Headless Mode
The front and rear positions of a drone are generally indicated by LED lights or colored
propellers. By default, the users are readily able to identify the front and the rear of the
drone when flying. However,under headless mode, the users can operate the drone
without worrying about the orientation (left is left and right is right at all times,
regardless of the direction to which the drone head is pointing ). This mode is designed
for beginners and also the users, who fly the drone in daylight or at a far distance when it
is difficult to identify the drone orientation.
The default setting is NOT Headless Mode.
You are allowed to activate the headless mode function before taking off or in
flight. To fly under headless mode, you are required to ensure that the drone front
direction is aligned to your front direction, DO NOT change the orientation of your
transmitter and keep it in front of you at all times.(See below picture)
WARNING: DO NOT USE HEADLESS MODE BEFORE YOU ARE SURE THAT THE DRONE'S
FRONT IS YOUR FRONT. OTHERWISE, CONTROL MAY BE LOST AND THE DRONE FLIES AWAY.
