I even know a few places you may like to go in the evening!! I brew and grind my own so it took me a while to come up with that blend. Now all other coffee tastes bland. There is a step in setting up the DX radio where you have to put a channel in inactive mode? Without boning up on the programing I can't recall what it is. It's something for the two aileron servos. I only program that radio once a year or two. These days out at the field when someone is having a program problem and I see JR or DX I just walk back to my chair. All I would do is mess it up more. I do tell them who at the field to ask for help though.
My Futaba 9-C is something I just got used to. I think Futaba used Gorillas to test the programing just to make sure I would be able to do it myself.
Ch 8 is the default for using two elevators and 1-6 or 7 is used for the two aileron servos. You do have to activate them though but even I can figure that out. Heck, I can even mix ch 5 for elevators. The Gorillas weren't very bright so they were sure I could do it all by myself.
I'm not too bad with the JR 9303 but I don't let the instruction book get too far away from me when I'm setting up a plane. It too has some silly step I tend to forget about.
