| I also want to use the TX with the G3 simulator.
G3 comes with a perfectly fine controller of it's own -- you don't need to pick a radio that is compatible with it, though they can all be made to work.

| My questions are: | 1. What are the key differences between the Futaba and the | DX-7?
Well, they work differently internally.
The DX7 has a lot more computer radio features than the Futaba -- more mixing, better display, etc.
The DX7 comes with digital servos. The FASST system comes with none.
The DX7 has more channels (7 vs 6) though you probably won't need all of them.
| 2. In a full sized radio, is the DX-7 worth the extra $ | compared to Futaba?
Depends on if you need the extra computer radio features. You might not for your first plane, but your second might.
| 3. With the proper servos, is there adequate range to the | DX-6 to safely sport fly a .40 sized airplane?
Spektrum says no. Though it's not just about range -- they're also worried that the big engine could block the signal even if the plane isn't too far away.
