You'll probably find that only one or two people know the answers to questions like:
All these questions and many more are answered in this Rather Good Guide® for Programming the Spektrum DX9 for Fixed Wing Aircraft.
One of the first transmitters we encountered when we started flying multi-rotor copters professionally back in 2012, was the Spektrum DX9. This computer-controlled transmitter contains a dazzling array of features, but the manual is only 43 page long and dives straight into concepts that we didn't understand using unfamiliar terms that we didn't understand either. Over the years, we found out more and more information, hunting and gathering it from the Internet on sites such as rcgroups.com (the thread is only 65,000 postings, after all).
Gradually it dawned on us that only a handful of RC pilots really understand how the DX9 transmitter works -- and more to the point how to make it work for them. The manual was just too hard to figure out so most people did not bother. They bought the DX9 for what it could do, but discovered that making it do what they needed was way too hard. Until now.
It's been a year in the making but we're finally ready to publish this in-depth guide to the Spektrum DX9 Transmitter. We're pretty sure that you've never seen a manual as good as this one. It's well written, explains concepts clearly, and shows you what to do and how to do it. It has numerous worked, real-world and tested, examples, and you can find things quickly and easily with a detailed index, table of contents, table of figures, and nearly 900 "hyperlinks" so you can jump back and forth around the Adobe PDF file on your computer, tablet, or even your Smartphone if you're out at the flying field.

The DX8G2 lacks some trim switches and a couple of analog controls. The full comparison chart is here. But this DX9 Guide covers all of the features of the DX8G2 -- just be mindful of the differences though.
