you have to look at what radio manufactures are left in business today and you still have Futaba and Sanwa. I was always a Sanwa man and they are still around but there is not a lot of aircraft radios left compared to Futaba. Sanwa make some really great car radios and they are always doing something in that world but for the aircraft there is not much. There is only two sources for Sanwa in the USA right now. I switched to Futaba last year with the 8JA radio controland its a fantastic radio. it has more bells and whistles than I will ever need or use. I am not a fan of spectrum and it seems most of the guys at my local club have spectrum controls. One of the guys was telling me that Spectrum has some kind of new technology where the can tell you how much travel you can get at the servo level. I am a technology nerd but thats something I dont really need. Futaba and Sanwa have side business in the electronics world and they build controls as a side line!
