The JR 120° three servo CCPM relies on the radio’s special CCPM swashplate
mixing, rather than a conventional mechanical mixer that is utilized to achieve the
same results. The radio’s 120° 3-servo CCPM function automatically mixes the
three servos to provide the correct mixing inputs for aileron (roll), elevator (pitch)
and collective. The following is an example of how each control input affects the
servo’s movement:
1. COLLECTIVE
When a collective pitch input is given, all three servos (A, B, and C) move
together in the same direction, at equal amounts, to raise and lower the swashplate
while keeping the swashplate level. During this function, all three servos travel at the
same value (100%) so that the swashplate can remain level during the increase and
decrease in pitch. As mentioned, this mixing of the three servos is achieved through
the radio’s CCPM program.
2. ELEVATOR (PITCH)
When an elevator input is given, all three servos must move to tilt the swash-
plate fore and aft, but their directions vary. The two rear servos (B and C) move
together in the same direction, while the front servo (A) moves in the opposite
direction. For example, when an up elevator (back cyclic) command is given, the
two rear servos (B and C) will move downward, while the front servo (A) moves
upward so that the swashplate will tilt aft. During this function, the front servo (A)
travels at 100%, while the two rear servos (B and C) travel at 50% (

the travel
value) of the front servo. This difference in travel is necessary due to the fact that
the position of the front control ball is two times the distance of the two rear control
ball position as measured from the center of the swashplate. This mixing of the
three servos is also achieved through the radio’s CCPM program.
3. AILERON (ROLL)
When an aileron (roll) input is given, the two rear servos (B and C) travel in opposite
directions, while the front servo (A) remains motionless. For example, when a left aileron
(roll) command is given, the left rear servo (C) will move downward, while the right rear
servo (B) will move upward to tilt the swashplate to the left. As mentioned, the front servo
(A) will remain motionless. The travel value for each of the two rear servos is 100%.
