2. REMOTE CONTROL OVERVIEW

Place the quadcopter 2 metres in front of you with the nose facing away from you, after lift off, long press the Headless
Mode button for over 2 seconds to enter Headless Mode. Long press the Headless Mode Button for over 2 seconds to
exit Headless Mode.
Headless Mode allows the quadcopter to operate in such a way so that the orientation remains in its initial state, no
matter which way the quadcopter is facing at the time. For example, if the quadcopter lifted off facing the front (facing
away from you) and then turned 90° to the left, when entering Headless mode, the quadcopter is going to assume its
now right side as the front, so if you push forward, the quadcopter is going to move forward (facing away from you),
rather than to the left.
Headless mode makes it easy for beginners to control the quadcopter when it is difficult to establish the orientation, and
it is an easy way for you to retract the quadcopter, simply push backward, and the quadcopter will fly towards you.
