yes, if you lock it you can use the motor and esc for reverse. As far as selling your 3 speed it depends on what gear you want to lock it in. You could sell the 3 speed and pick up a standard 2 speed to lock it all depends on you. Either way will work fine. I do not have a write up but i can tell to take the clutch in the gear you want to lock and take the screws out so the shoe that comes out is free. Hold the shoe in the out position and jb weld it like that. good to go.
