Using headless mode

One thing that gets me confused is the controller it is so easy to get in a muck and fuddel so i have tried the Headless mode and hope that keeps the bloody thing out of the trees.

Headless Mode

first  how dose a quad-copter work, on a very general level. Like any vehicle, the quad-copter has a front and a back, but with a design that’s is symmetrical that it’s tough to make out between the front and rear. To solve this problem, many quad-copter makers ship their quad-copter with propellers that are color co-ordinated; for example, red propellers on the front and black on the rear (and so on).

However, once the quad-copter is a certain distance away from you, it is impossible to tell between the colors, which again gives us the problem of orientation. Some manufacturers supply LEDs on drones which really help, but then again these LEDs are pretty ineffective in daylight.

Headless mode is basically a method implemented on a quad-copter that allows you to give up worrying about orientation altogether.

Headless mode is pretty simple. The only important step is that before taking off, you’re required to point the quad-copter in such a way that its front is your front. Since yaw (the left stick on a Mode 2 controller) anyway doesn’t have anything to do with orientation (left is left and right is right all the time, regardless of where your quad-copter is pointing at), it is how the quad-copter reacts to rudder (the right stick on a Mode 2 controller) that changes.

When you take off with the quad-copter pointing in the front,  programs inside of the quad-copter’s micro-controller ensure that any directional change is compensated. In other words, even when you turn your quad-copter 90 degrees to the left, it’ll still go forward when you push the rudder forward (on a non-headless mode quad-copter, this would make the quad-copter go left).
