CCPM Swashplate Mixing
The CCPM Swashplate Mixing Function (Cyclic
Collective Pitch Mixing) of the mx-12 is designed to be
used in model helicopters that utilize 2-servo (180°), 3-
servo (120°) and 3-servo (90°) type swashplate control
system.
The desired swashplate mixing type must first be selec-
ted at the Swash Type Selection in System Mode.
If the Swashplate Type option has not been selected,
proceed to Throttle Cut section.

CCPM Servo Variations
2 Servo/180° CCPM
3 Servo/120° CCPM
(Graupner style, most popular)
3 Servo/90° CCPM
1.)
One servo (Standard Mechanical Miying)
The most common form of Swashplate Mixing.
This type uses each of the three servo to move the
swashplate individually for pitch, Aileron and Eleva-
tor changes. If one servo (NORM) is selected in the
System Mode (Factory Default), the Swashplate
Type Function will not appear on the LCD screen in
this section.
2.)
Two servo (180-degrees)
Two servos are used to move the swashplate, and
are spaced at 180 degrees apart. This is not a very
common control system configuration.
3.)
Three servo (120-degrees)
Three servos are used to move the swashplate , and
are spaced at 120 degrees apart. This is the most
common form of CCPM, and is found in Graupner
and other brands of Helicopters.
4.)
Three servo (90-degrees)
Three servos are used to move the swashplate, and
are spaced at 90 degrees apart. This is also not a
very common control system configuration.
