Hey All 2-weeks ago, when my P3A,was brand new, after two flights, i noticed that one of the grey props wasnt selftightening til the end. It wasnt going to the fullest. was stopping. So i looked inside, and saw it was damaged from inside a bit, so i decided not to risk and throw it away. Today, when i was attaching props, AGAIN the grey prop had the same issue. Looked inside of it, same kindof "damage". But this one rotates perfectly on one of the motors, but on the second one it gets stuck. So i will dump this one also. Can this be because of overtightening?
