If you're talking about electronic CCPM then it would be rather difficult to get a drawing of the mixes happening inside your TX ... because for most ... the mixes IN the TX IS CCPM.

However ... it doesn't take much imagination to see how the swash is physically manipulated with an eCCPM set up.

EX ... 120° CCPM:


The collective function (assuming your heli raises and lowers the swash to accomplish this) requires ALL three channels to move together to lift /lower the swash evenly (no cyclic input)

The aileron cyclic function would require both pitch and aileron channels to work together to tilt the swash and does not require elevator input at all.

The elevator cyclic function would require ALL three channels: ail and pitch moving together and elevator moving opposite.


With CCPM, you have think of the channel designations (ail, elev, pitch) and the swash functions (ail, elev, pitch) as two different things because with eCCPM ... two to three of the channels are used to accomplish one function (ie ail, elev, pitch channels are needed to accomplish the pitch function ... or ... ail, elev, pitch channels are needed to accomplish the elevator function).

Mechanical CCPM (mCCPM) is a little easier because one channel is needed for each function (ie ail channel to produce ail function, etc). The "mixing" is done mechanically on the heli ... no need to "mixing" functions/channels in the TX.
