Chosen Solution

Recently crashed my drone (not TOO hard), and it landed upside down. Since then, everything works except for one of the motors. It can spin if I put some force, but the motor seems to be jammed. When I attempt to fly the drone, the prop doesn’t spin at all, but the other 3 do.

Guessing you need to replace one of these? http://www.bayangtoys.com/index.php/baya
