Set up for 56" Fountain Mono
Hi all, new here and first post.
I am building up a 56" Fountain style mono. Looking for opinions from seasoned RC boaters. My plan at the moment is -
Twin 56112 700kv motors at 10s 300amp Flier ESC's running twin TFL steerable Arnesen drives. The props I have from previous projects are counter rotating 6717/4.
Does anyone see any issues with this (be kind).
Another option I was toying with is -
Single 56112 700kv running through a TFL transmission with the same drives and props.
The props I have mentioned are ones I already had so happy to explore other options.
Thanks and looking forward to your replies.

Prefer higher voltage, 2 x 12S and 650kV motors, 30000 RPM unload.

2 x Outrunner motors is a good choice, high torque is very good for a big hull ALIGN Outrunner Motors

It is impossible to give an informed answer to the OP without knowing his goals for the boat.

- organized racing?
- general sport running?
- short speed runs?
- top speed goal?
- runtime goal?
- experience level building FE boats?
- pond size?

Hi again, sorry, probably should of included a bit more detail. No racing involved, just a general runaround. Like to get around 50mph. I have built large gas boats but this is my 1st large electric one. I will be running it in either a large body of water or in the open water so pond size is not an issue. I am now looking at a TP power TP5670 850KV 12s through the gearbox turning twin 55-57mm dia 1.4-1.5 pitch props. ESC I have is the new Flier 320amp.
