RE: CCPM
Alfred......
There's mCCPM and eCCPM
Any setup that moves the swash plate up and down on the main shaft (which is pretty much all modern designs) use some for of cyclic/collective pitch mixing.
However as standard practice when you hear the term CCPM most people are refering to eCCPM (there is much debate about this)
So today we have mechanical mixing and ccpm (in common terms).
Mechanical mix birds like the Raptor have a collective pitch servo, an aileron servo and an elevator servo. Collective pitch inputs only cause the pitch servo to move.
CCPM have 3 servos usually attached 120 degrees apart around the swash plate. A collective pitch input causes all three servos to move in unison to push the swash up or down. An aileron input causes the opposing servos to move opposite tiliting the swashplate left or right on the axis thats maintained by a radius pin and radius block. An elevator input causes the two opposing servos to move down while the elevator servo moves up or the aileron servos to both push up and the elevator servo pulls down.
