Notes:
•
Please note that, depending on the number of ai-
leron and flap servos specified in the »Model
type« menu, page 105, some settings cannot
be used. For example, with only 1 aileron and/or 1
flap servo there is no aileron flap activation possi-
ble, and the opposite is also true. Since this is the
case, a number of settings in various columns re-
main ineffective.
•
Pay attention to potential double-assignments
when making trim control choices.
The trim functions which can be activated (ON) or
deactivated (OFF) on the first line of this menu, either
