In the “Collective pitch min.” line you can set up the
direction of operation of the throttle / collective pitch
stick to suit your preference. This setting is crucial to the
correct operation of all the other options in the helicopter
program which affect the throttle and collective pitch
functions, i. e. the throttle curve, idle trim, tail rotor mixer
etc.
Briefl y touch the central
SET button of the right-hand
touch-key, and the direction of operation of the throttle /
collective pitch stick is highlighted. Now you can select
the required variant using the arrow buttons of the right-
hand touch-key:
Pitch
The meaning is as follows:
“front”: minimum collective pitch when the collective
pitch stick (Ch 1) is “forward” (away from you);
“rear”: minimum collective pitch when the collective
pitch stick (Ch 1) is “back” (towards you).
Simultaneously pressing the
cd
or
ef
buttons of
the right-hand touch-key ( CLEAR ) returns the collective
pitch min. position to “rear”.
Note:
The Ch 1 trim always affects the throttle servo only. •
By default what is known as the “throttle limiter” is set •
(see page 79); this limits the travel of the throttle ser-
vo in the direction of maximum throttle, acting sepa-
rately from the collective pitch servos. This point can
be programmed using the “
Lim ” input in the “ Trans-
mitter control settings ” menu.
Timers
Two timers are shown in the basic display: one stop-
watch and one fl ight timer.

A physical switch or a control switch - e. g. the control
switch G3 located on the throttle limiter - can be as-
signed to these two timers in the “Timers” line …

… using the switch symbol at the bottom right-hand
side of the screen. The assigned switch starts both tim-
ers, and also halts the stopwatch.
The method of assigning a physical switch or a control
switch is described on page 39.
The fl ight timer, and the saving of telemetry data on a
memory card inserted in the card slot (see page 22)
always starts simultaneously with the stopwatch, but
continues to run even when the stopwatch is halted
(switched off). It can only be stopped by touching the
central
ESC button of the left-hand touch-key with the
stopwatch halted.
Once stopped, both timers can be reset to the initial
value by simultaneously touching the
cd
buttons of
the right-hand touch-key ( CLEAR ).
Switching between “count-up” and “count-down”
Count-up timer (stopwatch function)
If you assign a switch and start the stopwatch with the
initial value of “0:00”, the timer runs up until the maxi-
mum of 180 minutes and 59 seconds, then re-starts at
0:00.
Count-down timer (timer function)
In the left-hand minutes fi eld you can select a starting
time within the range 0 to 180 minutes; in the right-hand
seconds fi eld the range is 0 to 59 seconds. Any combi-
nation of times can also be selected.
Simultaneously pressing the
cd
buttons of the right-
hand touch-key ( CLEAR ) resets any settings you have
entered to “0” or “00”.
