Thanks MikeB. I set them up to function but currently have a reverted back to a plain old "Y" connection as I am still getting a feel for this plane. Maybe in a month I'll be ready for some experimentation.

I have the flaps to elevator mixing (the sadly discontinued 6DA is amazing for a non-computer radio) and also aileron differential. Thought I was losing my mind trying to set up the flaps until I noticed that the differential pot was full right. The drawing in the manual is different than the installation in the radio. The manual shows a 100% > 0% clockwise range instead of the 50% > 0% < 50% that actually exists. Good thing they wrote the scale in Lillipution-sub-micro-reduced-molecular font around the pot. so I could eventually read it. (As I was banging my head on the radio because I could only get one aileron to respond). These are difficult concepts for an old free-fight/control line upbringing like I had. My RC mentors, and lots of life experiences in non RC fields, have taught me that the functions must be understood and the technique mastered before you let a computer or machine take it over for you.

I bought the Big Stik as a test-bed, but things like that keep me cautious and sticking to baby steps. Happily, a tail dragger (this being my first) isn't as big a bug-a-boo as some would have you believe. (Now I've jinxed myself for sure).

Thanks guys.
