Headless Mode:
The functioning of headless mode is pretty simple. The only pre-requisite is that before taking off, you're
required to position the drone in such a way that its front is your front. Since yaw (the left stick) anyway doesn't
have anything to do with orientation (left is left and right is right all the time, regardless of where your drone is
pointing at), it is how the drone reacts to rudder (the right stick) that changes. In other words, even when you
turn your drone 90 degrees to the left.
