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. Now this is purely speculation on my part since I don't know for sure. However, it will be interesting to see what Futaba comes out with for their 12 and 14MZ radios. I don't have one of those systems, but I have a lot of the older 7, 8 and 9 channel radios. I will be looking seriously at the Spektrum modules for my radios. The other question I have is regarding the binding of the recievers to the programmed model in the computer radios. The DX7 won't allow the wrong model to operate with a given program, I don't see how this can work in the other radios since there is no way to bind each programmed model. Thinking out loud, Bob R.

By all accounts, you are correct, Bob . taking PPM and translating it into the SS datastream with proprietary encoding, is much easier than decoding the proprietary Futaba, JR, hitec, etc etc etc signal and then recoding it for use with the Spektrum system.

After all, its a universal PPM signal, used by all manufacturers. Unfortunately, to get more channels, using PCM, you need digital encoding, so 8-9 channels is the limit for this process.

Still. . anyone out there use more than 5-6 channels most of the time?? I certainly don't.
