"You never mentioned the muffler either. Did you get a "Pitts" style in-cowl muffler. If not, you'll have to cut a hole in the cowl for the muffler to stick out anyway."

I used the muffler that came with the engine. It DOES stick out of the cowling. I had to sand some of the side of the fuselage because the muffler was hitting it.

Let me just say that you guys are a load of information. I have never been in contact with such nice people. Once I get this built, I'll definitly join the club near my house. I live in HOUSTON if any of you are from around here. The nearest club from me is in George Bush Park. It's right next to the gun range, which I also go to.
