So I have been pondering about a building a 1 or 3 piece wing. Without rantingabout the advantages and disadvantages that we all know about it seems to me likethe 1 piece is a no brainer IF you have the space. Tony Bingelis says thatsays that the 1 piece is 30-50 lbs lighter and saves you about 100 hours inbuilding time. Both of which are substantial numbers with weight savings beingfar more than important to me than time. My question is to those with flying Piets have you weighed your completed wing?I understand there are variables such as fuel tank or no fuel tank, stainlessor aluminum ect...Thanks, Fred KimRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Fred,Good luck with your decision. Mine is 3 piece by necessity. One very realbenefit for me was that, except for hanging the wings for W&B, I have beenable to lift, turn, hoist (hundreds...thousands...of times) all by myself.If you have built-in help, more power to you!Gary BootheNX308MB-----Original Message-----

Fred,I don't know about Tony Bingelis making ANY claims about the Pietenpol. Henever built one. I can say that I seriously doubt any claim of theone-piece wing being 30-50 lbs lighter than the 3-piece. I would believe10-15 lbs, but no more than that.Counter to the weight argument is the fact that the one piece wing is ratherfragile until completed and mounted on the airplane. While I built the3-piece wing myself (even though I had plenty of room to do a one-piece), Ihave helped Gene Rambo work on his one-piece wing and it is extremelydifficult to turn that wing over, even with two people. You really need athird person to support the wing in the middle as you flip it over. Thinkabout how many times you will need to turn that wing over as you build,cover and paint it. Then think about how you are going to transport it tothe airport once built. And if, like me, you are unfortunate enough to makea forced landing and need to move the airplane from the crash site by truck,a one-piece wing will again cause more problems.I did a lot of things on my Pietenpol that I would change if I were to buildanother, but I would keep the 3-piece wing.Jack PhillipsNX899JPSmith Mountain Lake, Virginia-----Original Message-----

Just noticed something kind of interesting in the 3 piece wing thread. That wasKevin's statement about building a three piece wing "next time". Dick N is on his third. I own one and am building. I knew a guy in San Diegowho built one, then bought one. Who else has built or owned more than one? Isit more common in the Piet genre to build or own multiples? Also, Piets seem to be built in multiples by groups, as well as multiples buildingone (as in EAA chapters). I'm sure the RV series has a bunch of this, bynature of the popularity.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: 1 piece vs. 3 piece wing weight?

Hey Fred,I really like the benefits of a one piece wing. Lighter and less to build. AlthoughI can't imagine it's much lighter than a few pounds. But having built/rebuilt/coveredseveral wings I honestly can't imagine dealing with such a largepanel. I'm glad I built the three piece. Someday when I finish the Piet mydad started it'll have the three piece, even if I have the space.By the way... are you Jr. or Sr.?

Fred,I am still in build mode but beyond the wing part. I built the fuse, wings andtail surfaces in a basement area that was maybe 18 feet wide at the widest and10 feet at the narrowest and 24 long at its longest, so rather a small space.Building the 3 piece was a necessary exercise in spacial logistics manipulation.Yet most of the time I was able to hang and move the panels by my self. Thenight I did my first trial fit I had help on one side the other I hung myselfa bit of an adventure but do able none the less. I am happy to have built the 3 piece rather than trying to move and manipulatethe length and bulk of the single wing. I hope this helps in your decision making process. Btw I have no scarf joints in my spars, just hardware connectors to the center section.

Guess I better reserve 59BP...So then, what is the correct answer to the original question? Regardless of engine,instrumentation, type of covering or paint blend, when was the first trueAir Camper flown? Doesn't really matter much to me... I'll continue to tell people that the airplaneI'm building is based on a 1929 design... is that correct, or we need to keepour horse beaters handy?--------Mark ChouinardWings, Center Section and Empannage and Fuse framed up - Working on Landing GearRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: 1 piece vs. 3 piece wing weight?

Hey Fred,I didn't make it to Beach City. The thunderstorms kept me away.I don't have any kind of trim system or tabs. My nose tank holds 14.5 gallons.When it is full I do have to hold some back stick, but it is so minimal I reallydon't even notice it. Even when flying cross-countries all day long it'sno big deal. You'll probably get several different ideas on this but I've neverseen it as anything I would need.Don EmchNX899DERead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I concur that the one piece wing cannot weigh much less, maybe 5 poundsmax??... maybe???My observations seem to reveal the chief reasons for building the one-pieceare:1. SOME weight savings2. SOME building simplicity, though offset in my opinion FAR OFFSET bythe PIA caused by it's size through the building process3. It's the purist form of Pietenpol wing4. and maybe the most important reason I've seen is. the all importantCOOLNESS FACTOR!! "Oh and. did you notice?.that's a one-piece wing upthere."If any of these, or a combination of the above are important enough to you,then go ahead and build a one-piece. I'm personally very glad I have thethree-piece for all the reasons stated by others.$.02Douwe________________________________________________________________________________Subject: Pietenpol-List: Re: 1 piece vs. 3 piece wing weight?
