Warning to anybody putting prop guards on,i put them on my new p3 took it out for three flights and was feeling confident that I didn't need them so when i took them off,the phone rings i answer it then return to my p3 after the call and put the wrong screws back in. The ones that come with the prop guards are longer by about 4 threads and I screwed them in which go right into the windings in the motors. NOT HAPPY with myself!! I stuffed 3 of the motors but have to by 4. So plz be aware i don't want this happening to anybody else.
