Here they are: Wood Struts The original wood struts have Douglas Fir tops and bottoms sandwiching aircraft plywood. I bought them from a friend. I noticed signs of delamination between the fir and the plywood on all the struts at around the 250 hour mark. The worst delamination was on the left rear strut, which I used as a support point for loading passengers. Im pretty sure the guy who built the struts used T-88 but I dont remember. Anyway, a dear friend who shall, as always, remain nameless (Gary Boothe) made new struts for me. They are constructed from four hickory sticks laminated together. The glue lines on the original struts ran parallel to the wing, the new laminations are perpendicular. They seem quite stout though I have not flown them very long. Gary is a saint. Note: For what its worth, the holes on the old struts showed no sign of distress or elongation. Thats with 260 hours, several hundred takeoffs and landings, and a significant wing dragging episode on each side. Wing Cross Wires I used the cross wires at the right front cockpit to hold the wing in place. I can honestly say that I do not remember why. I also do not remember why on earth I lopped off the ears from the top motor mount where the diagonal cabanes would mount. Regardless, I added diagonal cabanes and got rid of the wires to improve ingress/egress from the front cockpit. I did not want to cut a bunch of fabric and remake motor mounts, so I carefully crafted an East Texas Redneck Modification (ETRM) to provide the front mount for the diagonals. I welded them to the vertical cabanes at the top. Ill improve that ETRM when we re-cover the plane. See attached photo. Clourcars Prop Ive taken so much abuse for the ugly-but-effective Warp Drive prop that I broke down and bought a wooden prop from Cloudcars. It is 68x34. They originally sent me a 68X27 which Jay calculated to be similar in pitch to my Warp at 7.5 degrees. It wasnt enough pitch. They very kindly provided another propeller. It appears to have a little more functional pitch than the Warp. The plane climbs a little slower, but still at better than 500 fpm, and flies about 10% faster. Since were not allowed to fly our Cloudcars in the rain I may switch to the Warp for traveling to and from Brodhead, and then use the pretty wooden prop while there. See attached photo. Landing Gear Springs I think Ive talked about this already. I re-did the gear with springs instead of bungees after one of the bungees failed and left me limping down the taxiway at an awkward angle. I used Hans Van der Voorts drawings. The Dreaded Corvair The Weseman 5th bearing has been installed for ~60 hours. So far so good. Last year at this time I noticed a sudden drop in power of about 150 rpm. It turned out to be a burned valve. Roy Szarafinski re-did the heads for me. The reworked heads actually give me an increase in static of 150 rpm. I originally had the heads done at a car shop several years ago. Its safe to say that Roy does significantly more sophisticated work than most car shops. Use as you see fit. -------- Kevin "Axel" Purtee NX899KP Austin/Georgetown, TX Read this topic online here: http://forums.matronics.com/viewtopic.php?p=364597#364597 Attachments: http://forums.matronics.com//files/painted_prop_211.jpg http://forums.matronics.com//files/all_3_mods_169.jpg ________________________________ Message 5 _____________________________________ Time: 02:05:40 PM PST US Subject: Pietenpol-List: Re: Modifications as the result of operational experience From: "K5YAC" What did you do with your 3-piece wing?

What kind of degree setting did you have on your warp drive. Also what was your static and cruise speed? I would like a cloudcars too but I need to get my plane flying first. I am about finished with the first wing. A good way to carry the prop would be tied onto your wing struts just out board the jury struts. You will never know it's there.
