| CCPMFWIW, I agree with jrice on his comments about ECCPM and having more servo power. This error has been repeated endlessly on the net, and promoted by the various manufacturers. The total amount of combined swashplate travel for the cyclic and collective functions doesn't change regardless of whether one uses electronic or mechanical mixing to do the job, so there is an equal amount of work to do with either type of mixing. Since both a mechanical mixer and the 120 degree ECCPM arrangements use three servos to do the job, there is an equal amount of available power with each of the two options. It should be intuitively obvious that both do the same work with the same amount of power, and that neither is superior in this respect. It is true that the ECCPM uses three servos to move the swashplate for collective movements, but does so using longer servo arms, and less than 100% of the total servo travel is dedicated to collective movements. Maybe there is a little bit of extra power available for collective, but if so, the power for cyclic movements will necessarily be reduced, since the total power available to the system is unchanged. Hope this helps. Steve. |
