I have setup my Cortex on a 3 position switch. OFF, then bank 1 = all (Ail,Elev, Rud) in NORM mode, and Bank 2 = Ail and Elev NORM and RUD in HOLD. I only use Bank 2 for takeoff or landing in a crosswind...it's helps with directional control. I agree with those that have mentioned that there is no real practical use for HOLD mode on a jet - its a 3D hovering type of function. If unfamiliar with gyros most people would find the feeling of HOLD mode really strange on a jet and need to bail out quick. Of course the other option I use in Bank 2 is = Ail and Elev NORM and Nose-wheel Steering in HOLD. This allows accurate runway tracking.
