I had the 12x for years and it was great. The XG14 absolutely left it behind. I ran both side by side for a while and then sold the 12x and all the receivers when I was confident that the XG14 had surpassed the 12x in every area, as far as I was concerned. The 28X is something that I have my eye on at the moment, as I have a very large tomcat that is channel hungry. 14 channels will fly it, but 18 channels would give me more safety mixes to turn off flaps and slats and ailerons when swinging the wing, . Come on more channels, I can use them on this model. Some of the bombers I have had were very hungry for channels, but we always made do with what we had. Bomb bays, rotating turrets and the list goes on usually. It would be nice to have too many channels for once. just my opinion.
