Using the VEX AIR Drone Propeller Lock

The VEX AIR Drone’s Propeller Lock is an important safety feature that helps ensure safe drone operation. When the Propeller Lock is engaged, it prevents the motors and propellers on the drone from turning. All flight commands are ignored, and the LEDs on the Drone and Controller will blink blue. This Propeller Lock feature is exclusive to VEX Drones and was designed specifically for education and competition situations.

While the Propeller Lock is active:

• The motors and propellers cannot start for any reason.

• The default_fly project and other projects can be started, but all flight commands will be ignored.

• Projects can still access Range Sensors, Inertial Sensors, Vision data, module controls, controller inputs, and controller screen commands.

Propeller Lock activation

The Propeller Lock activates automatically, and can also be activated manually.

Automatic activation

The Propeller Lock will activate automatically when the drone detects handling. Automatic activation is available while the drone is linked to a controller and its propellers are not already spinning. Drone handling that triggers the Propeller Lock includes picking up, tilting, carrying, or changing a Mission Module.

Manual activation

The Propeller Lock can also be activated manually by pressing the Propeller Lock Button on the controller. Manual activation is available while the drone is powered on, connected to a controller, and not in flight.

Deactivating the Propeller Lock

To deactivate the Propeller Lock, the drone should be placed in a safe, level takeoff area. Press the blinking blue LED Power Button on the drone. The LEDs on the drone and controller will return to red, green, or yellow depending on the current battery level. Now default_fly or other projects can be used.
