Electric OB on K&B 3.5/7.5 base

Hi Guys

I need to build two electric hydro motors. One for a 3.5 and another 7.5
on Prather FG hulls.

Who sells or makes the down legs and motor adaptors? I'm thinking of
mounting Align 350-500 inrunners on the 3.5 and the align 600 heli
motor on the 7.5

Any of you guys done the conversion, have suggestions, or motor/RTR
laying around?

Hey Bill,
Hyperformace makes a k&B conversion kit


Hi have a k&b leg I'm running a stock Proboat 1500kv motor on. Tunnel runs great.
I hear the OS leg is one of the best. You can buy them new at Towerhobbies.
