One motor requires more throttle to start spinning

Posted by nickthecook on July 9, 2014 at 8:51pm

Hi,

I've got one motor on my 3DR Y6 that won't spin during a motor test, or when the drone is armed and MOT_SPIN_ARMED is set to "Slow". All other motors respond to the test and the arming just fine.

However, if I give the drone a little throttle with my Tx, the other motors start to speed up, then at some point as throttle increases the motor in question begins to spin as well.

Are there common causes for this?

    For posterity, after recalibrating my ESCs all motors spun roughly equally. All responded to motor test and Very Slow spin on system arm.

    I had just replaced the motor in question, and didn't think I'd need to recalibrate the ESC, but that seems to have fixed it.
