Do any of you guys run JXF props I broke my xoar today and have to get a new prop. Also my J-tec muffler is going to be returned because I can't keep it tight. I went back to the stock muffler so I'm gonna order a new cowl, and the place I ordered my plane from has JXF props. So new prop and cowl together will save some shipping costs. But I want to know if the JXF ok.
