With many functions, it makes sense not to trigger
their actuation by using one of the normal switches,
but to trigger them automatically by the specifi c, freely
programmable position of a transmitter control or joystick.
Typical applications:
Activation or deactivation of an onboard glowplug •
heating system depending on carburetor setting or
motor speed (in this case, the switch for glowplug
heating is controlled on the transmitter by a mixer)
Switching a stopwatch on or off to measure the

mixer when extending the airbrakes, e. g. so as to

slope when landing on a ridge, without the direction
of fl ight also being affected by the rudder (if the mixer
were active).
Lowering landing fl aps, adjusting elevator trim and/
•
or executing specifi c Dual Rate, Exponential and
Differential switchings when coming in to land, as
soon as the throttle joystick is moved beyond the
switching point. If required, a control switch can be
overridden using a separately assigned switch in the
5th column.
The
mx-20
HoTT program is equipped with a total of
4 of these control switches ("C1" to "G4").
Accordingly, anywhere where switches can be assigned
you have the option not only of using the 9 possible
transmitter switches, but also of choosing and assigning
one of the "C1" … "C4" control switches from the list
of expanded switches – as described in the section
"Assigning transmitter controls, switches and control
switches" on page 52.
Furthermore, combining a control switch with an
additional switch (as described later) also permits more
complex switching permutations.
Basic procedure:
If no transmitter control is assigned, the 1.
corresponding input fi eld in the column above the left
switch icon will be displayed empty.

As an example, the CTRL 6 proportional rotary control
on the upper left is now to be assigned to the "C3"
control switch. Accordingly, turn the dial of this control in
any direction you want. As soon as this is detected, the
control name appears on the display:
