confusion over CCPM,PCM,PPM,

[ChRiS]

wat do they stand for and wat r they??? very noob here

[fredrick]

CCPM is a type of heli control.

PCM is kind TX Freq Modulation.
PPM also a kind Feq modulation.

CCPM and PCM together with PPM has no link at all

While PCM n PPM has some link. PPM is an FM module with PCM is better in term of safety and 'price'

All the M

PPM - Pulse position modulation
PCM - Pusle code Modulation

CCPM - Cyclic Collective Pitch Mixing

PCM & PPM

[Brandon Chng]

all variable pitch heli have CCPM.

ccpms is so that you can add pitch and at the same time have the same elevator and aileron control.

mechanical CCPMs require the use of a dedicated pitch servo to move the pitch collectively(meaning both blades).

electronic CCPMs use three servos that are electronically controlled and 'mixed' to produce the elevator aileron and pitch functions. for collective movment, all three servos move.
