GRAUPNER MC-32 Manual page 147

Typical applications:
• On/Off switching of an on-board glow plug in
conjunction with the carburettor setting and/or
motor speed. (The glow plug heater switch for this
will be controlled by a transmitter-side mixer.)
• Switching a stopwatch on or off to measure the
simple running time of electric motors
• Automated switch-off of a combi "aileron  rudder"
mixer when extending the airbrakes, e. g. so as to
match the bank attitude of the model to the ground
slope when landing on a ridge, without the direction
of flight also being affected by the rudder (if the
mixer were active).
• Lowering landing flaps, adjusting elevator trim
and/or executing specific Dual Rate, Exponential
and Differential switchings when coming in to land,
as soon as the throttle stick is moved beyond the
switching point. If required, a control switch can be
overridden using a separately assigned switch in
the 5th column.
mc-32
The HoTT program is equipped with a total
of eight so-called control switches ("C1" to "C8").
Accordingly, anywhere where switches can be as-
signed you have the option not only of using the 16
possible transmitter switches, but also of choosing
and assigning one of the "C1" ... "C8" control switch-
es from the list of expanded switches – as described
in the section "Assigning transmitter controls, switch-
es and control switches" on page 60.
Furthermore, combining a control switch with an ad-
ditional switch (as described later) also permits more
complex switching permutations.
Basic procedure:
1. If no transmitter control is assigned, the
corresponding input field of the column labeled
SEL (second column from the left) will be empty.
2. Use the selection keys of the left or right touch
pad to select the line for the desired control switch
(1 to 8).
SET
3. Briefly tap the centre key of the right touch pad.
4. Move your selected transmitter control.
The associated transmitter control number
appears in the input field of the column above the
left switch icon.
5. Use the selection keys on the left or right touch pad
to move to the right into the column labeled STO.
6. Move the transmitter control to the desired switching
point then briefly tap on the centre
right touch pad to save the switching point.
7. Complete the remaining settings such as switching
direction, etc.
8. Exit from the menu with a tap on the centre
key of the left touch pad.
Assigning a transmitter control to a control switch
Using the selection keys on the left or right touch
pad, select your chosen line (1 to 8). Following a final
tap on the centre SET key of the right touch pad to
activate the control assignment, the message shown
below will appear in the display:
C O N T R O L S W I T C H
C1 frei 0%

C2 Geb. 1 0%

C3 free 0%
C4 free 0%

For example, the right-side proportional slider is now
to be assigned to control switch "C1", the default
throttle limiter for a helicopter model memory.
So just move this control in any direction. As soon
as this is detected, the control name appears on the
display:

Move the selected transmitter control to the position
