As a bit of additional trivia, I have since discovered that the #139 Federal Yellow is also referred to as Federal HIGHWAY Yellow, and is the color that is used to paint those stripes that you see on every interstate highway in the country. One more piece of trivia, but it's Piet related: there is a new Oshkosh/Brodhead update on William Wynne's website, http://www.flycorvair.com , including pictures of "The Last Original", Mr. Pietenpol's personal Corvair-powered Piet.

Just nail them, preferably with the nails horizontal through the uprights and into the spar (I nailed mine with the nails vertical through the capstrips, but AC-43.13 does not recommend this). The ribs need to be able to "float" a little when you trammel the wing. Likewise, do not bolt your leading edge in place or attach the plywood to the leading edge until the wing has been trammeled and the drag/anti-drag wires tightened correctly. Both the leading strip and the plywood will add quite a bit of stiffness and may prevent you from adjusting the wing properly during the tramelling process. Once it is trammeled, gluing and bolting them in place will lock the wing geometry in place. Also, after trammeling the wing you can glue the aileron spars in place (you might need to slip them in place before bolting on the wing tip and trammeling the wing). Jack Phillips Finally got NX899JP home from the Great Trek to Brodhead and Oshkosh yesterday evening. Got weathered in at Rome GA for a few days. 2,147 miles and 37 hours of flying (average speed 58 mph). Only major problem was a cracked exhaust manifold which required welding in Jackson, Tennessee. -----Original Message----- --> Pietenpol-List message posted by: "Egan, John" I would like to learn more about wing assembly.

Importantly, it is also necessary to have all the capstrip in the same plane. You don't want one rib a little high on the spar and the next one a little low as this will present an uneven surface for the fabric and the leading edge plywood and will be unsightly. Those at Brodhead should have noticed the 4-6 foot long sanding boards that were being used to "level" the Sky Scout wing capstrips in the Pietenpol hangar on the front row, west end.

Have them color match, get a quote. If you add one part "Bulldog" to your paint mixture, you'll get a slightly more flexible paint than standard automotive metal paint, this goes on very nicely over the Stits silver coat. Air Spruce gets their chuck of the cost of paint at a high premium over what you can buy paint directly from outlet like most all pro paint suppliers. DuPont, PPG and ICI are the prime automotive paint suppliers in this market, pro paint supply distributors are more competitive than AirSpruce when it comes to pricing, and they're lots of tech help too.

If you noticed, the rib spacing varied on the Sky Scout wings to keep the wires from coming in contact with the ribs. Greg and I measured them and they were off as much as an inch.

Secure a four foot 2 x 8 or so board upright on your table at the root end normal to the long axis of the spars. Secure two uprights to this board making a slot to capture one of the spars' root end. Use a little bit of trig to determine the position of that spar's tip at the wingtip end so that the spar is normal to the root board. Secure two more pieces of wood to the table, making a slot for the spar at the tip end. By pushing both spars against the root board and dropping the spar into the slot at the tip will ensure a glue up of a true wing. The wing should be glued true. The trammelling is to ensure the wires don't pull it OUT of true. Chris Braumeister und Inspektor der Flitzer und Flitzermotoren ----- Original Message ----- From: "Egan, John" Subject: RE: Pietenpol-List: Wing Assembly I made up a square long enough to span the width between the spars and normal to one spar to ensure my spar ends are lined up well. When I ran the temp drag wires, I found that the wire touches three rib members, so I am laminating another piece of 1/4 x 1/2" member in those locations, and will trim the interfering member. I saw this done at Oshkosh last week, and it looked like a clean solution. Thanks again, this is really good discussion.

I did notice that Denny (the guy working on the one piece Sky Scout wing) had used temporary diagonal wires to square the wing, then loosened the wires (I assume) after the ribs were glued in place. I've just been stuck for while at this point, and I recently found the Matronics site, and moved back to Wisconsin where I can now visit Brodhead and make good progress on my Piet. It sounds like as long as the wing is square, and how I want it, I can glue the ribs.

It is now complete and the airworthiness inspection is done. Unfortunately, my flying partner and good friend in the project has lost his eyesight and this has pretty much taken a lot of the enjoyment out of the plane. Therefore, I am putting the plane up for sale. It is a long fuselage, 3 piece wing, Sitka spruce ship with a C-85. If interested, contact me and I can send pictures or provide additional information.

Actually, he shows three different trim setups but one uses a push-pull Bowden cable and single bellcrank on the trim tab and the other two are variations that use separate bellcranks for push and for pull. Seems fairly straightforward to me, except the bit about how and where to transition the cable out of the fuselage into the control surface and out the fabric to the bellcrank. No idea "how much is enough" though. Cut and try?

No landings shown cause landings are a non-event.... what counts in the video biz is the stability of the shot in motion. I have a Kenyon Labs gyro attached to a camera mount that I helped design. The gyro has 2 weights that spin at 22K rpm. Much like a heading indicator. It;s smazing the power the gyros have in stabilizing. It fits in the palm of your hand yet is very difficlut to rotate when it is up to speed. I'm working on a new camera mount which will utilize 2 gyros at 90=B0 to each other to help stabilize the yaw axis. I just started this business 2 months ago and already have ad agencies calling and police dept. calling me wanting demo flights. got 10 payng gigs lined up over the next 14 weeks. I have found a GPS/inertial semi-autonomous controller that will reduce pilot workload up to 75%. This is a good thing for small 30lb helicopters... they require serious attention and coordination. Will be getting one in a few months. If all goes well this may become my primary source of income in the next year..... the downside? as I said.. it's eating up the GN-1 funds and time... rest assured though that come December I WILL start covering my wings! come hell or high water damnit. ok..... enough of my rambling.... sorry.
