Unlimited Hydroplane Size does matter

[egneg]

There is the Neu 4400 series that may work but it's limited to 10,000 rpm.

Is there a gear box out there that would allow the use of 2 motors and use a single driveline? If so, would it make sense to use it?

Welcome to OSE!
That is HUGE, I assume it's going to need a huge motor too. What number of cells will you use? I think a 56mm motor may not be enough, maybe an outrunner?
THIS is the biggest motor I've seen but the KV is too low

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.
