I know I'm not even close to understanding everything in this hobby so would someone explain to me why you would want to change the engine out from stock?
I think the .46 is an awesome engine, it has enough power to move a battleship and the speed comes from the tranny setup so I think the engine is not a consideration for the speed.
So for myself and others that would read this thread a little elucidation would be appreciated.
Thank you!!![8D]
