after crashing from about 5-6ft onto hardwood floors, one of my motors stopped working as it did before.
It has a hard time starting after a rest period. If I give that motor a hand spin it comes back to life with a little power applied, sometimes I can wake it again by increasing yaw to high to that side of the quad and it will jump to attention as well. once it is up and running the quad flies continuously for a whole battery pack. It is only after a rest period, say a few hours or overnight that it goes into a semi-coma.
the motor does not run any hotter than the other 3 although it doesn’t quite stay spinning as long as the others, it might feel a tad stiffer by hand but not much and obviously not enough to cause odd flight behavior.
Directly after the crash I remember smelling a faint burning electronics smell or something, there was no smoke.
guess it might be time for some new motors just to be safe I don’t want to lose any flight time.
