CCPM stands for Collective, Cyclic Pitch Mixing. This can be done both mechanically and electronically.

Any helicopter that uses a floating swashplate is CCPM. The swashplate is what does the mixing. As it moves up and down the mainshaft, it adds or subtracts collective pitch from both blades. As it tilts fore/aft, or left/right or any combination there of it will add the appropriate cyclic pitch to the appropriate blade every cycle. So you can see that moving the swashplate up or down while tilting it in any direction will mix in both collective and cyclic pitches. Hence CCPM.

Heli's that use one servo per function to move mechanical mixing linkages below the swashplate to give the collective and cyclic commands to the floating swashplate are considered (mechanical) mCCPM systems. Those that use servos connected more directly to the swashplate and use electronic mixing circuits in the Transmitters software to command the floating swashplate are considered (electronic) eCCPM systems.

Heli's like the TSK Blackstar and Fivestar, Kalt Baron and Enforcer, Kyosho Concepts and Nexus and a few others use fixed swashplates for cyclic and used floating washout hubs or other similar mechanisms to deliver the collective pitch changes desired. They are considered non CCPM helis.

But the term CCPM has been so *******ized by the users of the language today that generally when one is referring to a heli as CCPM one is now understood as meaning a heli that is eCCPM (e.g Any JR CCPM heli, the Century Raven series, the Hirobo SPM (?) system etc.)

In truth, any heli with a swashplate that is designed to move up and down the mainmast is a CCPM helicopter.

I hope this clarifies it all for those who were not fully aware of the differences.
