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. Modfied 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! |
