What is the diffrence between these pcm and ppm
I am using a FP-R127DF Futaba dual conversion FM 7 channel receiver. With 4 s3151 servos, and a Futaba 401 gyro with one s9254 servo.
What is the diffrence between ppm and pcm, I think i know the diffrence between these and pccm. these do not use the electronic mixing functions on the head. correct.
Please help to explain which is which and why.
Along with what the Shuttle plus is.
