Neutral point setting procedure
*Becomes the compensation reference point.
*Adjusting the servo horn so that the neutral point position is
near the 50% position makes the mixing amount small.
1. Hold the servo horn at a right angle to the
linkage rod, and then touch the [Enter]
button and read the actual neutral point.
*The neutral point is displayed on the screen.
After reading this neutral point, use other
compensation functions to make further
adjustments.
To exit the setting, touch the [Swash] button.
Swash AFR setting procedure
Adjust so that the specified operation
amount is obtained by aileron, elevator, and
pitch operation.
1. Touch the button of the AFR rate to be
adjusted. Adjustment buttons appear on the
screen.
2. Use the adjustment buttons to adjust the AFR
rate.
Initial value: +50%
Adjustment range: -100%~+100%
+or- The direction of operation changes.
To exit setting, touch the [Swash] button.
Mixing rate setting procedure
HR-3 is described as an example. The mixing
applied in other swash modes is different, but
the setting procedure is the same.
1. Set the throttle stick to the set neutral point.
Adjust the length of the linkage rod so that
the swash plate is horizontal at this position.
*A little adjustment using sub trim should be
OK.
*Adjust so that pitch operation when the
pitch curve is straight is maximum.
2. Adjust the AIL->PIT amount so there is no
interference in the elevator or pitch direction
when the aileron stick is moved to the left
and right.
*Adjust the left and right sides separately.
3. Adjust the ELE->AIL and ELE->PIT amounts
so there is not interference in the aileron or
pitch direction when the elevator stick is
moved up and down.
*Adjust the up and down sides separately.
4. Adjust the PIT->AIL and PIT->ELE amounts
so that the swash plate is horizontal when the
throttle stick is set to maximum slow and full
high.
*Adjust the slow and high sides separately.
To exit setting, touch the [Swash Details]
button.
Linkage correction setting procedure
*Set the linkage compensation after setting
the mixing rate.
*This function compensates for elevator
interference by aileron operation or aileron
interference by elevator operation at Low
pitch and Hi pitch at collective pitch (HR3,
etc.) control.
1. Set the throttle stick to the maximum slow
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 at that time is minimal.
*The left and right sides can be adjusted
separately.
*If the interference increases when the
compensation amount is increased, make
the compensation direction "-".
2. Adjust the elevator compensation amount
so that the interference in the aileron or pitch
direction when the elevator stick was moved
up and down is minimal.
3 . P e r f o r m a i l e r o n a n d e l e v a t o r
compensation similarly for the throttle stick
full high side.
To exit setting, touch the [Swash Details]
button.
Speed compensation setting procedure
1. Set the throttle stick to the neutral point
position. Move the elevator stick quickly and
adjust the speed compensation amount so
that the interference in the pitch direction is
minimal.
To exit setting, touch the [Swash Details]
button.
Notes:
If the linkage is too long or short, correct
compensation will not be applied. Correct
this before continuing. The pitch angle
changes after any adjustment. Reset the
pitch angle when actually flying after
compensation processing.
