Mid flight, my front right motor/esc (not sure the root cause yet) started oscillating strangely (audible noise), there was no crash that caused this, the propeller is on correctly (I flew 2 flights fine with it). The motor screws have threadlock applied, and the motor is secured tightly onto the ZMR250 arm.

Not sure what the issue is, suspecting a defect in the motor or esc, I will try cleaning the motor and seeing if there is dirt that might have gotten lodged inside (sand/rock?)

----------------------------------------------
UPDATE/SOLUTION: The problem ended up being a broken capacitor leg on the ESC in question, the vibration pushed the cap against the frame and it broke free. Upon cutting open the ESC shrink wrap, I discovered it hanging off on one leg.

Upon re-soldering the leg, and adding some hot glue around it and a couple other ESCs the issue was fixed.
