Checking the battery charge of the iPhone
In order to use the AR.Drone under optimal conditions, make sure that your iPhone's battery is fully
charged. A weak or medium battery charge can lead to poorer performance of the AR.Drone
(responsiveness to commands, quality of the video feed, etc.).
Indoor usage
Avoid flying the AR.Drone close to young children, domestic animals or fragile objects.
Install the hull with the guard rings in order to protect the AR.Drone if it collides with another
object.
