Thanks -- mechanically everything seems fine... new blades, upper and lower stock; new stock flybar. Shafts seems fine - at least prior to the change out there were no issues. Tracking looks good.

It seems like I'm going around in circles electrically. I know I saw an approach somewhere, but as I adjust gyro gain, the mix changes. Is there a "best practice" for setting one (probably gyro gain) first then approach proportional mix?

I've been on both extremes of the gyro -- full clockwise feels loose, a little input puts it into a spin. Full counterclockwise and she twitches and makes sudden unprovoked changes. This seems to contradict the explanation in the manual for the gyro gain adjustments.

As for Lipos, I've been using my 15Cs.
