My motor stop spinning for a sec.

[Chris Anagniou]

Hi guys!
I am flying in X mode.
The down left motor (aka. number two motor) , stops and starts immediately and make my quadcopter to lose height.
This has happened the last two times.
I think it might be the ESC and i'm planning to test it on another motor.
Has anyone else had the same issue?


My current build setup is:
-apm 2.8 with arducopter 3.2.1
-S500 frame
-Sunnysky x2212 980kv
-Mystery M-30a (flashed with SimonK firmware)
-1045 Nylon props
-5000mah 3s lipo
-walkera devo 10 rx/tx

P.S Sorry for my English if you find a mistake.

The most likely suspect components would be the motor and the ESC. The first thing I would replace or test is the ESC, but It's possible that it is the motor. Sometimes the motor's windings are not very tight and uniform, and can occasionally cause problems. (This is uncommon, but is possible. I actually got sent a bad motor for my last build).
