i crashed my qr-1 into a door frame. not too hard. nothing that hasnt happened a lot before anyway.
and when i tried to take off for the first few times only 2/4 or 3/4 motors would run, obviously wouldnt fly.
but i can pick it up, and can move the throttle up/down back/fourth a little and get them to straighten out. any ideas on whats goin on?
