motor not turning

[Hamiltonth]

A few minutes into the second flight of the day, one of the motors became intermittent and then stopped. After connecting to the Typhoon H GUI app and conducting speed controller testing of the motors, that motor did not turn (while all others did) yet there were no failure notices. Anyone have experience with that issue? Any thoughts?

If you’re handy with tools, use a voltmeter to test voltage between the motor and ESC. If you have current the problem is the motor. If not you have a main board problem.

Almost sounds like a motor lead has become disconnected. I'm rather surprised it doesn't show up in the GUI.

Thanks. That would have been way too easy! I had an extra motor, so changed it. Still no go.

Very time consuming to access the bottom of the main board but there should be fuses on the ESC's.

That’s why I suggested the voltmeter...

This may be a job for the repair shop. Thanks for the advice gents.
