CHAPTER 7: FUNCTIONS (FUNCTION MODE) • Helicopter 7.11 CCPM SWASHPLATE MIXING The CCPM Swashplate Mixing function (Cyclic Collective Pitch Mixing) of the XP662 system is designed to allow the XP662 to be used in model helicopters that utilize a 120° CCPM-type swashplate control system. CCPM is a type of pitch mixing where the three servos are connected directly to the swashplate of the helicopter and physically move both in unison and independently for all changes in pitch/ cyclic.

Press the SCROLL and INCREASE buttons simultaneously to enter the function mode. 3. Press the SCROLL button until “CCP” appears on the screen. 4. Press the INCREASE button once to activate the CCPM Swashplate Mix function. The screen will then move to the “CP2” screen, indicating that the CCPM function is now on. 7.12 5.
CHAPTER 7: FUNCTIONS (FUNCTION MODE) • Helicopter 7.13 HOW 120 CCPM WORKS As mentioned previously, 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° Three-Servo CCPM function automatically mixes the three servos to provide the correct mixing inputs for aileron (roll), elevator (pitch), and collective.
CHAPTER 7: FUNCTIONS (FUNCTION MODE) • Helicopter 7.13 HOW 120 CCPM WORKS (continued) 120 Three-Servo CCPM Swashplate Mixing The JR 120° CCPM or Cyclic/Collective Pitch Mixing system offers the user a control system that can accomplish the same control inputs as the One-Servo Standard system, but with increased precision and reduced complexity. As with the One-Servo system, the JR CCPM system utilizes three servos for the three main controls: aileron (roll), elevator (pitch) and collective.
