Well I don't have anything to add, but it does have a psychological affect. I am still torn between buying a fancier 4 stroke or going cheap with an X-Air. I find I was going between them and learning as I went, but now I have this bad feeling about 2 strokes, mainly as I now believe, based on the article, that although I can get the X-Air for $15,000, I am going to need to spend that again to replace the engine in a year or two, so I might as well just spend $40,000 (or less) on a 912 powered plane.
So psychologically it helps kill the two stroke.
