I have the DX7 airplane version (with a few helis on it) ...so I'm not as familiar with the heli version.
With this quad,I have found that you have to keep playing around with different radio settings & sooner or later,you'll get it working!
If moving the stick left,then right isn't tripping the motors to start,make sure your throttle trims are at neutral,play around with the
throttle travel & sub trim settings. I have my throttle travel set at 100 H and 100 L...you could try 105 H & 105 L.
I eventually got the motors to start when I set my system throttle sub trim at +3...funny thing is is if I set it at +5 they don't start!
Bottom line...the lights do tell you where the quad is programmed...just play around with the settings till you get it working!
