Disorientation:
During flight if you get disorientated, do not panic. But leave the sticks to center and switch to GPS position hold mode.
Quad will hold its position. Try to figure out if Quadcopter is facing away for facing to you, you can use Channel 4 (rudder)
to yaw and see if you can figure out quadcopter rear or nose. It will be easier for you to fly it back if you re-establish
orientation.
Normally it is easier to find qudcopter rear, due to rear LEDs on the Quadcopter. In case you are too far, and can’t
designate rear from front, then simply switch on IOC and now you can easily use Elevator and Aileron channels and bring
the quadcopter back to you. Once you re-establish your orientation you can turn IOC off and start flying in normal mode.
The easiest way in such situation when you lost orientation due to quadcopter flying two far for your eyesight, is to
activate the Auto return to home feature.

check the gains settings using assist program for FreeX.
