Trex 250 Main wont Spin

This is a new issue to me. After a minor ground strike and repairs the main rotor doesnt spin but the tail spins fine. IM thinking the one way bearing in the main gear is shot? Do they do that? All gear teeth are intact. Manual turning behaves the same.
Thanks

If you hold the head and try to thumb spin the maingear clockwise, it should not move. If it does your one-way bearing is blown. Yes, they do blow out with a blade strike or just from a lot of flights.
