G. Cyclic Corrective Pitch Mixing (optional)
CCP mixing is performed after the helicopter correc-
tive pitch and cyclic pitch control systems are electri-
cally mixed. Since direct linkage from the servo to the
swash plate is possible by using CCP mixing, the model
can be made lighter by eliminating the intermediate
mechanism. Linkage rattle is also minimized.
30 CCPM switch
1 and 2 turn MIX ON-OFF
and switch the pitch direc-
tion when the CH2 (eleva-
tor) servo is operated as
the pitch servo.
Fig. 46
•When mounting the servos in the fuselage, mount
the CH1 servo (aileron servo) at the right side facing
the front and the CH6 servo (pitch servo) at the left
side facing the front.
•Set the CH2 (elevator) up and down directions with
the reversing switch. Next, set CH2 elevator to pitch
operation and set the switching and pitch direction
with CCPM SW1 and 2.
•Check if the high, low, aileron left and right, and
elevator up and down directions are correct by pitch
operation.
•Set aileron CH1, elevator CH2, pitch CH6, ATV, and
2nd ATV to maximum.
•Set the CCPM switch from OFF to 1 or 2 (ON).
When the CCPM switch is set to ON, the CH1, CH2,
and CH6 servos throw is automatically set to 50% of
the total travel.
• The CH1 and CH6 deflection width is set so that the
left and right throws of the two servos at each ATV
are the same.
• Adjust the aileron left and right throws using the
2nd A T V when CH1 and CH6 operate with mixing
ON. (CH1 and CH6 can be adjusted simultaneously.)
•Check the aileron direction when CH1 & CH6
operate. Use the reversing switches to correct the
aileron direction.
•The CH2 deflection can be adjusted with ATV or
2nd ATV.
When mixing is used, the swash plate is moved up and
down. Use a coaxial swash plate.
Since the servo throw is about one half of the total
travel, so that the servo horn throw must be adjusted
to make larger at the servo horn side.
