I have a 650 pump and a 750 driveshaft. But not sure I want to spend the time or money on this thing doing a pump swap. and Keep throwing around the idea of putting this drivetrain in my carbon freestyle ski.
Went out with the x2 trim installed! Picked up 1mph on the top but best of all it keeps the nose down while in the down position. So far biggest con is steering has a lot more resistance. So when the kiddos drive me around while I drink on the back seat they are not able to turn as quickly.
Took her out for a ride on fully charged battery and put the motor/controller in full power setting. Only hit 18mph. Not sure if I should go up to a 17 or down to a 15 degree impeller to get rpms/speed up?
