Got the motor mount today from impakt. The CC motor will not work as it has small screws that hold the endbells on, and they stick out the sides, effectively making the motor larger than 36mm in diameter. I tried a few feigao and hacker motors and they fit fine, will try out my 2500kv aveox and see how it does. If it fits I will run it on 4s lipo, instead of 2s with the cc 5700. Still need to mock up the chassis, and build the clutch.
