With a simultaneous tap on the 
ef keys of the left 
touch pad, the setting can be checked in the »Servo 
display
«.
Since the C1 control should actuate Servo 8 
simultaneously with Servo 1, establish this link by 
way of the »Control adjust« menu.
For this reason, also switch to the line before and 
assign "Control 1" to Input 8.

However, please note in this connection, that a non-
linear control curve programmed in the »Channel
1 curve
« menu has as little effect on this input as 
brake offset set to less than 100 %, which you can 
check very easily in the »Servo display« menu. 
You can reach this from nearly every menu position 
with a simultaneous tap on the 
ef keys of the left 
touch pad:
The travel, and if applicable also the direction of 
rotation, for spoiler servo 1 as well as the second 
spoiler servo connected to Output 8 can be adjusted 
in the menu …

cAI
determines the percentage share with 
which the two fl ap pairs "AI" and "FL" are 
to respond to aileron steering. Also check 
whether the ailerons are defl ected in the 
right direction during the adjustment of the 
parameter values.
 
The adjustment range from -150 % … 
+150 % enables the correct throw direction 
adjustment regardless of the direction of 
rotation of the servos.
AI-Tr.  
determines the percentage share with which 
aileron trimming should effect the AI and FL.

the entry to specify aileron steering 
differentiation
 for AI and FL fl aps is 
made here. Refer to page 161 about the 
signifi cance of differentiation.
 
The adjustment range from -100 % … 
+150 % enables the correct differentiation 
direction adjustment regardless of the 
direction of rotation of the aileron and fl ap 
servos.
FL-Pos.  The fl ight-phase specifi c positions for all 
camber fl aps present on the given model 
are set in this line. In the process, you can 
determine the positions the fl aps assume 
for each fl ight phase.
Note:
The values appearing in this line are based 
on the same data set as in the comparable 
position in the »Phase trim« menu, which 
is why changes always take effect in both 
directions.
cFL
Since all inputs in the »Control adjust«
menu are set to "free" by default, neither 
the ailerons nor the camber fl aps can be 
operated with these default settings. In this 
respect, you also leave the default entry here.
 
However, if fl ap positions are to be varied 
with a switch or proportional control by 
the position specifi ed in the "FL-Pos." line, 
assign the desired control to Input 6 in the 
»Control adjust« menu and set the desired 
reaction to the movement of the control 
selected for this purpose by way of 
a percentage in this line.

¼WK this mixer induces a partial reaction from 
aileron (AI) and camber fl aps (FL) during 
elevator activation.
