09. Head Free
In this mode, the "head" of the multicopter is always pointing to the same direction as when the feature was activated. This means that when the multicopter rotates around the Z axis (yaw), the controls will always respond according the same "head" direction.With this mode it is easier to control the multicopter, even fly it with the physical head towards you since the controls always respond the same. This is a friendly mode to new users of multicopters and can prevent losing the control when you don't know the head direction.
To work headfree properly, you should not move or turn because drone doesn't know the heading of yourself aTelloPilot can track your heading and can adjust the angle of drone
- Tello doesn't have GPS so it can't provide absolute coordinate
- And it doesn't have compass either so it can't provide absolute its heading
- So alignment is required when it is turned on and flight app is started
- Orientation should be aligned between Tello and yourself when Tello is turned on
- no compass module in Tello, so the orientation is 0 where Tello is turned on
- turn head free on to ignore Tello heading
