Geez another one of these? Is it really necessary? You know the answer.
Hitec all the way!!
If you want the best of the best there is no competition. Hitec 7940 and 7950 if you want to run unregulated lipo power(highly recommended btw). Or if you're running nimh or a regulator a pair of 7955's would do the trick.
I personally recommend the 7940 & 7950 combo if you have a receiver that can handle unregulated lipo. In buggy you can run a pair of 7940's if you like. I would recommend the 7950 for steering in a truggy though(the extra torque is good to have).
