| Aaron, a properly setup eccpm machine will not need any mixes for interaction and shouldnt be tried, there is no simple sane way to mix out the interactions of eccpm, what most people are accusing as interactions is the effect of spinning rotor with a helicopter underneath it.....all helicopters have a lot mass front to back, but very little from side to side.....when you go to feed it cyclics, most helis will move around because of this. the mixing for this is not for interaction.
Tmoore, fwiw, I have a background in the field of mathematics that governs how all this control system mumbo jumbo works, there is a valid point to the e and m stuff when you get into how it works beyond the software side (thats the easy part to figure) you are thinking of an inline system which differs from a sliding swashplate (ccpm, e or m whichever way you paint it)....I would say "good enough" for most pilots, they all work, but there are some large differences in the current e- and m- that a pilot who has played around with them both can prove without getting technical.
from what I know, I would choose mccpm before eccpm if that was a choice, the simple reason is that controls that move with mutual exclusivity are statistically provable as more precise (its all relative BS, but quantifiable). when you get three servos attempting to move a swashplate, you better know your math to make it a solid interaction free performer, so far most of the stuff on the market is a compromise because you cant design everything to be right all the time.
the reality between eccpm and mccpm is very slight in the stuff thats out there, usually shows as cyclic drifts at extreme collective ends.
not all the mccpm systems are so hot either, they can be improved, the best system (mathematically) is an inline sliding collective, where the swashplate never moves, these are rare because of parts count and costs.
most people are going to say good enough, eccpm hovers great, etc, etc, in most cases it is good enough, I wouldnt make the mixing system a big point in determining what to buy if you havent tried them all out, they will all fly! |
