Note:
If "1 servo" is selected on the "Swash-
plate" line of the »Helicopter type«" menu, this op-
tion is not shown on the multi-function menu.
Use the selection keys of the left or right four-way but-
ton to scroll to the »Swashplate mixer« menu option
in the Multi-function menu:

The number of servos installed in your helicopter for
pitch control was established in the "Swashplate" line
of the »Helicopter type« menu, see page 108. This
information is used to automatically couple together
the functions for roll, pitch-axis and collective pitch,
so that you do not need to define any other mixers
yourself.
For helicopter models with only a single collective
pitch servo, this »Swashplate mixer« menu option is
of course superfluous because the software controls
a total of three swashplate servos for pitch, nick and
roll independently of one another, i. e. without a mixer.
In this scenario, this menu option is therefore no
220 Program description - Swashplate mixer and Fail-safe
longer available to you from the multi-function menu.
With all other swashplate linkages employing 2 ... 4
pitch servos, mixer ratios and mixer directions are set
up by default as shown above. The default is +61 % in
each case but the value can be varied from -100 % to
+100 % if required by briefly tapping the center
key of the right four-way button and its selection keys.
Simultaneously tapping both or selection
keys on the right four-way button (CLEAR) will reset
the mixer ration in inverse video again to the +61 %
default value.
If the swashplate control system (collective pitch, roll
and pitch-axis) does not respond to the sticks prop-
erly, you should alter the mixer directions ("+" or "-")
before trying to correct the directions of servo rota-
tion.
Note:
SET
Ensure that changed mixer values do not result in the
servos mechanically striking their end-stops.

The higher level of operating safety exhibited by the
HoTT system when compared to traditional PPM
technology results from the fact that the microproces-
sor built into the HoTT receiver not only exclusively
processes the signals of "its" transmitter, but can
also clean up "dirty" control signals that it receives.
Only when these signals become too error-prone or
garbled due to outside interference does the proces-
sor automatically replace the disrupted signals with
the last received correct signal, temporarily stored
in the receiver. This feature is configured by the
settings as described below. This feature also sup-
presses brief interference caused by e. g. local drops
in field strength, which otherwise result in the familiar
"glitches". In this case, the red LED lights up on the
receiver.

tings in the currently active model memory, the follow-
