Getting Started with R/C Cars and Trucks
Motors
There are two basic classes of
racing motors: Stock and Modified. Stock motors have plain bushings, fixed
timing, and 27 turns of machine-wound wire. A stock motor can refer to the
motor that came with the car kit. Modified motors have ball bearings, custom
winds, and adjustable timing.
Before purchasing any modified
motor, be sure your speed control can handle the extra current that modified
motors demand. Never use a modified motor with a mechanical speed control
and always heed the manufacturer's recommendations for the number of turns
your ESC can handle. Turns means the number of times the wire inside the
motor is wrapped (or wound) around each pole of the commutator. Double,
Triple, Quad, etc., refers to the number of strands in the wire that is
used. Fewer winds usually equals greater rpm's and shorter run time. More
strands usually means smoother acceleration.
Smart racers know that it's not
the fastest motor that turns in the quickest lap time. It's the one that is
best suited to the track, car, and traction available, so choose the motor
wisely if you decide on a hot modified.
To get the best performance from
your new stock motor, break in the bushings and brushes with Trinity's
Bushing Buster and Revtech Comm-Drops.
Always clean and oil your racing
motor after each run. To get a jump on the competition, use your best motor
and a good battery pack in the first qualifier, when the other drivers are
holding back their best stuff, you could steal the TQ spot!
