Pietenpol-List: Michael Cuy's Weight & Balance---please see attachment

William Wynne writes:"the reason why I am giving Mike C a hard time on W&B is actually on your behalf: I strongly suspect that Mike is not sharing his W&B because he is at times flying behind the aft limit. That is his choice, but when he then tells new guys like you to build your plane just like his, I think he is doing a disservice. If this is true, your loyalty is to the wrong guy. Mike, when you share the numbers, be aware that I am good enough to know if you are fudging it.Dear William-you have such grand visions of paranoia about why I have not shared my weight and balance. My world is not small enough to worry about what you think of me sharing or not sharing my weight and balancewith the list because the guy I am trying to help (as he stated just yesterday on the Pietenpol list) does in fact have paper copies of my original W&B paperwork in-hand, Mike Perez. I also copied the great notes for Mike Perezthat I had on hand for Mike Perez that Bill Rewey authored on how to do a good W&B on our little Pietnepol airplanes so Mike could have several different ways of doing his own calculations and choose the one that fit his mathematic style and likes best.And thankfully, with the outstanding W&B teachings and guidelines that my Uncle Tony Bingelis authored for us in this wonderful book series on homebuilt aircraft, I was able to conduct an accurate and complete W&B on my airplane and compare that with the dozens of Pietenpol builders whom I had met at Brodhead after measuring their wing set-back, knowing their personal body weights, and talking with them about how their plane flies full fuel, low fuel, long fuselage, short fuselage,extended motor mount, as-plans motor mount and soforth and examining their W&B paperwork to guide me as I built my Pietenpol and made my own decisions. Go ahead and double check my original pencil-drawn and .pdf scanned paperwork from 16 years ago that I prepared for myself, for the FAA MIDO Inspector, and for future owner/operators of my aircraft for when I am long gone but certainly not for you and your little paranoia's about why I haven't posted my numbers to the list. I have better things to do with my life than to fudge my data to see if you can catch any errors and I'm a bit stupid at times but I'm never stupid enough to build and fly my own airplane in an aft-CG condition. You're wasting your time worrying about what you "suspect" others are doing or not doing and what might motivate them and you are distracting from the good nature of this list with negativity and your critical nature that just divides.And William, besides making sure my plane was built to have a very safe and good operating CG range, I took great pains to ensure that my plane was built to the best of my ability, using all the educational reading materials at my disposal, and with the best aircraft-grade materials and aircraft engine overhaul practices of the day so that I could have confidence in flying safely for years to come and so that I would have confidence in giving rides to precious Mom's, Dad's, Grandparents, sons, daughters, school kids, Boy Scouts, Girl Scouts, Aunts, Uncles, little kids, big kids, old guys, young guys, young gals, old gals, Aunts, nieces, nephews, neighbor kids, 4-H kids, Young Eagle kids, my own brother, dearest friend Bill, the EAA photographers in the trenches at New Holstein, an F-18 West Coast Demonstration Team pilot who was building his own RV-6 (named James Shoenberger in case you "suspect that Mike Cuy isn't telling the truth...again.." ) , A Pearl Harbor survivor, an airport bum, people at the Brodhead fly-in and many other fly-in's around Ohio, Indiana, Pennsylvania, a high school friend and his children, his wife, his best friend...... and yes, even Michael Perez, his lovely wife Susan , and his two boys.Even last night I gave a ride to a precious High School senior from the area who means the world to me and her Mom, a Kindergarten school mate of mine from 50 years ago (that would be 1964) (we were 5 when me met) allowed her daughter to take flight with me and I had no reservations about giving her that ride and sharing this wonderful gift of flight that we ultimately build a 2-seat, open cockpit airplane for.Mike C.Ohio[cid:image001.jpg(at)01CFA8D3.1754C130]________________________________________________________________________________

Adding to the discussion (see attached):Today I moved out my Piet so John Howard could do W&B on his new Zenith 750.We had Pelouze scales supplied by our EAA Chapter.as opposed to when I didmy own W&B with a digital bathroom scale. Since all was there and ready togo, with help, I re-weighed my Piet.I was approximately 50 lbs off on the gross weight, but the numbers stillfell within the envelope [sigh of relief]. As a quick review:Long fuselageCorvairCabanes tilted 4"Gary BootheNX308MB

