… makes the digital trim of the throttle/collective pitch
stick active only in the "Autorot" fl ight phase. As a result,
in "normal" fl ight phases, the C1 trim lever can be used
neither to control the motor's idling nor to stop the motor.
To ensure you still retain suffi cient adjustment options,
we recommend using "Expo throttle limit" here.
This sub-menu for this is found on the menu …

… and the exponential curve characteristic it confi gures
can adjust the control characteristics of the throttle limit
control so that the latter provides suffi ciently fi ne control
of the idle setting and can also stop the motor.
In this case you should turn the throttle limiter fully to
the left – unlike the previously described setting on the
"Control adjust" menu – and adjust the "–" side of the
"–travel+" column in the "Th.L.12" line so the throttle
Throttle limit in conjunction with "Thr AR" on the "Stick mode" menu
limiter fully closes the carburetor, i.e. the motor is safely
switched off at this control position.
Following this, move the throttle limit control to its center
point and change the % value of the "Expo thro lim." line
in the "Helicopter type" menu (see page 86) until the
carburetor is in a position suitable for starting the motor.
Now start the motor, and adjust the value if necessary
until the motor idles reliably in this throttle limit control
position.
For the plus side of the "–travel+" column, increase the
value to +125% as described before, so that the full-
throttle position of the throttle servo is also released
reliably by the throttle limiter.
Finally, set an asymmetrical time delay of, say,
4.0 seconds, so that the motor also picks up speed
gradually even if you move the proportional rotary
control too quickly to the right. Select the time preset
to correlate to how far the carburetor opens up at the
minimum collective pitch position. The value you set will
need fi ne-tuning by practical testing.
