Notice
Do not use the CH6 (helicopter) or CH1 (all other
models) servo reverse option to reverse the con-
trol stick direction. The Thr.HOLD function ac-
tive warning CH1-Pos does not follow this kind of re-
verse control direction. Only use for situation adaptation.
To reverse the control direction, use the FUNCTION
submenu PIT.CRV (page 154) for helicopters models
and THR.CRV (page 128) for all the other model types.
2. Setting the Center Stick Position
The servo middle position is for adapting servos
that are not standard (servo middle position with
a pulse length of 1.5 ms or 1500 μs ) as well as
for minor adaptations, for example fine adjustment
to the neutral position of control surfaces on the
model.
Independent of trim controls and any mix settings,
the center stick position can be shifted around
±125% within the maximum servo travel of ±150%.
The servo is always adjusted independently of all
other trim and mix settings.
Notice
Note that if the neu-
tral position is ad-
justed strongly, ser-
vo travel on one side may
be restricted since the total
travel is limited to ±150%
for electronic and mechani-
cal reasons.
