This is some great advice TOPRUDDER......thanks for putting it into some kind of lamens terms for me. I don't quite understand how alot of this stuff works , but i think i understand what you are saying. The more channels you have going/or in operational use makes the latencey really bad , because it must read all the channels at once correct? So.......with every channel added , the latencey get's worse and worse. I guess it's how they we're designed a few months back , but now with the newer futaba stuff coming out , they seemd to have fixed the latencey problems with the higher channel radios , like the 12Z and 14Z is that right?
Just out of curiousity.....What would happen if you put two futaba's head to head for speed/latencey , with one being a futaba 12Z/with new futaba fasst moduel and the new futaba 12G , which one would be quicker.......or would they be the same speed?

Now there are three players in the 2.4ghz market. Competition will only make things better for us.
I agree with others that I would rather use a module for my radio that is made by the same company that made my radio. If there are any compatibility issues, who better to address them in the first place! I have 5 module based Futaba radios. Nuff said.
Unless the other module makers can decipher the 2048 G3 PCM, they have to use PPM. Adding more channels to the PPM pulse train will only make the latency worse. Each pulse in the PPM train adds a nominal 1.5ms to the PPM frame length, that is why you don't see many (any??) PPM systems with more than 8 channels. In fact, one radio that I am aware of allowed the transmitted channels to be programmed, which decreased the latency - great for pylon racers that only need 4 channels and want to bank-n-yank as quickly as possible! Going from 8 to 12 channels will roughly increase the latency by 50%. If this is the only way to get some 2.4ghz modules to work with my 12 channel radio, sorry, I won't buy it.
All the 2.4ghz options actually make our existing radios a little better. With all the guys rushing to get 2.4ghz systems, the 72mhz airwaves will be a little less cluttered. Sure, 72mhz will still be prone to shoot-downs, but with fewer radios on 72mhz the chances of that happening will decrease. We will also have to wait for the frequency pin less often now.
I will get one 2.4ghz module when it is available, but I won't be dumping all my 72mhz stuff right away, I have too many receivers on 72. I don't see any reason to make a mad rush to get rid of them.
