Update...I swapped the blades and checked the feathering shaft by turning one side. There was no wobble in either grip. I also dial indicated the tail shaft and it is true.
After swapping the blades the difference in static tracking was about 4mm. It tracks perfectly in flight and flies fine. I moved the gyro sensor from the front edge of the battery tray to the inside of the tray figuring the unsupported front of the tray would get more vibes. It stopped all tendency to turn and it holds fine now.
It still has the narrow tail minor twitch left/right that I would like to get rid of. It's not violent and I am going to try and get a video of it. Someone had mentioned leaning the low end needle, I'll give that a try next time. I can't actually hear the engine missing but they mentioned you might not be able to notice it. I just am leery of leaning it too much (Zenoah gas engine).
Thanks for the help!
