i'll agree, the programmability of my 6ex is really nice, but it takes a whole book to do anything to it. and in the end, both radios do the same thing, in that most benefits from "more than 4 channel" radios are things that you really don't need to fully accomplish and enjoy r/c flying. I think the greatest benefit to my 6ex is being able to have separate aileron channels and flaperons. this is one thing that cannot be had with a non computer 4-channel. most other programabilities, are issues that actually cheat the flyer out of actually learning all the points to flying r/c
