Servos 6 And 7 As Spoilers / Landing Flaps; Push-Button Fixed Values (Automatic Aerobatics) Menu: ( Contrl ) Fix - Multiplex COCKPIX SX Manuel D'utilisation

Since this switch has three positions, you can use it to
set a speed controller to the following settings: OFF /
½-throttle / full-throttle, for example.
The value for ½-throttle can be adjusted by offsetting
the centre position for servo 4.

14.11.4. Servos 6 and 7 as spoilers / landing flaps

If your model is fitted with airbrakes (Schempp-Hirth
brakes), or if the inboard wing flaps are to be used
exclusively as landing flaps, servos 6 and 7 can be
used to actuate them.
In this application the Spoiler transmitter control needs
to exploit full servo travel (90°).
How to exploit full servo travel:
• Set the following mixer inputs
Q ->F, F ->F, and H ->F (two values in each
case) to 0%. This disables those inputs.
• Set the Offset for servos 6 and 7 to 100% or
-100% in the OFS F menu.
This places the servo neutral positions at one end of
their working range.
• Set the Spoiler mixer input SP ->F to
200% or -200% .
If necessary, you can correct the end-points for servos
6 and 7 in the SERVO TRAVL menu

The FIX function is not available when the C
is used as a Teacher transmitter (TEACHER = 1), as
the FIX button is used as the Trainer switch.
The "Fixed value for transmitter control" function en-
ables the pilot to move the rudder, elevator and ailer-
ons to pre-programmed positions just by pressing the
FIX button.
This makes it possible to fly manoeuvres such as snap
rolls simply by pressing a button. It is also useful for
SAL (Side Arm Launch) HLGs, where the launch set-
tings can be available with a button-press.
The function is programmed in two stages:
• Activating the FIX function
• Setting the values for aileron, elevator and rudder
Notes:
Caution with flight phases
If you have activated flight phases (
are three values for each control surface. The model
could respond differently in each phase. If this is not
desired, all the values must be set identically.
Transmitter controls have no effect
If you have programmed a fixed value and you press
the FIX button, the associated sticks (aileron, elevator,
rudder) have no effect until you release the button.
