Is there a brushless system that is faster than the stock one in the Mini Rio that is still water cooled

i dont think they make one. but what you could do because the motor mount is water cooled get a380 brushless and use a marine esc IE http://www.hobbycity.com/hobbycity/s...rushless_Boat_. good luck and happy boating.

what would be the best 380 sized motor and should it be sensored or sensorless i was thinking something like a feigao
