Note:
Since this trim function is only effective in the “Motor off”
direction, the illustration above changes if you alter the
transmitter control direction for the collective pitch mini-
mum position of the Ch 1 stick from “forward” (refl ected
in the picture above) to “back” in the “Collective pitch
min.” line of the »
base sett. « menu. In the same way the
effects shown in the illustration swap sides if you change
the stick mode from collective pitch right (refl ected in the
pictures above) to collective pitch left in the “Stick mode”
line of the »
base sett. « menu; see page 50.
collective pitch stick to and fro slightly at the minimum
end-point. When you do this, the throttle servo must not
move! In any case fi ne-tuning must be carried out with
the model fl ying.
The motor is always started with the throttle limiter
completely closed; this has the effect that the idle speed
is controlled solely using the trim lever of the throttle /
collective pitch stick.
Throttle limit in conjunction with the digital trim
When used with the throttle limit control, the Ch 1 trim
places a marker at the set idle position of the motor; at
this point the motor can be stopped using the trim. If the
trim is in its end-range (see screen-shot down in this
column), then a single click immediately takes you back
to the marker, i. e. to the pre-set idle position (see also
page 24).
The cut-off trim only acts as idle trim on the throttle limit
in the bottom half of the travel of the throttle limit control,
i. e. the marker is only set and stored within this range.

For this reason the Ch 1 trim display is also completely
