Dave, did you check the gain adjustment screw?

I'd bet Gyro. I have the telebee and I have the same issue but only when coming out of FFF into a hover the tail wags back and forth like a happy dog. I've tried all adjustments and to no avail. When you find it please let me no, it drives me nuts[&:] I haven't noticed it when doing piros though.

BTW I'm in construction[:@] Interior mostly but some exterior structural steel framing. I do steel stud framing, drywall hanging, drywall finishing, ( which is my forte'), acoustic ceilings, ( or ceiling grid systems and pads), and Stucco.
Pays the Bills

God Bless Y'all!
