Time delay for the throttle limiter
To safely prevent the carburetor from opening too
rapidly, assign the throttle limiter input "Tl16" to a
time delay that takes effect only in the direction of full
throttle. This applies especially if the throttle limiter is
controlled by a switch rather than, as preset, with the
right-side proportional rotary slider.
To set a delay time, push the throttle limit control to
its forward limit or move the switch into its full-throttle
position then use the selection keys of the left or right
touch pad to select the "–time+" column.

behavior of the throttle limit control such that the latter
provides suffi ciently sensitive regulation of the idle
setting and can also stop the motor.
In this case, with a completely closed throttle
limiter – in contrast to the previously described
setting – use the »Control adjust« menu set the "-"
side of the column labeled "- travel +" for the "Tl16"
behavior of the throttle limit control such that the latter
provides suffi ciently sensitive regulation of the idle

line such that the throttle 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, page
98, 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.
The value for the plus side of the "- travel +" column
should be increased, as described before, to +125 %
so that the full-throttle position of the throttle servo is
also reliably released from the throttle limiter.
Finally, set an asymmetrical time delay of, say
4.0 seconds, so the motor also picks up speed
gradually even if the side proportional slider is pushed
forward too quickly. Select the time preset to correlate
to how far the carburetor opens up at the minimum
collective pitch position. The value set is to be
optimized by testing.
