I have been using the MX-3X for about a year now, and originally looked at the Futaba radios since Futaba is what I started off with several years ago. That said, I LOVE the MX-3X and it has been trouble free for a year now. I am using it with two kits, a T4.1 and an RC18T2. The manual was confusing at first, especially when it comes to programming multiple models. The first time I tried to add a new model I accidentally programmed over the first one - the manual was a little vague, but I figured it out. I am very happy with it - and the range is fantastic. Both kits operate with zero glitches and the range is fantastic. My buddy has a Spektrum DX3E and I can easily out-distance him range-wise.
