ted Switch
(
Function Mode
)
The purpose of the Inver ted Switch Function is to electronically
reverse several control directions to enable you to fly a
helicopter much more easily inver ted. When the inver ted
switch is pulled down, the inverted flight function is switched
ON. When this function is not in use, the display shows INH as
below . If you do not intend to use the inverted function, leave
this operation inhibited.
In the Function Mode, use the UP and DN keys to select Inverted
Switch and access by pressing the UP and DN keys
simultaneously .
Inver ted Flight Of fset V alue
This inver ted point is the throttle position at which no collective
pitch change will take place when the inver ted flight function is
operated. The higher the value, the further the throttle/collective
stick must be positioned toward the full throttle position. The
factor y preset is 5 0%, and it is actually somewhat less than
hover throttle since the inver ted flight function is normally
operated with the stick toward the lower throttle position.
When the inverted flight function is activated, collective, rudder
and elevator operations are reversed automatically
. For inverted
hovering maneuvers, the flight mode switch should be left in the
N, or Nor mal, position. For inverted aerobatic maneuvers, it is
recommended that you set up a pitch cur
ve dedicated to
inver ted flight. This is most often used in conjunction with flight
mode, switch position 2 .
The throttle cur ve is operated as a preset cur ve selected by the
flight mode switch and does not af fect inver ted or normal flight.
Note: The Throttle Hold Function, when activated, has priority
over the inver ted or flight mode switches.
Refer to the illustrations below to understand the of fset values for
inver
ted flight.

fset value is set for 5 0%, the
inver ted flight pitch curve is exactly opposite from the nor mal
pitch cur

3 5%, the entire pitch curve is lower (relative to the control stick)
as shown. Use caution when selecting the correct amount of
offset as an inadequate pitch range could result.
