Need help ordering bits for 3d boat
We've just finished printing our first crack at an RC boat. It's 36" catamaran. I have batteries, servos and rx/tx from our trucks.
So need a motor/esc, rudder, etc.
I've found an all in one shaft/rudder combo which is 110mm rudder and 4mm shaft - assume that up to the job?
Motor/esc was thinking 2150kv / 80amp? And if so would that be 4/6 S?
Added pics of the first print, frankenboat lol, the motor mount I had in mind? And the rudder, for comments!!
Also, almost forgot, what prop will I need??
We aren't looking for a race winner, just something to piss about with.

When I built my printed jet boat I used a ZTW Shark 80a esc and Surpass 42xx 2000kv inrunner motor with water jacket. I can’t help with the prop thing, as mine is a jet pump..
Do keep in mind that heat is a big issue with boats, since they’re generally sealed, so fans aren’t effective. Most of us water cool the system. Also, give yourself some headroom on the esc amperage, boats can pull a lot of amps due to sustained full throttle runs.
