I finally got around to making a tower tutorial. Its far from a complete guide but I did share everything I know and have tested. It includes the ever elusive method of actually putting Solo into autonomous mode which even the 3DR tower video skips. I also discuss region of interest, circle, and parameter changes. Its pretty long - 50 minutes so you might want to get some coffee before listening to me mumble for that long. Anyway, hope it helps someone out. Advanced tower users need not apply. Targeted at beginners.
