That's about where the CG on mine ended up, glad to hear that it lands well at that setting. Are you using a SuperSonic muffler from RCS? If so, did you have to cut the cowl to clear the left bottom edge of the muffler? I'll have to cut a 3/4" x 5" slot in mine or the muffler will most likely melt part of the cowl as it is right up against it. I'm a little disappointed that it doesn't fit completely inside, but then again I get a little picky with cosmetics. Good to hear that it flys well, that's the most important part.
