The Inspire 1 Propeller Lock is designed to secure the 1345 propellers in place during flight. Installation Demonstration: 1. Tighten the propellers on the motor by hand, and ensure they are securely mounted. 2. Align the tips of propeller lock with the ventilation holes on the motor and slide the propeller lock onto the nut of propeller. 3. Press the propeller lock against the motor firmly, and installation is complete. Examine to ensure the propeller lock is tight on the motor before each flight. Removal: Squeeze the tips of the propeller lock to release, twist the propeller lock obliquely to separate it from the motor. After removing, store the propeller locks in a safe place for future use. Notes These Propeller Locks will become available next Monday. If you ordered your Inspire 1 from the DJI Online Store, they will automatically be shipped to you. If you purchased your Inspire 1 at an authorized DJI dealer, you can collect them there. DJI recommends that you do not attempt flying your Inspire 1 before receiving and installing the Propeller Locks. If you have to fly your Inspire 1, please ensure the propellers are securely mounted before each flight.
