At SETUP MENU point M we can limit the servo movement so that the servos will not come out of the possible range of action and cause jamming of the linkages or swashplate. But ideally we want to limit as less as possible, so that the system can control the helicopter without any restrictions! For the ease of use, the limiting is only one value to adjust but which will affect all servos and all possible directions at once, especially when steering into the corners.

The color of the Status LED gives some indication whether you rotorhead geometry is well suited for flybarless usage or not. Ideally the Status LED on the device should be blue after you've adjusted the limit properly. If it isn't, this means your servos do not make very large deflections and probably you do not have very much cyclic pitch left in the extreme positions. This can for example cause pitching up when flying with high speed and lots of collective input, inprecise flying in general or it can cause you heli not to have equal rotations rates, accelerate slowly or not being able to reach high rotation rates at all.

purple	not good
red	OK
blue	perfect!
