General Information on Radio Controlled Car Motors (Part 2)

Another way to keep peak performance is to be sure that the com is true. This is accomplished by regularly cutting the motor on a com lathe. Doing it about every 5-10 runs may seem excessive but doing it so often, it ends up only end up taking .001-.002 from the surface. Since taking only such a small cut, the motor can be re-trued upwards of 25 times.

Springs are yet another way to alter the performance of a motor. Asphalt is for Racing, Dirt is for Planting Potatoes. Anyway, in 4-cell 1/12th scale, it is best to run LIGHT springs. Run a Trinity gold on the ‘+’ and a Trinity silver on the ‘-’. This has proven, after what seems like months on the dyno, to be the best combination for 1/12th scale STOCK racing. 4-cell mod follows basically the same rules of thumb for springs, but the timing needs to be adjusted for maximum efficiency as well to take full advantage of what the motor can do.
