RE: Semi flexible elevator control rods ?
" I think your problem lies elsewhere. " Wrong ! My problem lies with Sullivan Gold-N-Rods ! I have experienced the expansion/contraction properties of these for years. I would never again install Gold-N-Rods in any aircraft that I built, it's just that they came previously installed in a plane that I purchased at auction. Yes, I flew this plane many times with the Gold-N-Rods, and the variation in trim settings throughout the days flying is terribly annoying.
I ripped them out, and I'm now looking for replacement suggestions. I have used the Sullivan # 585, and they are fine, but my local hobby shop is out. Steel is also good, but their weight may unbalance my already balanced airplane.
