Program description - Control adjust | Helicopter models
• A servo connected to output 16 can be used,
independently of this, for other purposes by
means of mixers, provided that this servo is
decoupled from the operating element specied by
function input 16 via the »Mix only channel«
menu; see page 221.
• The throttle restriction set by the throttle limiter
is shown as a horizontal bar in the throttle
curve diagram on the second display page
of the "Channel 1  Throttle" option in the
»Helicopter mixer« menu (see page 194).
The output signal for the throttle servo cannot be
higher than the level set by the horizontal bar:

Throttle
The above diagram shows precisely this scenario:
in the above example, the throttle limit control
is set to about -60 % and thus restricts the
movement of the throttle servo to about -60 % of
full travel.
Time delay for the throttle limiter
To safely prevent the carburettor 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.
