Radio System FAQ
My airplane's electric motor runs in the wrong direction. What do I do?
First off, it's not the speed control. Model airplane speed controls have only forward, off, and sometimes propeller brake. The problem is elsewhere.
There are two things to check. First off, make sure your motor is wired correctly. Sometimes the "+" and "-" symbols on the motor are not correct for your installation, and you really have your motor wired backwards. You can easily check this with a tach. If your motor turns more RPM in one direction than the other, the higher-RPM direction is the correct direction.
If your motor is wired correctly, but the propeller still turns in the wrong direction, you may have to change how you're gearing the motor. This usually happens when a gearbox and motor are put together by the modeler, and the motor was not purchased specifically for the gearbox.
