What do you think you are locking it to?
Most copters already have one rotor locked to the motor stick and the other free. If you lock the free rotor, the motor is locked and everything stops.
The other common double rotor design has two free rotors. Lock one to the motor stick and then you revert to the first case and just spin up the motor stick.
