[cut boat]

hi, im in the uk living full time on a narrowboat, i have a Ferrari boat that i would like to restore, when it was running it always seemed to under perform so i thought id come and ask some experts as we seem to be years behind you guys.....


is it a kit or scratch build? i would like to make it quick and handle if possible it was always quite slow......it is 30 long..12 wide....prop is 30mm...brush less motor is 30 mm prop is 30mm..3mm prop shaft..speed control is Apollo 25 2-6 lipo.. would you please tell me what brushless motor,esc,prop and battery i need

thanks in advance

Dang, what kit/model is this? I’d love to make one of these!

[cut boat]

hi, im not sure to be honest,iv had it ten years.i bought it at a club rc boat jumble....its made out of ply wood and looks hand cut...this is all i know about it

[Jesse J]

Wow, well.. welcome to the forum!!
What are your goals? Race or fun? If race what class? If fun what speed?
We can help you with these questions answered.

[jfrabat]

That is one sweet looking boat!

[cut boat]

hi, iv stripped the hull out and started sanding, there are a few thin bits and some hole, which west system product do you advise?

[785boats]

Is the canopy carved from solid wood?
If so, it looks like it may be one of the static display models made in Vietnam, similar to the one that I bought & converted to R/C.
However the one I bought was 38" long.
Could you clarify what size & kv the motor is please? It is not really clear from your description in the first post.

Hello, it is a very beautiful boat. Can it be an Amatti kit ?, or at least the fuselage.
https://store.amatimodel.com/en/mode...ari-b1604.html

That fuselage is a model that I would like to build. I can't afford to buy that Amati kit. But soon I will try to reproduce it.
I recently finished building one of the same family:

And I'm on my second construction with a different plane:

[Jesse J]

Golfito, are those kits you build?

[golfito]

Hello, no, they are not kits.
In the first photo I used Gary Finlay's plans as a base. Wood cut to saw. The Ferrari fuselage was built under a blueprint supplied to me.
The second photo, I used the plans that accompanied the Ferrari fuselage, that if laser cutting was used.
And I look forward to an Arno XI fuselage, also a visible V12 engine ...
I have the construction and plans published in another forum if you are interested. They are my first constructions, I try to gather information and knowledge about these boats.

If you want more information about the plans, we will contact you.
Regards.

[785boats]

A bit of inspiration for you.

[cut boat]

thanks for taking the time, i will get some pics of the progress in an hour or so...have ordered all the parts now

[golfito]

Beautiful video.
I'm still undecided. I already have an Italian model. I also like the American boats from the '50s.

Waiting for photos of progress, she is a beautiful model.

Hi, .iv replaced some of the bottom of the boat were the old shaft came through the hull then used 17g fibre glass cloth and west system to strengthen and water proof the hull,then sanded back and grey primered...the deck has been sanded and a piece fitted at the bow to replace some damage .....the upper part is plastic had split along the length so have repaired that and made it all one piece. I plan to use a hidden water tight deck to stop ingress of water and sit the top over that.....if ordered a 3660 water cooled motor 2000kv ..4mm flexi shaft and a 38mm two blade prop....how fast should it be with this set up?20200703_045710.jpg20200703_045615.jpg

Its plastic ..think the boat is a amati kit..

[Jesse J]

Again, Wow! what a cool project!
As for speed... are you looking for scale realism or do you wanna see how fast you can make her go? Why not do a solid shaft drive for extra realism?

If it were me, I’d probably be looking for 30-40mph max. And if you ran proposed set up on 4S you could see these speeds. You will probably need a 40-42 mm prop and in that case I’d be looking at a 120-150 amp esc just to be safe.

How much does she weigh?
How deep are the sponsons? I would be ready to add ride pads to deepen the tunnel.
Is the tunnel flat or steeper toward the bow?

This makes me want to try one as well!

[golfito]

t looks like part of an Amati kit. The boat can also be an excellent reproduction.
I'm glad that ship comes back to life.

In my 1/10 boat of 920mm length. I used a 1500kv 4082 motor, a 150A esc and 6S lipos. It is a heavy ship,
Use a 6S 1P (3s + 3s series), 5A, 45C Gens Ace configuration.
RTR weight 4750grs
1500kv XK 4082 old Hobby series motor
150A Flycolor ESC.
External 6V BEC and an economical waterproof servo.
HobbyKing 43MM propeller, also old.
Diameter: 43mm
Step ratio: 1.6
Number of blades: 2 Shaft size
: 4.76 mm
4.76mm flexible shaft with Teflon tube. Slightly curved

The following test is carried out with a measured value X442. And maybe try 6S 2P setup.
regards

[cut boat]

mine is the same kit as this

hi, it weighs ....1.5kg.........with no, motor...esc...battery..steering servo.....

sponsons are 13mm iv added a few pics so you can see .......iv fitted a flexi shaft today and the rudder do these look ok? iv ordered a 3670 2200kv motor rather than the 3660 as it will be here in a couple of days....where does the point of balance need to be?20200704_024532.jpg20200704_025207.jpg20200704_025239.jpg





a few days

[Jesse J]

If it were me, I’d add up to 10mm to sponsons and look to balance 1-2 cm behind sponsons.

[785boats]

I have mine balanced at 30mm behind the heel of the sponsons. Bear in mind that the original boat was a straight line speed runner, not an oval racer. Hence the shallow sponsons.
Here's a link to what I did with mine if it is of any help. It was originaly a static display model.
