I know there is a thread on this plane but it is more or less dead..... I have an evolution .52nx in mine and i need a Pitts muffler for her, I cannot for my LIFE find one online.[:@] Any clues as to what one will fit on it? I also need a new cowel, anyone know somewhere that has them in stock? My wife was talking to me and distracting me and I cut the hole for the engine head on the wrong dang side!!!!![:@][&:] Thanks
