The lower the number of turns, the more powerful the motor will be. This certainly comes a price though. A faster motor will require much more frequent rebuilds, more custom gearing changes, reduced run time, more powerful speed control, and puts more stress on all components of the car.

If your just going to be bashing around, I suggest a speed control with about a 15 turn limit and perhaps a 17 turn motor. Novak makes the XRS that is cheap ($50us), small, and has reverse. It's very simple to use and comes with all the typical connectors already attached. Plus it will still allow you to use the many mod motors. Your won't be lightening fast, but it will certainly get over the jumps.

It will also be necessary to re gear the car to keep the motors from overheating. A smaller pinion and/or larger spur gear will keep the stress down and keep heat under control. For bashing, you want to be able to keep your thumb on the motor can for at least 3 seconds. If you cannot, you need to let the motor cool before continuing the run. This will insure your not burning up the motor prematurely requiring the motor be rebuilt (have the commutator cut on a lathe and install new brushes).
