    Subject: Comparison test between Pietenpol airfoil and Riblett
    airfoil Very interesting, PF. Please keep us updated. I must admit, I expected to see some advantage to the Riblett, but there doesn't appear to be much if any. Perhaps further testing will reveal something. Otherwise it looks like, once again, that old Pietenpol fellow really knew what he was doing when he designed this airplane. I agree with Mike Cuy - looks like this would be an excellent topic for a forum at Brodhead.

    Ted, Rather than typing everything with Caps Lock on, why not just type everything in lower case, and not worry about capitalization of letters? IT'S JUST HARDER TO READ WHEN EVERYTHING IS IN CAPITAL LETTERS, AND IT FEELS AS THOUGH THE READER IS BEING SHOUTED AT. see what i mean? Just a thought. Bill C.

    Subject: Re: Comparison test between Pietenpol airfoil and Riblett
    airfoil PF, I am very appreciative of what you guys have done with this report. Real data is always better than opinion when trying to assess things like performance. My project has been stalled for several years thanks to a number of factors, not the least of which being trying to turn an old, worn-out farm into a working, profitable one (and holding down a part time teaching job at the same time to pay the bills while we get the farm on its feet), but I will be moving on to making ribs and wings in the next couple of years, and I've been contemplating which way to go. As far as performance goes, I'm a bit surprised to see such minor differences. I wonder how much the VG's on your wing contribute to performance? It would be interesting to learn whether or not that's a significant factor in the performance of your wing. The other difference I'm thinking about is that, when using a center section fuel tank, which I'm planning to do, I think the Riblett has more potential capacity. When using a Corvair, that may be a consideration, since it has a higher fuel consumption rate than an A-65. The other issue that your work does not address (and I'm not sure it can, but maybe you'll look at this later) is the potential difference in CG envelope on comparable planes.

    airfoil What about the vortex generators? That's a major difference in my opinion. I 'd like to see the same number and type of vortex generators put on the 612 t o see if there's a difference. Also, were the gross weights at take off the same? Maybe I missed that in t he text. Great information! Thanks for doing this.

    Subject: Re: Comparison test between Pietenpol airfoil and Riblett
    airfoil Dan, that was part of my question. PF's wing (original Pietenpol) was the one with V.G.'s. I would think that would substantively change performance & I would like to see 2 additional 'experiments 9although PF says he's leaving his VG's on, so one experiment would have to be with another, comparable plane). First, a comparison of Don's plane to a plane with a 'clean' Pietenpol airfoil, and secondly, as you suggest, a comparison of PF's plane with Don's after putting VG's on Don's wing. It appeared from what PF wrote that they made a good effort to make sure that takeoff weights were as close to the same as practical.

    Subject: chicken and ribs
    I don't know about you guys but I was astounded with how incredibly well my Piet would climb when the engine was new for the first couple of years. Incredible performer really on only a 65 horse engine and the Piet airfoil. I'm really glad to see this news from PF develop so future builders can have a better set of knowledge when choosing which wing they want to use. I know one thing, keep the empty weight in the 630-660 range and you'll have a good performer with a fresh 65 Continental. Mike C.

    Mike, I couldn't agree more. The key to a good performing Piet is the old saying "simplicate and add lightness". The Piet is very affected by excess weight. Not only does extra weight hurt the climb, it also makes it more sluggish in the air at cruise speeds. It also raises the landing speed, which creates more stress on the gear because it is going faster with more weight. The airplane was designed to be simple and light. If you are still building, try really hard to resist the urge to add this and that. Try to keep it the simple and basic machine it was meant to be. Okay.... I'll quit now. :-) Don Emch NX899DE Read this topic online here: http://forums.matronics.com/viewtopic.php?p=393101#393101

    Studies have shown that we do a much more efficient job reading lower case letters THAN ALL CAPS for extended reading.

We actually can read text that is quite scrambled as long as all the letters are there. ARMY ORDERS are still written in all caps. The root reason was to simplificate for the teletype. A much simpler system was required if you only had 26 letters (one case) plus 10 numbers. With both cases it was 52 letters plus 10 characters. No need to do it that way but the Army Standard is still to write major Orders in ALL CAPS. Hard to read. I would write your operations manual with both and do your placards in ALL CAPS.

    The quote that I've seen is "Simplicate and add lightness", and is attributed to William Stout, designer of the Ford Trimotor. >From Wikipedia (so it must be true :) ): Stout is remembered for his Farberistic engineering credo, "Simplicate and add more lightness." This would later become best known as the adopted maxim of Colin Chapman of Lotus Cars. It actually originated with Stout's designer Gordon Hooton. In the spirit of the quote, "simplicate" makes more sense than "simplificate", if for no reason other than it has one syllable less. Bill C.

    Hey guys; i got a ride from Mr. Beck at the last CC ( one of the most gracious guys you'll ever meet). i did inquire about his vortex generators and he did say how they allowed a slightly steeper deck angle on climb out. Mr. Beck, maybe you could swap that "Johnson" type airspeed indicator between the two birds to get 100 % accuracy when comparing numbers. Here us a link of a vortex generator manufacturer who gives a good explanation of benefits, along with testimonials. they're only about a hundred bucks. i put them on my hang glider and noticed a small difference. the cubs that ive flown with them realized an approximate 4 mph difference in stall speed. you could also put some just near your tips, or more near your tips to give better aileron control during a stall. another benefit of that Riblett wing for those contemplating, is that you can build just one large center section fuel tank vs two tanks. Taller wing and all. To sum up, difficult to compare both those planes unless you could verify your climbing, stalling... with confirmed identical airspeed indicators. Thanks again Mr Beck !

    I have a copy of "The Speed Seekers" by Thomas G. Foxworth . On Page 83 there is a bit on William B. Stout, designer of the Ford Tri-Motor transports. I quote exactly: "His lifelong doctrine was 'simplicate and add lightness.'" So we can assume that he coined the expression, and it certainly holds true even today.

    Irregardless Bill, I will Endeavor to persevere in pushing my spelling. I will pursue it ;until it has reached leveliddity with the other word in use. One of my favorite terms in aviation is "Cheap, fast, or efficient! pick two!" That points to the "envelope" and the only way to truly expand the envelope is to put money in it.
