time for any damage to take place. But they are maintained not just fitted and forgot but thank you for brining this to my attention.

HI guys more information for you. This model if built from the box and be used for R/C control will need some major work to lighten the overall weight.  Just to give some idea former 8 which is positioned at the rear of the deck section weights 1.1 oz made from 3/16 balsa it weights 0.2 of a oz. Lots of new formers to make. :(( :(( :(( :(( :(( :(( :((

HI all now back building once again. I have enclosed some pictures of the basic frame work for the superstructure. Most of these parts are having to be made from 2mm and 3mm light ply laminated.  Then using the kit formers new ones are cut from light ply I am having to do this to cut down on weight. Cutting new formers makes me want to  <:( <:( <:( <:( <:( <:( <:( <:(

do you have any photographs of an actual ship.


it is a very interesting build, and I look forward to following this build especially to fruition.

Hi guys after a disaster with the front roof section this has now been removed and refitted using 0.75 mm plastic card.  The rear steps from the fly bridge are now been made using plastic card the  wood ones will end up in the bin. Plastic card is so easy to work with no sealing of wood. I have enclosed pictures from the build instructions showing these steps using ply for construction.
