Glider with two ailerons
Primary input: Aileron Q ->Q
The aileron input has two values which have to be set.
If you are setting up a new model, the values are set by
default to -100% / 100%, i.e. the aileron travels are the
same up and down. If you wish to set aileron differen-
tial (up-aileron travel greater than down-travel), set two
different values at this point (
Input: Spoiler
If you wish to use raised ailerons as a landing aid or for
a Butterfly (crow) system, you have to dial in this input.
The default setting is 0% (no travel). There is only one
value to enter at this point, as the ailerons only move in
one direction from neutral as spoilers (
Input: Flap
This input is used to alter the camber of the wing airfoil
(e.g. for speed / thermal tasks). The ailerons can be
deflected up and down, so there are again two values
to enter. The default setting is 0%. This value also has
to be dialled in to activate the Flap control (
Input: Elevator
This input alters the position of the ailerons when the
elevator stick is operated, and it can be switched on
and off using the S3 switch (SNAP). The default setting
is 0% for both values. This function is termed Snap-
Flap, and supports the elevator function, e.g. for aero-
batics and when pulling tight turns (F3B) (
14.5.2. Aileron travel and differential
MIXER
Menu: (
In this menu you set the aileron travel in the up and
down directions.
Note: direction of servo rotation
For the following settings we assume that you have
already checked and corrected the direction of rotation
for servos 1 and 5 ( 14.4.1.).

Stick left:

down
If you hold the aileron stick at one end-point, you can
always check the result of any change by observing the
right aileron (servo 5).
In our example the down-travel (-50%) is half that of
the up-travel (100%); this equates to 50% aileron dif-
ferential.
Note: if you have activated flight phases ..
14.8.), there are two values for the Aileron input Q
(
->Q in each of the three flight phases, i.e. a total of
six values.
! In this case please take particular care when enter-
ing the values, otherwise you might forget or overlook
one value. The result could be an unexpected re-
sponse from your model when you switch phases.
14.5.3. Ailerons raised as landing aid
(or ½-Butterfly)
Menu: (
In this menu you set the up-aileron travel which is to
occur when the Spoiler control is operated. Only one
value has to be set here, because the ailerons are only
required to move in one direction from neutral.
Moving to the SP->Q menu:
to MENU,
to MIXER,
to SP->AI,
Move the Spoiler control (stick or right-hand slider) to
the "spoilers extended" position. In section 14.3.4. you
have already determined whether the control has to be
forward or back for this.
You can now set the up-travel using the 3-D digi-
adjustor. Any changes you make can be checked by
watching both ailerons.
The Spoiler input can be set to any value within the
range -200% to 200% in 2% increments. Values above
100% or -100% may only be set if you are operating
the ailerons with an offset (
