If I got this here I wouldn't need to dremel right?
In order to get gear mesh right yes you do. If you use a 13t pinion then you wont have too at all. Just to let you know that, that motor pod comes with the 180 motor plate. But you can take the 180 plate off and put on the 300 plate onto the motor pod.
