Second, Can you measure the length of your pipe on the Rossi engine and give me some dimensions. Let me know the starting and ending points and if you are measuring the outside radius, inside or on the centerline.
Jim,
I missed this. What measurement is it that you need? I'm not quite clear.
Just so you know, the header pipe being used is a Mac's long with an extension between the exhaust flange and he header flange (~1/2") to put it at the right draft below the fuse. The pipe will be a Mac's long stroke 10 cc quiet pipe. The header hasn't been cut yet to tune for the smaller, probably 11" x 7-1/2", props that will be used. A good average mount point for the pipe is about half way down the wing chord. Usually just along where the fuse side is on the top side of the wing. The header angles up and in slightly due to the nose ring side and down thrust but it's not a big issue.
