Do you Wax your Drone / props /controller?

No I would never add any chemical to my props as most will break down plastic and also make them off balance. There is no need what so ever to wax any part of your UAV.

 

The only thing I do as far as cleaning any of my UAV's is to use a micro fiber cloth to wipe off the dust.
On a occasion I also use compressed air to blow out the motors, but I don't do that very often and take care when doing so. I usually only do that if I have been flying in a dusty area or see some type of debris in a motor.
