I got one of those motors back in 2000 and it still runs well to this day. If I remember correctly, the guy at the hobby shop I brought it from, said that the motor was originally meant to be a truck motor. This is why it had so much torque, which most of you guys seem to agree upon.
It was great for small to medium tracks. I never had problems tuning it either. As a matter of fact it was one of the easiest motors, I've ever had, to tune.
Just my 2cents. I've retired it from racing and mainly use it for parking lot bashing. I was temped to let someone modify it for me, but it runs so well, I figured, why bother.
