Just a little something to think about.
A few years back, I had a Thunderbird that had a hunting problem that was getting the best of me. I tried everything. Played with the CG, tweeked the elevator and lead outs.
It was suggested by one of the local hot shots, to add in a touch of down thrust.
When the big shots speak, I listen.
So I simply added washers under the front mounting lugs, then lo and behold, no more hunting.
Like I said, something to think about.
