WHY WON'T MY RTR TAKE OFF FROM A STANDING START?
QI have an RTR 1/10 scale SCT with a brushless motor. It was running reat for a few months, but it has developed a problem. Sometimes
it will not take o; from a standing start or after a wreck. However, if I give
it a little push and then pull the throttle trigger, it will start running and
seems to run fine. What could be the problem?
A ;e problem is likely due to a faulty sensor in either the motor or the speed control. Brushless motors are characterized by the number of
poles and the number of phases that they have. ;e number of poles is the
number of north and south magnetic poles on the rotor. Most brushless
motors have two poles; however, four-pole motors are becoming popular
aftermarket options for short course trucks.
As a standard, the rotor in a brushless motor has either a single or double set of north and
south poles that are used to make the motor spin.
Brushless motors use sensors on all three phases in order
to detect the rotor's position. If your vehicle won’t work
on its own, you might have a faulty sensor.
