I'll check out the Fox muffler you sugggested....our field likes "quiet" engines and we have new neighbors that feel the same way.

Thanks for the prop suggestion, a 14 prop will be on my list, I think this brute is broken in but I'll know more when I bench test it.

(I used to live in Alexandria myself....been to Arcola/NVRCC but that was many years ago....
I like that Flyin King too).
