Unless Spektrum has reverse engineered the Futaba PCM data stream, then they would have to use PPM. 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.

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,
