Are they any good?
It works OK. There's a bit of cogging (as others have stated) - I tried both a Castle Sidewinder and a HobbyWing 60A. It was better with the HobbyWing. It might be better with a SpeedPassion ESC with a matching firmware. Once it gets going, it's pretty good. It does not get excessively hot, run time is good, and has good speed. If the track is not prepped or you have rear traction challenges, it can be a handful to drive. The endbell cap was a tight fit in my F104W's pod (aluminum mount pod).
