theres three methods: 2 ccpms, 1 not

ccpm 1: 'sliding" swashplate, the mechanical ccpm (cyclic collective pitch mixing) examples being raptors, shuttles, robbe system 88.

ccpm 2: "eccpm","ems", "electronic mixing" "direct control" or whatever else you want to call it.....whatever fury, vigor cs, etc.

the in line swashplate not ccpm. a separate mechanism activates the collective. best examples are the concepts, fai helis.

whats most precise? in-line, what costs the most to make, in-line. whats quickest? ems. whats the most common? mechanical ccpm...but thats giving way to ems. what makes you fly better? none.
