If your swashplate moves up and down for collective and tilts for cyclic, so the commands are being mixed somewhere below the swashplate (CCPM).
And this is where the confusion is. The commands are NOT mixed. THATS my whole point.
If you take each control individually, removing the other 2, disconnecting the servo, however you wish, each control will work independently.
Moving the collective up and down in NO way adds or subtracts ANYTHING to or from the aileron function. The servo doesn't move(rotate), it simply rides in a cradle.
Now don't mistake the up and down movement as a mix. The ORIGINAL Intrepid control had the aileron servo in a stationary position. If you are confusing this with the ROCKING servo mechanism used in the original X-cell, don't. The difference is that the pushrods from the rocking servo DID move fore and aft, causing a bellcrank(s) to rotate, mixing in a control movement. The collective system REQUIRED these pushrods to be in place, there were no OTHER pushrods, independent pushrods, to move the collective.
In MY helicopter, remove the aileron pushrods, you'll STILL have a collective control movement, ie a swashplate that moves UP and DOWN. Remove the collective pushrods, You STILL have aileron control!!! With that FACT, how are you then MIXING Collective and Aileron? They are 2 totally independent systems.
I could explain the elevator in similar terms, but you get the idea. Without any mixing of the controls, mechanically or electrically, then you cannot call this control system CCPM.
I hope tommorrow to scan a page from a book from Dave Day. Only 1 page, with one drawing, that may explain this better than I can.
