On my Kitfox 5 vixen, I have changed the rod end and nuts/bolts on both stabilizer tail brace because they where old and they do have some lash even after the bolts were checked.

All was ok on ground but after 20' of flight, there is some lash again with bolts checked.

Is it normal?
On the wings, rod ends do not have this lash.


I have seen since I bought this plane that during initial climb, the stabilizer leading edge is vibrating. Is it a "normal" happening?

I have send an email to John, but he is not at work until june 20th.
