Hey TECHS I have been online to see what the corrective action to fix my P4 was and yall haven't replaced the motor... I cant remember which one but all you have to do is put a blade on and hand spin it and there is a terrible grinding noise that resonates throughout the copter...Can you fix this before I have to send it right back?

CAS-251779-T1J9Q2
