(Main-) Rotor direction
In the »rotor direction« line you enter the direction of ro-
tation of the main rotor using the right-hand rocker but-
ton, after pressing
SELECT :
„right“: the main rotor rotates clockwise as viewed
from above.
„links“: the main rotor rotates anti-clockwise as view-
ed from above.
CLEAR switches to “left”.
The program requires this information in order to set up
the mixers to work in the correct “sense”; this applies to
the mixers which compensate for rotor torque and motor
power. You will fi nd these in the »
Heli mixer « menu:
Collective pitch
Channel 1 throttle
Channel 1 tail rotor
Base settings – model helicopter
Collective pitch min.
At this point you can set up the direction of operation of
the throttle / collective pitch stick to suit your preference:
Press
SELECT , then use the right-hand rocker button to
select the appropriate setting. This setting is crucial to
the correct operation of all the other options in the he-
licopter program which affect the throttle and collecti-
ve pitch function, i.e. the throttle curve, idle trim, tail ro-
tor mixer etc..
The meaning is as follows:
“front”: minimum collective pitch when the collective
pitch stick (C1) is in “front” (away from you);
“rear”: minimum collective pitch when the collective
pitch stick (C1) is “back” (towards you).
Pressing CLEAR sets the collective pitch min. position
to “front”.
Note:
• The C1 trim always affects the throttle servo only.
• By default what is known as the “throttle limiter” is set
(see page 54); 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 » Control
settings « menu.
Clocks
Two timers are shown in the basic display: one stop-
watch and one fl ight timer.
A physical switch or a control switch can be assigned 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 25.
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.
