Answer: Well, you could, but it wouldnt >be a Pietenpol anymore. And, the drag isnt that much less that youd see much if any difference >in cruise. The USA35b airfoil here is 11.5% thick and the Pietenpol airfoil is only 10.5% thick, so >the performance of the USA35b, if improved, could be from the fact that the wing would be thicker, >therefore, lighter than the Pietenpol, too. > >Can I decrease the negative pitching moment of the Pietenpol airfoil and end up with less trim drag >and have it fly faster. Yes. But you will have, as a consequence, less lift, too. And about the T'craft wing, Mike wrote: >a bit complicated, but you want as little trim drag as you can stand and yet still have enough lift >for your airplanes purpose or mission. This is most of the reason why C. G. Taylors Taylorcraft >flies 10 miles per hour faster than his Cub design: the Taylorcraft airfoil uses a lower drag airfoil, >the NACA 23012, but this airfoil also has very little negative pitching moment, only about 0.012. >If you have an airfoil which has less drag and significantly less negative pitching moment, you will >also have less trim drag as well, and, quite likely, significantly improved cruising speed.

Now I have to pack it all up and my ribs to move to the other side of the country to start a new job so no building for the next 6 months.

I guess they didn't test it before they posted or maybe they didn't upload them yet because they don't work, but I am assuming they will fix it. -Scott ________________________________ Message 5 _____________________________________ Time: 06:37:37 PM PST US From: Oscar Zuniga Subject: Pietenpol-List: great EAA video on Piets!!!!!!!

That trip by far was the most memorable I've made in an airplane. It literally brought me to tears when I realized I was on my first return leg home after Brodhead 99'. Now for some more tear shedding... I've put off writing about this for almost a month, but my Aircamper NX722 9R has been mortally damaged in a landing mishap. The poor thing has had i ts back broken. I sent it to live with my brother in south of Tucson for t he winter and on Dec 20, he called to say that he was OK, but the piet was badly damaged when he pancaked it onto the runway. A non-pilot airpark res ident had run a stop sign on the bisecting access road, and stopped in the middle of the runway when he saw my brother coming. Instead of simply roll ing on through he jammed it in reverse and backed up. This distraction cau sed my brother to let the plane slow, stall and drop to the runway. The lo ngerons and the crossbrace at the front gear/front lift strut attach point was crushed and buckled. The fittings were pushed together about 4-5 inche s. The wings sagged down as the gear splayed, but somehow the prop remain ed untouched except for a small dent on the leading edge when it hit a mesq uite tree when the poor piet left the runway. The lower cowling was damag ed and the gascolator deformed. Gas spilled, but thank heavens there was no fire. There were no injuries to the solo pilot. The crash was witness by an off duty officer and pilot, but since it occurred on private propert y no citation was issued. The driver has denied any responsibility and off ered nothing in reparations. Only thing left to do is file a lawsuit, but that really isn't in either of our natures. We are trying to decide if th e 10 year love affair with Aircamper 29R is over, or simply another chapter is to be written as we build up or repair the damaged fuselage. My broth er has said he will buy me out and rebuild. I still have the Stinson to f ly, but can hardly imagine being without a low and slow open cockpit airpla ne. Something in my head is whispering 0-200 powered? Maybe a new Rotec ? What about a 120% scale Piet with the 140HP LOM? Steve 'E' Spanish Fork, UT.
