Default RE: CCPM?

There is still mechanical mixing being done in many cases and in all cases where there is a elevator specific servo, aileron specific servo, and pitch specific servo
And again, my point is that there is NO mixing going on in my control system!! If you, the pilot, move the elevator stick, that is the ONLY control(servos, bellcranks, elevator yoke and swash tilts exactly fore and aft) that moves. If you move the aileron stick, that is the only control (servo, bellcranks, swash tilts EXACTLY sideways) that moves. When you move the collective stick, the elevator servo does not move, the elevator bellcranks do not rotate, the elevator yoke does not tilt.

With a collective stick movement, the collective arms move the yoke straight up and down, moving the swash plate straight up and down, NOT mixing in any elevator (adding or removing elevator movement) to accomplish it. The aileron servo moves up and down with collective movement due to its position IN the collective arms, but is not mixing IN any aileron (adding or removing aileron movement) due to the position of the points of rotation for ALL the controls.

Similar to what happened in the Helifreak thread, you have different people presenting a different argument on why it IS CCPM.

From the book I posted, a moving swashplate does NOT necessarily consititute CCPM.

In a single servo system (the term used by many RADIO manufacturers) with NO mixing, then it cannot be CCPM as the last letter "M" stands for Mixing.

A swashplate is NOT a "mixer".

Any mixing going on ABOVE the swash is irrelevent, we're discussing the controling OF the swashplate.

If you can refute, WITH documentation from a reliable source (wikipedia is NOT, LOL...), ANY of my arguments as presented, then I will concede and begin my advertising campaign that we now have a CCPM control system in the Intrepid Line of helicopters. Can you IMAGINE!!
