I think that you can run motors 30000 RPM unload with 4S batteries, 2000kV.

Edit : TFL 36mm pitch=1,4 for 3/16 shaft works with this adapter https://www.offshoreelectrics.com/pr...prod=ose-83400

Rcboat blitz.. website says no exports.. 1.9 pitch? Ugh too much work for this system.. I’ve seen these options and more.
I’d rather trim down 38 mm than overload these guys with high pitch props.
Thanks tho.

Super glad I did a removable module of power and torque.

I don't know if she will be fast, but she sure is pretty!

You can run 4S per motor easily with 2000kV Motors ...

Here is a cool winshield :

Happy with turn out. Not looking to break any speed records on first run.
Still need to sharpen and trim down props, get her balanced and increase water flow before trying 4s.

Jesse, where have you found best CG with this hull? I have mine on the table in layout phase. Sw 220, Castle 1100kv motor and 4s for rough water I?m thinking. 45?ish prop

Hey Shawn,
I’ll have to dig out the packs and measure to be sure, but I wanna say 28-30%. I’ll take a look and update if needed.

That sounds like an 8s set up.. I wonder if it will even get up on plane on 4S?

I have a healthy sized lake that I frequent, winter is breezy and rough at times and summer is popular with boats. I‘m thinking this hull will be fun on that water. The motor is an outrunner so don’t wanna push the heat much. But you have a valid point. I do have 5 and 6s packs as well. Perhaps I should set up 30% with 6s packs. Lots of room to move weight forward, not so easy to get it back.

[srislash]

Oh and Jesse, do you measure from prop or transom?

Thanks for your time, Shawn

[Jesse J]

Wetted surface, so transom.

[Jesse J]

Any progress brickbait?
