I tried flying my Exceed rc Falcon 40 and the main rotor doesnt spin. I noticed earlier I turned off the radio before unplugging the battery from the helicopter and I'm wondering if that did it. The tail rotor spins but I don't know what to do. Does anyone have any tips on what the problem may be. I've had this heli for some time now and still can't get it off the ground. I'm about ready to just sell the damn thing. Any help would be greatly appreciated.
