HELI 83
The purpose of the Inverted Switch Function is to electronically
reverse several control directions to enable you to fly a
helicopter much more easily inverted. When the inverted
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.
Inverted Flight Offset Value
This inverted point is the throttle position at which no collective
pitch change will take place when the inverted flight function is
operated. The higher the value, the further the throttle/collective
stick must be positioned toward the full throttle position. The
factory preset is 50%, and it is actually somewhat less than
hover throttle since the inverted 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 Normal, position. For inverted aerobatic maneuvers, it is
recommended that you set up a pitch curve dedicated to
inverted flight. This is most often used in conjunction with flight
mode, switch position 2.
The throttle curve is operated as a preset curve selected by the
flight mode switch and does not affect inverted or normal flight.
Note: The Throttle Hold Function, when activated, has priority
over the inverted or flight mode switches.
Refer to the illustrations below to understand the offset values for
inverted flight.
As shown above, when the offset value is set for 50%, the
inverted flight pitch curve is exactly opposite from the normal
pitch curve settings. If the offset is adjusted to a lesser value, say
35%, 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.
