I've been thinking a bit about creating an open source radio control TX/RX system. I think that as a community, we can do better than what Spektrum/JR/Futaba/etc. have been putting out, and certainly do it for cheaper (adding two channels seems to double the price of a radio these days, which doesn't make sense). I've seen the Open Source Spektrum Receiver, and it's really excellent, but I think integrating something like that into a full system, potentially using the Arduino platform, could be very powerful. Thoughts?
