Hi all, am new to this site and quad flying, I have recently purchased a XK ALIEN X250, have been out once with this,and think as a first time quad it does not disapoint.The only thing that is wrong with this quad is the instruction manual, which is translated from Chinese to English, try as I might I cannot make any sense of the instructions for turning on the headless mode, can anyone explain how to do this, thanks in advance.
