N5RMQ

I am new to electric so and I need your oponions. I have a Turnigy motor and ESC that I have run about 4 times and all was well. This weekend as I would apply throttle s l o w l y it wanted to run backward, and seemed to have a lack of power altho it was running (by ear ) at the same RPM as before. My 10 x 7 prop had a small chunk missing from the tip, would this cause a loss of power? and whats up with the wanting to start backward? Thanks

N5MRQ,

Does it tried do move backwards slowly and them moved forward? if so, that mighr be some bad welded wiring...
I had problem once and the bed contact wire was the signal wire pluged to the receiver.

also, the missing portion on the tip of of your proopeller would not cause RPM loss, but will demage your engine axis or bearings...

Hope it helped.
Mauricio.

Did you switch some of the leads on the motor? Try that.
Also, check the balance on the prop. If it is still in balance, you can still use it.

Sensorless brushless ESCs may wiggle the prop a little at startup to figure out the position of the rotor. As long as it finally spins in the correct direction after that, you should be fine. If you are having problems other than this initial wiggle, then you probably have a motor or ESC problem. If your motor or ESC has been running hot, you may have damaged the motor windings or the ESC electronics.
