For some reason "and i dont remember any significant crash or tumble before this started " when i hit take off, it moves and angles sharp in the direction of the right rear blade, with very little altitude . I noticed the blade there was bowed with the tips up and that the chassis for the motor, blade, etc would pivot on the rail as well as slide a bit in and out. I super glued the chassis in place and did what i could to straighten the blade but it is still angling and moving hard to the right rear blades direction on takeoff. GOT A CLUE? A SUGGESTION? SOMETHING? ANYONE?
