Note:
If "1 servo" is selected on the "Swashplate" line on the
"
Helicopter type " menu, this option is not shown on the
multi-function list.
On the "Swashplate" line on the "Helicopter type"
menu, you have already defi ned the number of servos
that are installed in your helicopter for collective pitch
control; see page 86. This information is used to
automatically couple together the functions for roll,
pitch-axis and collective pitch, so that you do not need
to defi ne any other mixers yourself.
If you have a model helicopter which only has a
single
collective pitch servo , this "Swashplate mixer" menu
option is of course superfl uous, since the software
will control the three swashplate servos for collective
Swashplate mixer
Collective pitch, roll, pitch-axis mixer
pitch, pitch-axis and roll independently of one other,
i.e. without a mixer. In this scenario, this menu
option is therefore
no longer available to you from the
multi-function list. With all other swashplate linkages
employing 2 … 4 collective pitch servos, the mixer ratios
and directions are set up by default, as can be seen
above. The preset is +61% in each case, but the value
can be varied from -100% to +100% if required, by
briefl y tapping the center
SET key on the right touch pad
and using the arrow keys.
Simultaneously tapping the two arrow keys

or

on the right touch pad ( CLEAR ) will reset the mixer ratio
in the highlighted fi eld back to its default value of +61%.
If the swashplate control system (collective pitch,
roll and pitch-axis) does not respond to the joysticks
properly, you should alter the mixer directions ("+" or "-")
before trying to correct the directions of servo rotation.
Note:
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 microprocessor
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 processor
automatically replace the disrupted signals with the
