Trim
Tr. step
... the column "Tr. step" is used to set the increment
size of each "click" on the digital trim keys.
The C1 trimming only affects the throttle servo for the
helicopter. At this point there is no need to go into the
particulars of this trimming ("cut-off trim") once again.
(Thanks to digital trimming, trim values can be saved
automatically when a model change is affected. In
the
mc-32
HoTT system these can even be stored
automatically when a change of flight phase takes
place.).
An additional setting which is specific to helicopters
can also be made in this menu in which you determine
which function the trim slider on the pitch stick should
have. This is accomplished by selecting the "Throttle
limit" setting in the "Throttle" line or leaving it as it is.
This roughly corresponds to trim for the familiar idle
trim function. If the trim indicator marker is moved all
the way forward by "turning" the trim wheel (remember:
"pitch min rear" = "throttle forward") the throttle limit will
later take over the throttle limit for throttle enable seam-

... where input "Tl16" is assigned and all other inputs
are "fr(ee)" by default.
This "Tl16" input serves as the throttle limiter. The
effect of a switch or a control assigned 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 SD1 is assigned
by default, as shown above. As of firmware
version 1103 is the input "Lim." Default "free" and
consequently deactivates the throttle limiter
function. To enable this feature, only needs to
input "Lim." Another donor, for example, the
original proportional rotary slider SD1, are
assigned.
Once again, as a reminder:
•
With the use of the "throttle limiter"
function, you do not have to program a
flight phase "throttle pre-selection".
•
The throttle limiter does not control the throttle
servo; 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 absolutely remain "free". Refer to pages 194
in this manual about this.

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 making 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
