Since no one seemed to have an opinion, I thought I'd post the results of my trial/error approach to the problem. The problem was: How do we put an auxiliary device on the aux3 channel and have proportional control in both flight and landing modes? First, having flown with a 347 for 6 years and programmed a 783 a number of times, I'd like to say that Sherman's approach is superior to the one I had used. Second, although there probably is a better way, this is what I did to get the problem solved. Here are the basic steps: set mix 4 to pot5->aux3 rate: +100% +100% SW: on offset +170 set mix 6 to aux3->aux3 rate: +100% 0% SW: btfy1 offset -512 aux3: norm trvl adj aux3 +100% -100% sub trim aux3 -170 Now I can have full inflight adjustment of an "autopilot" or gyro device. The plan is to turn the auto pilot off for thermalling, then when she gets too high to see, dial in the autopilot and head cross country. I also will have a thermal sniffler on board to maximize/minimize flying through lift/sink at speck altitude. Lastly, the plane will have an altimeter watch to measure just how high she gets. This is what happens to some when they've been flying for too long:) Hope you got something from this (even if its just a smile).
