Rob, had the same problem. Here is what I got when I called Horizon. The manual is incorrect.

Addendum to 8103 Program for Ultra Stick:

1. Go to function list
2. Highlight D/Flap T. and hit enter
3. Activate Pot 6
4. Return to function list
5. Put your 3 position flap switch in the bottom position
6. Select Program mix 5 or 6 (whichever is empty)
7. Set flap pot at full negative value
8. Select Offset and press "clear/store" (value should be –222)
9. Go back to function list
10. Select D/Flap T.
11. Set pot 6 to "inh"
12. Return the flap switch to the top position
13. Go to your flap mix and set the rate until your ailerons are level
14. Have fun flying your Ultra Stick!
