I've owned the 14MZ, 12FG, 10X, and now the 12X. If you're familiar with JR's programming, the 12X will be the easiest transition. Futaba menu structure is less intuitive for many common features, such as splitting dual rates and ATV into two separate menu groupings so you can not access either from the same menu... meaning if you were adjusting your d/r and wanted to increase travel through ATV (travel), you would have to go up two levels and down one. Also on JR radios, to increase D/R or travel, you press the stick in the direction you want to increase and then increment through the radio. With Futaba you have to use up/down, left/right arrows to change input. It's not terrible, but my preference for programming is with JR.
I like that the Futaba radios allow for complete control over switches and channel assignment. Of the radios I've owned, the 14MZ was the best, followed by the 12X. IMO, the user interface on the 12FG and 12Z was a bit cumbersome since Futaba adapted a touch screen UI for a non touch screen radio.
Dantley,
In Futaba Logic, you use the SETUP menu only to setup the airplane. Subtrims, reverse, atv, functions. The other menu with the afr, dual rates, and mixes is more geared to changes after the intial setup is done. You set the ATV for Max travel, and to match linked servos, then after they are matched you use AFR to set your high rate.
That is why ATV is in a different menu.
