I'll throw in my 2 cents..........I'd go for the Futaba 7C.........not that much more than the 6EX but a few more features and truely if you never need to upgrade.........this is a perfect radio......just my opinion but if I was to need another radio the 7C is what I would go for and I'm flying a 10C right now.........just because I have a twin and a giant scale scale warbird that I need the extra channels.
