surface MENU
2) Press the ENTER key to display the <SET>CLNR menu. ACT/INH will
be highlighted and <INH> (Inhibited) will be selected by default.
IMPORTANT Prior to starting to use the Read Offset function below,
the elevator, aileron, and pitch servos MUST be centered (servo arms
set to 90º) and the Servo Reversing settings should be made, using the
CENT and REV functions.
3) Move both control sticks to the center (neutral) position. The center position is verified using the OUT display at the bottom of
the <SET>CLNR menu. When both control sticks are centered all values will read zero. With the control sticks centered, the
servo arms should be centered, as described above.
4) Press the Navigation Pad 6 to highlight READ OFFSET, then press the
ENTER key to display the <SET>READ OFFSET menu. SERVO
90º OK?>Y will be displayed.
5) Press the YES/+ key to verify the OFFSET value, then press the END
key to return to the <SET>CLNR menu.
When using either CP4A or CP4X Swashplate Types, EL2 values will
be displayed in addition to the EL, AI, and PI values.
If you press the YES/+ key and values are displayed other than zero, the control sticks are not centered. This is usually
caused by the throttle control stick not being centered. If this occurs, move the throttle control stick slightly toward center,
then press the YES/+ key again. Repeat as necessary until all OFFSET values read zero.
Activating the CCPM Servo Linear Function
1) After verifying that the READ OFFSET values are all zero, press the
Navigation Pad 5 to highlight ACT/INH, then press the YES/+ key to
change the value to <ACT> (Activated).
You MUST set the Channel Offsets prior to Activating the CCPM
Servo Linear function. If you don't and you attempt to change the
Rates, the CCPM Servo Linear function will always revert to INH (Inhibited).
IMPORTANT Do NOT change the CENT Adjustment Values after Activating the CCPM Servo Linear function. CENT
Adjustment Values should be made prior to Activating the CCPM Servo Linear function.
Changing Channel Rate Adjustment Values
The Rate settings are used to fine-tune the swashplate and make it as
close to level as possible throughout the entire pitch range.
1) Press the Navigation Pad 56 to highlight the channel you would like to
change the RATE Adjustment Value for, then press the YES/+ or NO/-
keys to change the RATE Adjustment Value.
2) Adjust the desired remaining RATE Adjustment Values using the same
techniques.
EL, AI, and PI setting range is 0% to 120%. The default setting is 100%. Increasing the RATE Adjustment Value increases servo
travel and decreasing the RATE Adjustment Value decreases servo travel. Do NOT adjust more than 20% in either direction.
IMPORTANT When the CCPM Linear function is Activated, cyclic servo travel is compressed as a result of changing the
output from rotary to Linear. If when you change the Rate Adjustment Values the control throws are still not enough, you can
increase the control throws as necessary by increasing the End Point Adjustments or the SWH Adjustment Values.
