I was wondering if somebody can tell me how our radios work? Not looking for a super technical discussion but a general overview and the differences(if any) between manufactures. I have been thinking(and yes it is a dangerous thing) of this since there has been some chatter about the following:
1.latency talk
2. servo grouping
3. the new R617FS receiver
4. module vs non-module

Basically I see it as a 4 step process:

1. We move the sticks, flip a switch, etc
2. The radio processes our inputs and generates move commands
3. the move commands are put onto a carrier wave and transmitted.
4. the receiver get the signal decodes it and sends it to the servos.

And it leads me to the following questions:

1. Is the above process correct?
2. When we move something on the radio does it calculate updates for all channels or only the ones that have changed? I would expect to see it only calculate updates for channels that have changed to speed up processing but I could be wrong.
3. How much data (in terms of channels) can be transmitted in one update to the receiver? I would think if data for all channels can be contained in one update servo grouping would be pointless.
4. What actually does a module do in terms of processing? Does it just put the commands onto the carrier wave and transmit or does it do more and if so what?
5. Will a person see better perfomance from a R617FS over a R607FS if the servo grouping of the transmitter is not optimized for CCPM?

Thanks for any info you can provide.
