The lower rotor has a problem where the gear on the motor shaft slides down and does not engage with the rotor gear. You can reach in through the skeleton with a small screwdriver and push the gear back up to engage. Happens every now and again, usually after a crash.

I would assume the batteries are charged? If they are maybe they just will not hold a charge anymore. You may have to get new ones.
