You don't have to change the motor rotation direction. The motor plate and spur gear need to be bolted to the other side of the transmission housing. You put the 4 gear transmission together incorrectly. I suggest you look at the instructions more carefully when you are working on your car.

actually it was just a massive brain fart. I never even tried it. 4th gear cancels out turning the motor around. Duh.

so you ask for unessary help..LOL..

I want to say the kyosho car can have the motor plate on either side of one of their transmissions. I remember someone else asking this same question and it turned out he built the transmission with the motor plate/slipper on the wrong side.

At least you didn't buy a new esc for essentially no reason. I call that a win.
