This is my first go round with something other than self tightening props. I have some Tiger Motor MT2212-13 motors and some carbon fiber props. Is there a rule of thumb on how tight I should get the nut on top?
Also, all of my threads are clockwise. Does this matter?
You don't need to go crazy with tightening. I would suggest getting some Nyloc nuts in the appropriate size for your motors. That will eliminate the stress of not having reverse-threaded mounts.
