I bought a 6EXA. I don't need any of the mixing features yet. But I bought it so that I can have that option in the future. I'm a newbie in flying. I bought this Tx to use instead of my Skysport 4 that came with the Avistar RTF. The memory features are the most helpful with three planes so far.
I will be interested to hear what to expect from Futaba on this matter.
I haven't mailed the registration/warranty card in yet, but it should be out in tomorrow's mail.
