Mixing rate setting procedure
The HR3 swash-plate type will be used as an
example to describe mixing rate setting. The mixing
used in other swash modes may be different,
however, the setting procedure is the same.
*Set the throttle stick to the preset neutral point. Adjust the
length of the linkage rod so that the swash plate is horizontal
at this position.
*The sub-trim function can be used to make small
adjustments.
*Adjust so that the pitch curve is a straight line and the
helicopter achieves maximum pitch.
*Move the cursor to the item you want to adjust and touch
the RTN button to switch to the data input mode. Touch
the RTN button to end adjustment and return to the cursor
mode.
1. Adjusting the aileron operation [AIL to PIT]
Adjust the AIL to PIT rate so there is no binding
in the elevator or pitch movement when the
aileron stick is moved to the left and right.
*Adjust by scrolling the touch sensor.
*The left and right sides can be adjusted individually.
2. Adjusting the elevator operation [ELE to AIL]/
[ELE to PIT]
Adjust the ELE to AIL and ELE to PIT rates so
there is no binding in the aileron or pitch
movement when the elevator stick is moved
up and down.
*Adjust by scrolling the touch sensor.
*The up and down sides can be adjusted individually.
3. Adjusting the pitch operation [PIT to AIL][PIT
to ELE]
Adjust the PIT to AIL and PIT to ELE rates so
that the swash plate moves to the level/
horizontal position when the throttle stick was
moved to maximum low and full high.
*Adjust by scrolling the touch sensor.
*The slow and high sides can be adjusted individually.
Linkage compensation setting procedure
*Prior to utilizing the linkage compensation settings, it is
important to adjust the mixing rate settings.
*Linkage compensation overrides interference from the
aileron operation with the elevator or elevator operation
with the aileron at collective pitch control for low pitch and
high pitch.
*When making the following setting, Move the cursor to the
item you want to set and touch the RTN button to switch
to the data input mode. Touch the RTN button to end
adjustment and return to the cursor mode.
1. Compensating aileron input [AIL]
Set the throttle to the lowest position. Move
the aileron stick to the left and right and
adjust the aileron compensation amount
so that interference in the elevator or pitch
direction is minimal.
*Adjust by scrolling the touch sensor.
*The left and right sides can be adjusted individually.
*If the interference increases when the compensation amount
was increased, make adjustments with the compensation
direction [DIR.] as "-".
2. Compensating elevator input [ELE]
Adjust the elevator compensation amount
so that the aileron or pitch direction
interference when the elevator stick was
moved up and down is minimal.
3. Repeat steps 1 and 2 above, perform aileron
and elevator compensation similarly at full
throttle.
Speed compensation setting procedure
1. Move the cursor to the "SPEED" item and
touch the RTN button to switch to the data
input mode.
2. Set the throttle stick to the neutral point
position. Quickly move the elevator stick and
adjust the speed compensation amount
[SPEED] for minimum interference in the pitch
direction.
*Adjust by scrolling the touch sensor.
Touch the RTN button to end adjustment and
return to the cursor mode.
