Thanks Gene ________________________________ Message 2 _____________________________________ Time: 08:16:30 AM PST US From: Steve Ruse Subject: Re: Pietenpol-List: A 65 exhaust Gene, Here is the heat muff I was looking at. I have no idea what the quality is like, or how effective this one is. It looks nice, but the only mode of heat transfer is from the header to air, there don't appear to be and fins or anything to help heat transfer. http://www.robbinswings.com/Carb_Heat_Muff.htm Also, claims are made that ceramic coatings on headers help insulate the header to keep heat in the exhaust and keep exhaust velocities up. I'm skeptical that a significant insulating effect could be had by this thin coating, but it is something to think about. Tests after the heat muff is installed on a header with a ceramic coating verifying that the RPM drop is adequate would make me comfortable with it. Let me know what you think.

They seem like they would have a much better heat transfer rate with the inlet at one end and exit at the other. I bet this guy could make one with only an exit at one end, and the other end could be drilled with 1/2" holes to provide the inlet. Since the air will spend more time traveling along the header, I'm sure you would get more heat than with the other "split tube" design. Maybe the builder could provide some insight on expected RPM drops using these with lower HP engines. http://www.robbinswings.com/Custom.htm Steve Ruse Norman, OK Quoting Gene & Tammy : > > Steve, I just noticed a set of Aeronca system heat muffs on e-bay.

Talked to my A & P friend yesterday and he says that he may have an extra set of straight pipes. He's out of town for a few days but will look when he gets back. If not, I will have a set made up as soon as I can (in the next week or two). Thanks again Gene ________________________________ Message 5 _____________________________________ Time: 01:51:55 PM PST US From: airlion@bellsouth.net Subject: Pietenpol-List: CG question OK guys,another question from the dumb ass. Very soon I plan to mate the wings to the fuselage so I can cut the struts to fit and give it a weight check. Is it possible to check the CG,and how close will it be after taking it apart again to cover and paint? Gardiner Mason--- by the way, I have closed up the rear door, and I think it is much stronger than before I cut it. The front door I'm beefing up too when in the closed position.

Today I flew for about an hour and a half, and really just took in the experiance. It was nice and warm, farmers out cutting off the beans, some cutting hay for the last time of the year, and the leaves starting to change color before they die and fall off at the end of another flying season. The smells of fall harvest can eaisly be detected from 800 ft in an open cockpit. You can also taste the dust coming off the bean fields as they run the combines undernieth you gathering the years crop. It's funny how fast the fields go from muddy dark brown with tiny green leaves poking out of the ground in streight rows, to dry light brown dusty and dead looking fields. I got to see most of this years cycle from the back seat of the Pietenpol. The only sad thing of it all is that in a month or so it's all over for the winter, and cabin fever sets in. On the other hand....It will force me to get back to building my airplane, so I can experiance the thrill of flying MY creation some time in the near future. To all you with flying Piets take advantage of every warm, nice flying day, they are in short supply for the year. To all those building, keep at it it! is all worth it in the end.

The last week or so has been some of the nicest flying weather in a long time. All this week is supposed to be nice too. Yesterday afternoon the whole family and I went to the airport to hang out. I went up for a nice afternoon flight. We went home and were there for an hour or so and my wife looked at me and said "you want to go back and fly more don't you?" Within a few minutes I was headed down the road and meeting my brother-in-law to drag him along with me. What an evening for flying! There is definitely something about open cockpit fall flying that is fantastic! Hey, no complaining about winter and cabin fever! I flew every month last winter except for February and that was only because I had the plane down for a little maintenance. Someday I'll wise up though. Seems like the guys that have been flying longer eventually lose the ambition for winter flying! Until then I'm looking for some homebuilt ski plans. Anybody have ideas?

One advantage of covering the fuselage plywood with fabric held off by fairings is that the fabric keeps oil, etc. off the wood. I don't know if this makes a difference overall, but some of the unprotected wood seems to have soaked up oil over the years and appears a little weakened by it even though it was heavily varnished. I don't know how general of a problem this is with uncovered wood fuselage.

Mine was about 2-3 lbs heavier. I covered my fuse with a 2 oz. layer of fiberglass cloth and used West System Epoxy, then applied Spar varnish over that. As I recall bare fuselage, fully finished was about 65 lbs. I would consider going with the wood thikness as on plans and where you are adding wood to the rear, use 1/16" plywood. Keep th weight donw in the rear.
