Wow! Do you ever go into idle up? I think that's what popped mine loose. Seems that happened once before to me when I tried idle up. I don't do that too much; still a little scary for me and my flying space is just a little tighter than I'd like.

Flew all four batteries this morning in fairly calm conditions. The home construction project next to my little neighborhood park is progressing and so my airspace will be shrinking soon, not to mention the activity of all the construction workers in the meantime making me more hesitant to fly with them around.
