I'm getting a Stihl FS65AV, 20cc trimmer engine that I was going to use for an r/c boat engine ,but it is too small for that, so I thought I'd convert it to use on an r/c airplane.I did a search and found a thread where someone converted one, but he made his own prop hub, which I don't have the machine to do that.It doesn't come with a muffler either so I'd have to find one of those also. Are there any places that sell conversion parts for a Stihl engines. I looked on Wacker Engines site and Carr Precission, but no luck.Will any of the parts made by these sites fit a Stihl ?
