Good news!!! That fixed it!
(At least for one battery...)
I just took my wagging-tail Nano and loosened the feathering shaft until I was able to get about 1mm of play between the blade grips if I pulled gently on them. Then I took it for a flight and there was NO, I repeat, NO tail wagging at all! Woo hoo!
I've still got 2 more batteries charged from last night so I'll run them through this heli to make sure that this was in fact the solution.
