Anybody using the Novak Light motors for dirt or any other kind of racing. Their website says that the 4.5 is good for competition level 4WD off road racing, and the 5.5 is about right for sport racing in 4WD buggy and competition level 2WD. Just wondering if anybody is out there running these motors and what they think.

i just bought a 5.5 light. Have not used it yet. Putting in a T4. I'll let you know.
