Nitro drifting is ok and will not harm the motor if you run it rich and you run a hot plug so the extra rich setting won't blow out the glow plug. It is kinda bad and good, it all depends how you set the car and motor up.
Bandit, I am not knocking your post or anything along those lines, but it will be ok if you run it more rich than normal. Running your motor rich will disable the motor to rev extremely high and isn't to bad. Now the motor still won't last as long as it would if you were just driving on and off throttle because it is still running at a higher RPM longer than if you were driving.
Hope this helps, no hard feelings Bandit or anyone else.
