From: "tools" I finally folded on this subject after reading the poly fiber manual about it. Addresses this exactly and in no uncertain terms says it's completely required. Even addresses not using uv protection on ultralights because of weight. It's kind of convincing.. And they recommend a compromise. It seems the best compromise would be skimping on the undersides of things, and/or on less critical things like the fuse. On my chief I'm gonna paint it one of three colors that has uv protection built in. Will save about five pounds and a thousand bucks. So, because they.say so... ? I don't know. I've just decided to agree. I would recommend reading the poly fiber book on it though.

I am planning on using the split axle version with 6" Cleveland wheels. I have read most if not all of the posts in this forum and obtained and digested the Doc Mosher collection of WWs articles on the topic. A question still remains. If main wheel location (0 to 3" behind wing LE) is dependent on wing location, and wing location (cabane tilt to get CG in proper range) is dependent on final W & B and final W & B requires a completed aircraft, how does one go about determining the correct geometry and dimensions for constructing the LG before the aircraft is completed? I would certainly like to avoid building the LG now using roughly estimated dimensions only to have to rebuild it when aircraft is finished. This really feels like a chicken or egg type situation. Thoughts! Thanx Grant Ziebell Savannah, TN Plodding ahead but making progress!

It must be the same on points 1) and 2), but if your maximum pilot weight is above any example listed, that is OK, I will show you the calculation to move the wing to the correct location for your conditions, and only from there do you get the main gear location. If you write back in with your three numbers, I will gladly use this as an example to guide others. The resulting numbers will not be a guess, they are a calculation, and it is a reasonable expectation that your finished plane will be within one half inch of the calculation. -ww.

From: "William Wynne" Food for thought: If I was in the middle of a 4 year build and considering a non-standard covering system, I would build a few 12" square test panels and leave them outside for many months, and punch test them. ----------------------- Given a choice between leaving the color off or the UV off, I leave the color off. Both our Piet and our Wagabond had the wings and the tails just done in Poly spray ( the 'silver' stitts UV barrier). Only the fuselage and vertical, and rudder were/are in Insignia blue Poly tone. (the color part of the system) Poly spray holds up, but it needs to be washed more often. Planes with matte finishes, color on the fuse and silver wings look 1930-ish to me. ------------------------ Grace's BC-12D was covered in stits 40 years/1,100 hours ago. It is still in good condition. It has lived indoors since it was recovered, but for the last 9 years we have had a full 40X50 hangar with several planes shelves tools etc. If it is not raining, I often push the Taylorcraft outside all day just to make more working space. It might get 1,000 hr./year in the sun just from this. Many hangars have translucent panels for sunlight that may block nothing. ----------------------------- I worked in the fabric shop of Willie Carter at Spruce creek 1993-97. We mostly did competition aerobatic planes, which would always be indoors, and would often be recovered every 5-6 years just as an inspection. Owners were rabid about weight, but I don't recall a single one of them asking to delete the UV coats. Willie's theory was it takes a certain amount of material to fill the weave, some of it might as well be UV coats. 100% of everything we did was Stits (polyfiber). -ww Read this topic online here: http://forums.matronics.com/viewtopic.php?p=429647#429647 ________________________________ Message 5 _____________________________________ Time: 07:14:58 PM PST US Subject: Pietenpol-List: Used Pietenpol plans From: Dan Plett The plans came with the Pietenol.
