You can minimise these problems as follows:
1. Fit the servo output arm on the flap and aileron
servos at right-angles to the pushrods.
2. Determine the centre of the working range of the
control surface:
Example: the working range of the control surface
(e.g. flap) is +20° ... -60°, starting from the neutral
position (control surface in line with airfoil)
 the centre of the working range of the control
surface is therefore at -10°.
Adjust the control surface pushrod so that the con-
trol surface is at -10° when the servo is at centre.
 TIP:
When you select the servo in the
Servo / Cali-
brate
menu, select the percentage value for point
P3 and then press the digi-adjustor assign button
<
F
>: the servo will then run to its exact neutral
point (Î 16.1.).
3. Both
FLAP+ and AILERON+ servos should now be
calibrated at points
P1, P3, and P5 (also points P2
and
P4 i f u s e d ) s o t h a t b o t h c o n t r o l s u r f a c e s o n
each side line up exactly at all points (in our exam-
ple at +20° / -10° / -60°).
4. Now adjust the
Off (offset) parameter of the
Spoiler input in the FLAP+ and AILERON+ mix-
ers so that the control surfaces follow the wing air-
foil exactly.
The diagram below shows how this system works in
