When you look at the fundamental cost of 2.4GHz technology it is clear that the early adopters were gouged and that in time 2.4GHz will be the low cost radio control technology, and it will be different from the current channel systems, being more like a Zigbee network.

I can imagine that servos will have an address and the transmitter will contact them using that address. It will no longer be emulating the PWM channel concept.

I do think that eventually 72 will be phased out, but the difference between the network bands and 72 is that networks are licensed to broadcast on those bands, as we are not and the control of however many thousands of hobbyists flying their models is much harder than the networks. If I flip on my transmitter once the "Switch" is made, what are the ramifications? How easy would it be for the FCC to find me? I think it will be much more difficult to do this switch, but I think it will come too. In the next 2-4 years, the prices will plummet. I can't justify spending $100 for a FASST receiver, that's ridiculous. I will wait until the bugs are mostly worked out of the Turnigy radio out on HC and then slowly make the switch.

I really do like the idea of 2 way communication with 2.4, I can see in the near future the plane being able to tell you the rpms, temp, battery life even speed and altitude in real time, I am partially waiting for that.

Why not RC Cars have a way for the transmitter to pick up RPM's,temp,ect.. Spectrum has it for the cars already !
