hi , me again, just starting to gather together some bits for my 1st build, I'm thinks about the motors, I know that two of them need to spin clock wise and two counter clock wise, this is obviously adjustable both in the Betaflight software or by swapping two of the wires around, I've bought a set of 4 dji 2212/920kv motors of eBay, I've just relised that all four of them have cw i.e. right hand thread on the lock nuts, surely two of these should be left hand thread, to stop them loosening ?.. am I right ??
Most manufacturing of CCW motors is a thing of the past. The motors that are spinning clockwise are the ones where the nut can come loose and to prevent this just get some 5 mm nyloc nuts. Readily availabe anywhere
I've never had the nuts come loose during mid flight but I have had a problem where the nut got stuck and it twisted off the motor shaft when I was loosening it. Those nylon locking nuts that come with the motors don't come loose on their own.
