Update and request resolved -
You saved me countless hours/days to accomplish this task - Thank you Andy!
-Using a DX8 G2 and updating firmware to 2.05 as you suggested
-Imported the DX9 file you provided
-AR610 with all six ports occupied
-Sw harness in bind/data port
-Channel assign: RUDD L Elev and AUX1 Left Ail
-Three servos reversed
Perhaps because of my setup technique, I did change Mix 1 to RAL and after a few head scratching moments because the left elevator wouldn't reverse during changeover, a little research from Lake Sawyer Hawks website during lunch gave me an idea to simply swap elevator servos around and now it works properly in both conditions! Yay!
Just a little tweak I'd like to perform; rates are set at 50% with the throttle mix - can I increase these to 100% without consequence?
