At this point you can set up the direction of operation of
the throttle / collective pitch stick to suit your preference:
press the rotary cylinder briefl y, then use the rotary
cylinder to select the appropriate setting. 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..
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).
Pressing CLEAR sets the collective pitch min. position
to “forward”.
Note:
The Ch 1 trim always affects the throttle servo only. •
By default what is known as the “throttle limiter” is set •
(see page 62); 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 » contr
set. « 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 C3 located on the throttle limiter – can be as-
signed to these two timers in the “timers” line …

… using the switch symbol on the right-hand side. The
assigned switch starts both timers, and also halts the
stopwatch.
The method of assigning a physical switch or a control
switch is described on page 33.
The fl ight timer always starts simultaneously with the
stopwatch, but continues to run even when the stop-
watch is halted (switched off). It can only be stopped by
pressing
ESC with the stopwatch halted.
Once stopped, pressing CLEAR resets both timers to
the initial value.
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 999 minutes and 59 seconds, then re-starts at
0:00.
Count-down timer (alarm timer function)
You can use the left-hand SEL fi eld to select a start-
ing time within the range 0 to 180 minutes; using the
right-hand
SEL fi eld the range is 0 to 59 seconds. Any
combination of times can also be selected.

CLEAR = “0” or “00”.)
