Ferrari Hydroplane

Stupidly or otherwise, I put a bid on this gorgeous thing this morning & won it for $350.00 plus $50.00 shipping.
It is 38" long & will be a great sport boat. No need to over power it as I'm aiming more for the scale look rather than racing.
I'll have to wait and see what the insides look like before making any set up judgements. But 6s & maybe a 4082 1450kv, or there a bouts, should do it.
Hope you guys like the look of this baby as much as I do.

That looks more like a mantle decoration. Way too pretty to take out and race.

Thanks F1. I'm glad you like it.

You are right Bill. It is listed as a static model, but also with the option of R/C conversion. The cowling is separate, and if the model is like other boats I've bought from this guy, the inside should be resin coated.
We'll see when it gets here.

I'm thinking of using the original rudder system & also a straight drive shaft like the original prop riders.
So, is there a specific type/style of prop that is more suited to that type of set up?

Man that is a beautiful boat - looks as if it could have been designed by 'ole Battista "Pinin" Farina himself.

Wow..............beautiful, love the detail in the cockpit..........gauges, 'leather' seat....................VERY NICE!!

You may consider a motor in this size for scale speed. Its only 130kv so if you run it on 40s that would give you around 20,000 may have to swing a bigger prop at that 'lowish' rpm though...........maybe like an x470...............its got the torque to swing it

Just trying to give you another know me..........always trying to 'help out'..................

It seems to me you would have to run it at least once, then it can collect dust on the mantle.

OK........serious business now, these are great prices on 4 polers and either should work on 5-6s

I own two of these new Turnigy motors and they are good quality from my experience.

Do you have any more pics or video of that boat or link? I had looked at it often but heard bad reviews.

Thanks Osprey.
I'm not sure who designed it. Could have been the owner & driver himself, Achillie Castoldi. I think Ferrari only supplied & maintained the engine.

I knew you would appreciate this one Scorp.
I think I'll pass on your first choice of motor though.
The other ones are more like I had in mind too, Most probably the 1400kv.
I've got one of the 3674 2200kv ones & it's every bit as good as the same size & Kv Leopard. So I have faith in them.

I'll be running it more than just once I can assure you.
I can see your point of view, but I think it's too nice to just sit on the mantle collecting dust. It needs to be in it's element out on the water.

As a sport boat that hull should be something else

However have you thought about a lower KV motor in it?

I ask this because this design is relatively narrow and has a short after plane so it isnt as stable as a modern design. Also the model isnt light. These factors increase amp draw. The actual boat was ultimately used to run speed records so its top speed of 150 mph was not respresentative of the 800kg class speeds on the oval

On 6 cells a 1450kv motor using a scalish prop a 2 blade 50mm (say Octura M or P series) will draw relatively high amps so the runtime will be short short

IMO a motor closer to 1200 rpm will give you the speed and lift for that type of hull without huge rpm eg M450/81 kph P1750/98kph a bit quicker than the 95kph scale speed

Look forward to seeing your vids of it running

Thanks for your suggestions Andrew. I do appreciate them & I understand what you are Saying. But the reason for a slightly higher KV is that I'm thinking of using a straight shaft (as in photo #2 in the first post.) This puts the prop under the hull & I don't think a 50mm prop will fit. So I'm hoping that a hgher KV spinning a smaller blade prop will lift the tail with the angled shaft. Just like the full size ones.
This may all change of course when I have the boat in my hands. I may need to set it up like a typical hydro. But I'd like to keep it scale if possible.
I know what you mean about the heavy tail on these wooden models. I have converted an old Equipage Tornado 80 to brushless. Its a heavy 30" hull I've only got a 4065 1800kv motor in it on 4s with an X440/3 & it does the sort of speed I was after. Not a race boat but good sport fun.
I'm hoping that this hydro will be a bit quicker but any suggestion on prop type or style for a straight shaft set up would be appreciated. Cleavers? Choppers? X series? etc.
Here's a clip of the old Tornado 80 on it's first test run.

P.S. Will we see you up here in Brizzy for the Nationals this year Andrew?