Steve (Emo)- I cautiously, respectfully disagree about the stock Piet wing beingexcessively strong. I have run some simple structural analysis numbers on thewing spars and am not convinced that there is extra strength in them. However,my calculations used several simplifying assumptions, such as (1) aircraftis designed for Normal category and not Utility; (2) spanwise loading on thewing is uniform, and (3) main spar carries a certain percentage of the totalmoment compared to the rear spar. I am hesitant to present my calculations, soI will only state that "I am not convinced", and "before you increase your grossweight beyond the Pietenpol family's stated 1080 lbs., do your homework". I could go back to the old aircraft design manuals and plug in the numbersfor the Piet spars, I suppose.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Michael Cuy's Weight & Balance---please see attachment

jesus christ this plane was designed in 1927.. old piety did all of the work andthinking.. dont worry about weight. just dont carry a fat assed passenger or be a fat ass yourself.. just dont fuck with any thing build it and fly it.leave the thinking to those dudes and dudettes that are good at it. i build exactlyto the plan and do NO thinking...i beleive that is the correct way.Read this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Oscar, from this statement am I to assume you havedivided the weight on one wing panel by the numberof feet of length?The span loading on a Hershey bar wing like ours isdefinitely not an even load along it's length. See theattached chart. The spanwise loading for this span/chord ratio wing panel is closest to the top one ( aspect ratio 6 ).Clif spanwise loading on the wing is uniform, > Oscar Zuniga________________________________________________________________________________

Well, not much of a report, but it went really well. I thought plenty of Pietsfor a good showing. Not as much flying as usual in terms of dawn and dusk patrols,but I finally did get my Piet there and got in a lot of flying.One gent came over, was looking at my plane and mentioned he BUILT one, registeredit, got it inspected, has taxied it, it's fueled and at the airport...but has NEVER even ridden in one! So we fixed that, gave a couple more rides to builders with no rides or experiences.LOTS of kids that work the event. One older gentleman who giggled likea school girl for the next two days. Really made the 10 hours of seat time gettingit there worth the effort. Probably 20 or more rides in total. Saddled up with the Minnesota crowd and the Canadian bird and flew into Oshkosh!THAT was quite an experience. So, pretty busy with my project at airventure, so will be quite scarce this week.Maybe I can get some pics and post them.

Mike (Cuy),Would you please repost your weight and balance data? I have encountered the "MatronicsTriangle" where postings often enter and are never seen or heard fromagain.I have seen the discussion of, but not the original post. If you could redo, thatwould be appreciated.--------Semper Fi,Terry HandAthens, GAUSMC, USMCR, ATPBVD DVD PDQ BBQRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Michael Cuy's Weight & Balance---please see attachment

Clif; I used a uniform loading from centerline to wing tip, so my analysis wasincorrect on several counts but I knew that going in. If I use the distributionin the graphic that you attached, it will be a bit different but not by toomuch. I analyzed the cantilevered section of wing from the lift strut attachpoint out to the wingtip, looking for the maximum moment to be resisted by theforward wing spar at the lift strut attach point. The inboard section of thewing is obviously going to be more competent to carry its load since it is supportedat both ends rather than being cantilevered. The rear spar is, similarly,going to be competent to carry its share of the load because it is lessheavily loaded than the main spar but it is equal in section.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Michael Cuy's Weight & Balance---please see attachment

One last, minor point: if the wing is rigged with washout, the load will be slightlydifferent from the graph as well. With washout, the root section is liftingeven more than the graph indicates (unless it has included some washout effect).All of which goes to help the Piet wing, but I remain cautious aboutincreasing gross weight without a reasoned structural analysis.We put men on the moon using slide rules and pencils; we don't need fancy computerprograms to figure out a wing spar structural analysis. I just haven't doneit myself or seen such an analysis done to my satisfaction. Your results mayvary, however.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Braniff1966,You don't really know how to speak in polite company, do you? You have sure beenasked enough times by forum members to do so. But you either can't or won't.After 10+ years in the Marine Corps I have the ability to speak as salty as youdo, probably even better. Cursing in the Marine Corps is an art form, but I choosenot to on this forum out of respect for others. It is obvious to me thatyou have none of that same respect for the wishes of others. That would involvecouth, of which you seem to have none.So how about aspiring to sound more intelligent than a 14 year old boy at a highschool football camp?Bill Church summarized it best.

I was doing my standard Sunday morning coffee drinking and decided to do a littleof what I call "Internet Dumpster Diving". I was searching for shop space inmy area, and came across this Craigslist Posting. I am attaching the link aswell as picture of the ad itself and the contact info. It looks like it mightbe a good source of nuts bolts, nutplates, and other small parts that you normallyhave to pay through the nose for. I plan on giving them a call in the morningand placing a small order to see if it is indeed a good source. Take itfor what it is worth (or at least the price you paid for it!)Have a great rest of the weekend. I am back to my coffee.http://atlanta.craigslist.org/atl/tls/4 ... ----Semper Fi,Terry HandAthens, GAUSMC, USMCR, ATPBVD DVD PDQ BBQRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/scre ... ___Subject: Pietenpol-List: Re: Michael Cuy's Weight & Balance---please see attachment
