Jerry, Saw the comments about the muffler, did it have the long rectangular exit? I still have trouble about the VAM pipe, since they ran it without a tailpipe. (wihch was totally necessarry to the design) I know they couldn't fit it on Tracy's test stand, but I wondered if your pipe suffered the same fate? Thanks for the offer of the updates of the other list if needed. I really don't know what the problem is. Flyrotary gets bounces too sometimes. On your machining problem, you can order a custom sized reamer pretty easy from a machine shop supply. Takes about a week and they aren't even all that expensive.

Bill, the muffler did have the long tailpipe. I am disappointed by the test. Was it too loud or not? In testing Chuck Dunlop's plane outdoors, Paul stood about 20 feet away with the sound meter. Also, why not make a power run when we had the chance? I was looking for info that would with the design.........Jerry
