... where input "Lim." is assigned and all other inputs
are "fr(ee)" by default.
This "Lim." input serves as the throttle limiter. Its
effect is exclusively on output "6", where the throttle
servo is connected. The throttle limiter is assigned by
default to the right-side proportional rotary control.
• In firmware versions up to and including
1102 the throttle limiter to the right side
proportional rotary slider SD2 is assigned
by default, as shown above. As of firmware ver-
sion 1103 is the input "Lim." Default "free" and
consequently deactivates the throttle limiter func-
tion. To enable this feature, only needs to input
"Lim." Another donor, for example, the original
proportional rotary slider SD2, are assigned.
Once again as a reminder:
• With the use of the "throttle limiter" func-
tion, you do not have to program a flight
phase "throttle pre-selection".
• The throttle limiter does not control the throttle ser-
vo; it only limits the travel of the throttle servo in
the full throttle direction according to its position.
The throttle servo is generally controlled from the
pitch stick via »Helicopter mixer« menu setting/s
for throttle curve/s, which is why input 6 must ab-
solutely remain "free". Refer to pages beginning
on page 188 in this manual about this.
• The C1 trimming also affects only the throttle ser-
vo for the helicopter. At this point there is no need

In doing so, it is assured that the throttle limiter re-
leases the entire throttle travel with the pitch stick later
during flight.
Adjustment notice for electric helicopters:
Since electric drive systems have no need for
an idle setting, the basic configuration of
settings for an electrically-powered helicopter
merely involves ma king sure that the control range of
the throttle limiter is both higher and lower than the
adjustment range of the speed controller (usually
-100 % to +100 %) by a safe margin. If necessary,
therefore, the adjustment of the "travel" setting of the
throttle limiter described above must be modified
accordingly, for example, to symmetric +110 %. The
further adjustment, however, can take place analo-
gously to the combustion helicopter described here.
With this process, you have carried out the basic set-
tings for the transmitter as they are needed again later

a switch to the corresponding sub-menu. The graphic
