Unlimited Hydroplane Size does matter

[Brushless55]

What about the Castle 2028 motor on 10s?

[LarrysDrifter]

Id sell it, or hang it as a display.

Hi there people this is my first thread on this OSE. So i raced boats before in the 1980's and always wanted a Hydroplane. So i'm starting again, and i'm making 2 1/8 scale hydroplane boats. I've started on the Atlas and Pay N Pak. My question to all is that is there anybody with a 1/5 scale Hydroplane Brushless Electric boat. I've seen boats that is 1/5 scale but not electric and can a T5692 Turnigy Pro Comp Brushless Inrunner Motor 780kv do the job. and what size prop would I use. I wanted to use a 3 blade prop if that would help. I've attached 2 pictures of this two guys with 1/5 scale hydro boats. I'm Starting that build as soon as the Plywood from national comes in.

The possibility exist's to run twin's with these http://www.mhz-powerboats.com/mhzpow...ca69eba01db02a

These are capable of almost 6000 watts continuous, with a max of 8000 @150 amps. Running on two 10 cell Nano-tech's, 1 powering each motor with two good ESC's would possibly get it up to 40-50mph. But of course the more hardware the heavier she gets. A single lehner is also a good choice but i'm sure it would be taxed pretty high unless the hull was very lightweight and speeds would be difficult to get in upwards of 40 unless you had allot of room and allot of mah's!

I have to agree with Jay (Fluid)...big boats are very cool but the cost ratio is ridiclous....continue if you wish and I will want to see the video of the boat running and total cost.

THX, JIM

PS: A hydro that large could run 2 of these to a single drive. Check our OSE forum threads on how to do it.

I wouldn't bother with an electric drive train in a boat that big. There are lots of options
Gas engines that would move that hydro Use an X482 prop.

LOL..
so you think 16 to 21 hp only gets 40-50mph?

[Brushless55]

heck twin Leopard 5692 730kv motors on 10s each would kick ass in this hull!

Just a suggestion Brushless, I have no idea how heavy a hull that size is. Seen one up close but never handled it. I would think you would need allot of room to get it up on plane but for something that size, who would run it anywhere else but on a large pond or lake?

Oh bro, I would love to see this hydro with that much power!

Not only see it but have it!

I would talk to the guys that already build and race 1/6th scale hydroplanes they know what it takes to run boats in that size range, although a
1/5 scale is quite a bit larger.

here is a thread from Rum Runner Racing forums that talk about 1/7-1/6 scale hydro's and the power requirements that are needed to run these large boats. I would contact the them and start there for your project.

IMO IF I were to build a boat that large and wanted to do electric I would start contacting Steve Neu at Neu Motors and tell him my plans and see if he could come up with a custom brushless motor that would fit my needs, mostly because I would want the boat to be in the 100mph plus range.

That's a great idea Sean!

What an extreme idea. Just put an in-line gas motor or a Matha gas engine in that hydro, or stick to 1/8th Scale. Then those of us who have actually done it....... Can help you!
