anybody tried flying the evo 10 gx with pitts muffler exhausting out the bottom...looks like my plane is not gonna let me use factory muffler without cutting on the plane and i don't want to that..just like to know what to do to get it run right..i noticed with my glow set up with it i have to open the high side about 1/2 round more...is this gonna work with the gas engine doing that...
