Programming is done in three steps.
First of all, in the "Trim" line it will be established just
which fl ap pair is to be trimmed as "AI" and/or "FL". The
"Control" line specifi es the control channel over which
the given trim function is to be performed and, fi nally,
a switch is defi ned in the "ON/OFF" line by which this
profi -trim function can be switched on or off globally.

Notes:
• Please note that, depending on the number of
aileron and fl ap servos specifi ed in the »Model
type« menu (page 95), some settings cannot
be used. For example, with only 1 aileron and/
or 1 fl ap servo there is no aileron fl ap activation
possible, and the opposite is also true. Since
this is the case, a number of settings in various
columns remain ineffective.
• Pay attention to potential double-assignments
