I raced one in my erevo (6.5 HV) all last year. It was fine. Geared for 35-37, I never had a problem with heat. Lots of people talk smack about these systems, but I was always competitive. Most tracks you can't get past 40 mph anyway. And sensored.... oh la la.

In a buggy, you should be fine. However I do recommend a slipperential.
