Fly your own drone in the BGE with this model by Dennis Haupt.
Here is a flying drone for the Blender Game Engine.Before you open the blend file and press P to play it would be better if you download Blender 2.72; with an older version of Blender the mouse controls will not work because I've used the new Mouse Actuator for the movement.
Flying drone controls:
Mouse Movement: Rotates the drone and moves the rotors.
Left Mouse button: Drives the drone by a Property.. This Property Affects the acceleration force, the rotational speed of the rotors, the volume and pitch of the sound effect while the Blender Game Engine is running.
Have fun with it :)
