Hey guys,
I had the 6XAS when I bought an US 40, sold my 6 channel and bought the 9C, and it is great. I have mine set up to do all the tricks that the US manual shows you. I'll try to post how I programed my radio after this weekend after it is all sorted out.
If it helps, I went through the programming while checking the result on my airplane as I went, by moving the control surfaces. It does take some time to sort out the p-mixes but the rest of the radio a blind guy could set up.
