Lateral movement of feathering shaft

[johncclayton]

Hi

I'm trying to get rid of some vibes in the X5 (as exposed by the spirit FBL vibe analysis). I have vibes ONLY when I've attached blades and spin up. The vibes are not visible with the naked eye, but the Spirit FBL vibe analysis does see them.

I've seen that I have about 0.5 - 1.0mm lateral movement of the feathering shaft - this seems like a bad thing me, but is it? Should I expect 0mm?

Here's a link to a vid showing the movement:

Thanks.

Is seems like your bolts are loose or your dampeners are worn.

I would take it apart and check your bearings, washers, shims and dampeners
