Dave Lavery in an earlier post stated

"You can build your own IR receiver board. You can also buy a different IR receiver board from any of a number of commercial sources (there are lots of them available with similar functionality). You can also use a completely different signaling technology. The IR boards provided in the Kit Of Parts are optional items - there is nothing that says you have to use them."

I've posted a Q&A question asking if he's correct " You can use a completely different signaling technology" If yes, I also asked if we can use 2.4 Ghz spread spectrum. I fly large scale radio controlled airplanes using this technolgy and it has none of the shortcoming of IR. We'll see what the Q&A folks have to say.
