I recently crashed my Q500+ and broke the arm for the number 4 motor. I purchased a new air frame and am in the process of transferring the components from my crashed Q500+ to the new air frame. Two questions: is there a trick to installing the rubber motor dampers. I've been trying for the past hour with no success. Secondly, when I connected my crashed Q500+ to the GUI, it indicated that all four ESC's had failed. The impact broke all four propellers but the motors test good. Do the ESC's typically not survive this type of crash? I hate to buy four ESC's if I don't have to.
