The free FS8 Viewer software provides easy access to all the setup. The graphics show your finger heat in front of each of the 6 sensors (3 axis) in real time! I used Channel 7 for my remote Co-pilot control. You can set up the Co-pilot on any control surfaces for pitch and roll. The additional "Z" sensor insures that the plane is not inverted in normal Co-pilot Mode and provides pitch control in V-Hover Mode.

For normal Co-pilot Mode, the control surfaces are usually elevator and aileron (or rudder) for pitch and roll. For V-Hover Mode, the control surfaces are normally elevator and rudder. The direction of control is easily reversed in Setup Mode. One 30 second calibration is all you need at the field for both Co-pilot and V-Hover Modes. The infrared sensors cannot be fooled by light. Note that the second image of the Co-pilot setup has V-Hover Mode activated and it says, "Emergency Recovery" because I had the plane sitting against a wall nose down in my office during the setup.

Best of all, the FS8 Co-pilot provides True Failsafe Operation (TFO). In the event of Loss-Of-Signal (LOS), the control surfaces can be set to any pre-determined position (shown as FS in the images). On both my 3lb 3D plane and 23lb 33% Edge 540, I set the motor to off and rudder to full right. The plane slowly descends in a clockwise circle minimizing kinetic energy and impact damage.
