never ran hot in my crt.5 on 3s. Thats why i was thinking it could get the job done in the buggy. I was thinking dropping to like a 14 t pinion to help the motor get in the rpm range quicker. But not sure waiting to here more peoples opinions.

As these motors have never got hot on me on any setup. But i am sure the weight of the buggy will give it a little bit of a hickup.
