Someone replied on another forum that they suspect either the motor shaft or the gear shaft is bent after the crash. That makes a lot of sense - the gear spins freely for part of the rotation (where the gear shaft is bent away from the motor gear), and then sticks for part of the rotation...
Hey guys, I get that this is an incredibly noobie question, but I'm hoping someone can help me anyway. I just received and flew my first quad, a Holy Stone HS110W. It's a pretty basic drone, but I think it would've been a decent one... had I not failed to attach the rotor guards and crashed it...
