Its earlier in the thread but if the swash plate moves up and down to change collective pitch, its CCPM, whether you have one servo moving a pitch arm and the elevator and aileron links like a Raptor, or whether you have 3 servos and doing it electronically.

The Nexus, Concepts, Kalt Barons and some others used either a hollow main shaft with a rod up the center or two rods and a collar on the outside of the shaft to change collective pitch, and the swashplate remained stationary except for cyclic input, thats a non-ccpm heli.

This can go on for pages and nobody will agree but I can promise you the term CCPM was more of a marketing thing than anything else, the people that really understand helicopter control systems think the way I described above, and if you hear the term CCPM these days they are refering to 3 servo (though there's actually a number of variations of it)
