Please note that on the newer Graupner
and mx remote control systems, the first
pitch servo and the throttle servo are
swapped in comparison to some older systems.

This menu can also be used to adapt travel and direc-
tion for individual servos. However, one must attempt
to retain 100 % servo travel so as to achieve the best
possible resolution and control accuracy. The direction
of travel is determined with "Rev." and, in the process,
make sure that the direction is correct. The tail rotor
servo must run so that the nose (!) of the helicopter fol-
mc
lows the tail stick direction.

... of the mc 20 HoTT transmitter the column "Tr"
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.
Please read more about this on page 62. (Thanks
to digital trimming, trim values can be saved automati-
cally when a model change is affected. In the
HoTT and HoTT systems these can even
mc-20
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 deter-
mine which function the trim lever on the pitch stick
should have. This is accomplished by selecting the
"TL" setting in the "Thr(ottle)" 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 lever (remember:
"pitch min rear" = "throttle forward") the throttle limit will
later take over the throttle limit for throttle enable seam-
lessly in the menu ...
