I don't know for a fact, but I have heard that at least some of the 9ch Futaba systems won't output more than 8 channels in PPM mode.
If the system uses PPM, then we are stuck with the update rate of a standard PPM system, somewhere around 20ms. The newer Futaba systems (12MZ and 14MZ) using G3 PCM have faster update rates, and I suspect any 2.4ghz module and receivers that Futaba comes out with will probably utilize the PCM data stream, or possibly have a firware update for something even better for their 2.4ghz module... | | | | | So... is the TX using PPM to communicate with the modules or not?
