Swashplate rotation can be set to +/- 45°. The prefix
indicates whether the set rotation is in the clockwise
or anti-clockwise direction.
COLL MIX is an auxiliary mixer (see below).
COLL MIX

The auxiliary mixer COLLECTIVE PITCH MIX links
the five possible COLLECTIVE PITCH CURVES. This
auxiliary mixer must be assigned to all swashplate
servos, since - as already mentioned - all the swash-
plate servos are responsible collectively for
COLLECTIVE PITCH movements.
If you assign this mixer to one servo (e.g. servo 12)
and then attempt to adjust the servo in Menu 1, the
following message appears:

This informs you that no adjustments are possible for
this mixer at the servo end of the system. Changes
can only be made in the COLLECTIVE PITCH
CURVES in Menu 1: Transmitter control adjustments.
Of course, different curves can be set up for all five
flight modes.

If your helicopter is equipped with HEIM mechanics,
the mixer you need for the servos looks like this:
1
ROLL
2
COLL MIX
ROLL stands for „virtual“ ROLL. That means that with
these inputs the system is already prepared for „vir-
tual“ rotation of the swashplate. Swashplate rotation is
set in the transmitter control menu for ROLL.
COLL MIX is an auxiliary mixer (see HEAD-MIX
above for a description).

You would set up this tail rotor mixer if you need to
provide a corrective tail rotor movement to counteract
motor torque. This mixer has five inputs which come
from the COLLECTIVE PITCH transmitter control in
the form of TAIL ROTOR curves.
To control the tail rotor you also need to add the YAW
input. We have already described how this is done in
the „UNIVERSAL Helicopter“ section.

The throttle mixer has four inputs, and the HELI-
throttle input is linked to the throttle curve and idle-up.
The throttle curve can be set for each flight mode
individually in the COLLECTIVE PITCH transmitter
control menu.
1
HELI-THR
2
ROLL
3
PICH-AX.
4
YAW
You can use inputs 2, 3 and 4 in order to apply slightly
„more throttle“ automatically when you give ROLL,
PITCH-AXIS or YAW commands. This meets the
need for increased energy which arises when you give
a ROLL, PITCH-AXIS or YAW command. The link to
COLLECTIVE PITCH is set in the THROTTLE
CURVE menu, and is passed to the throttle servo via
the mixer input HELI-THROTTLE.
HELI-THROTTLE is an auxiliary mixer (see below).
NFQA/DNE
. auxiliary mixer
This mixer has the following three inputs:
1
DIR. THROT
2
FIXED VAL:
3
COLL PITCH
If you assign a switch to DIRECT THROTTLE when
setting up the COLLECTIVE PITCH control, this func-
tion alone controls the throttle when activated. When
DIRECT THROTTLE is switched on the other two
inputs have no effect.
FIXED VALUE becomes effective when you switch to
the flight mode AUTO-ROTATION. The other two
inputs then have no effect.
COLLECTIVE PITCH comes into effect if neither
DIRECT THROTTLE nor AUTO-ROTATION is
switched on. This input conceals the TAIL ROTOR
curves generated by the COLLECTIVE PITCH control,
which are also adjusted at that point.
