Great explanation Tippy:
I have been doing some homework and have been reading to understand this new concept to me in my new heli interest.
I found in the latest issue of Model Airplane News (October issue) a great CCPM explanation oriented to the performance of the heli regarding of the separation degrees on the controls of the swash plate.
As you just said the raptor needs a normal servo configuration and a complex linkage is in order to obtain the correct inputs to move accordingly the swash plate.
In the Model Airplane Magazine the author of the review shows the physics effects of the swash plate movements and claims that should be better if we apply a 135o (3 servos) rule instead a 120o (3 servos) in the swash plate configuration.
Well, then CCPM is not that good and maybe a normal configuration (As the raptor) could be the best, paying off course the price of the linkage weight.
Also the author says that modern computer radios compensate the 120o fault by increasing and decreasing some servo-swash plate movements.
I really recommend the reading of that particular review and maybe we can focus now on the effectiveness of the normal or the CCPM systems for a better control of any Heli.
