sounds really cool. Good luck with your build...….
Thanks, do you have an idea about diameter and pitch for the propellers ?
Geez, I guess you’ll have to go CNC to get CR props but I’d think 37mm could be a good size, maybe 35mm? I have a 40” twin mono running 442’s and it is running 50mph. TP 4030 1180kv on 8s 4200mah. I know it’s a different setup but it gives you an idea that you don’t need huge props to do well.
I was thinking about 38mm x 1,4 pitch for the props ...

I've built a couple of twin monos,there are pics on my page
It's currently 2x SSS 4082 2200 KV on 4S with 150 amp raider ESC's and 44mm 1.4 props. Cheers .R Beer. p.s. A generous hatch size is important when selecting a hull for a twin!
@ RunningBeer
You build a "double" setup mono ! 4082 motors ... Is it a very fast boat ?
There's a bit of vid from an early run here https://www.youtube.com/watch?v=tobZ3H2icco . It's quick enough for my driving. The best part is how tight it can carve left and right turns.
I have 2 sets of motors :
- 2 x 2960 2200kV , 175 Gr per motor
- 2 x 3660 2400kV , 240 Gr per motor
3660 motors are too heavy imho, what do tou think ?
The twin pursuit on my page had twin 3660's 2200KV on 4s. It's a similar size to what you are building.It was a weapon but I didn't reinforce the hull and she broke after several large crashes. I'm no expert but I think the 29's will struggle to dissipate the heat on a boat that big.
If I use 3660 2400 kV motors I' m afraid the boat will be heavy , + 130 Grammes.

Hello Alain !
How are you ??
Do you really intend to start such a project ??
Do you know that you will have to use a drill and make holes in your hull ??
You should do like the other boats you have, and leave it in peace on a beautiful shelf.
cheers
