I can send a picture of a non-flying rotary powered aircraft. Hope to fly before summer '02. I have question for Tracy- What size of muffler are you using now that you put the muffler under the airplane? I have access to a bunch of 4.495" and 4.5" dia .020 thick inconel tube for around $12 a foot. Could you run a perforated 3" dia exhaust pipe through a section of the inconel tube, pack it with SS wool and hang it under your plane? I've been vacilitating about my radiator/exhaust configuration, and have been toying with having an engine cowling like Alan Tolle's, except that the  bottom of the cowling would hang down about and inch or two lower than stock, with a cowl flap extending back about 2 feet, and the exhaust pipe exiting the lower left corner beneath the firewall and hooking into a muffler that  extends from the firewall back to ? The radiator would be underneath the engine.
Thanks

I was at Tracy's place last Monday and here is a picture of his Edelbrock
SS muffler.
