RE: Great Planes Escapade .40 ARF
Perhaps yours has had the mods to prevent flutter? Or maybe you got one of the better ones. Mine fluttered with an Irvine 53 using an 11X7 prop. No damage but it did get my attention. And I had made mods to stop flutter.
I am not being critical of the Epade it is one of my favorite planes but it has its limitations.
In fact I am leaving just now to go fly it.
