One more thought:Check out which airfoil is flying when the ambient temperatures are in the high90's, and you want to take a friend that weights over 200 , up to cooler air.You just might need an 0200 or more to even get off the runway. Only my experiencesof many thousand hours since 1941, has taught me a few well learned lessons.By the way, did Mr Pietenpol ever install a Corvair engine with out the suppliedblower ?Pieti LowellRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: What to look for in a 3/4 built Pietenpol

I may go look at a partially built Pietenpol that sounds like it is on its gearand mostly covered. I think it is a short fuselage, 3 piece wing, and has anA65 that has 800 hours but hasn't run in a while. It's been a 10 year projectthat the builder has lost interest in. Unfortunately I couldn't get a lot of informationdue to spotty cell phone reception but I'm going to call back laterthis week to get more info. I may go look at it this weekend but if I do whatare some of the things I should look for? Are there some gotchas I should keepan eye open for? I need help coming up with a checklist and questions I shouldbe asking so any help is appreciated.Thanks.JamieRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I'd say to definately find out what glue was used and the procedure=2C mix ratios etc... Some are very particular on how they're done. Check out the joints as much as you can see them. Are the joints tightly made or are there large gaps? Check to see that it is square - bring your own measuring tools too. Check weld quality - by quality I guess all you'll be able to see if if the welds look pretty clean and even or are they really irregular and full of holes and slag. If you have the plans=2C take them with you and check out as many dimensions as you can. Someone else may pipe up on the engine but I guess first and foremost - does it turn over and does it have compression? If it's sat a long time the bearings may be pretty dry - might plan a rebuild into the cost just to be sure you're not getting screwed.If the price is right and it looks to be of average or better quality=2C you probably have a winner.My $0.02Tom B.> Subject: Pietenpol-List: What to look for in a 3/4 built Pietenpol

I am vaguely. The only aircraft I remember seeing that used them was the Swift.Continental made a gazillion of this type engine. It was a 6 cylinder versionof the C-85. Displacement is 282 cu. in.The C-145 and the O-300 were developed from the C-125 just a little more stroke.C75,C-85 and C-125 cylinders are the same part number. So I would think it wouldbe a pretty good engine design wise. Most of those C-125's on the Swift havebeen replaced with Lycoming O-360's not from a reliability standpoint butto get more speed and climb.--------Jerry Dotson59 Daniel Johnson RdBaker, FL 32531Started building NX510JD July, 2009Ribs and tailfeathers doneusing Lycoming O-235Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: What to look for in a 3/4 built Pietenpol

Also find out what type of wood was used in the construction. Not everyone hasused spruce to build an airplane with, or aircraft grade plywood. There areacceptable substitutes for spruce, but you can't use just any ol' wood that kindalooks like it might be ok. Look for any major deviations from the plans,and if there are any, ask why they were made. Look at the hardware that was used. Is it AN hardware? Is there a builder's logor any photo documentation of the build? Is there a log with the engine? Sloppy building procedures and processes are usually readily apparent but sometimesthe basic craftsmanship can very good but still not be airworthy just becausethe builder did not have any experience with aircraft building. Buildingan airplane isn't the same thing as building a nice bookcase for the familyroom...--------Billy McCaskillUrbana, ILtail section almost done, starting on ribs soonRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 7 Sep 2010 22:24:21 -0700 (PDT)

I think this has been covered before, but the only real difference is that the 612 and 613.5 cross sections are deeper than the FC, so you will need to fill in the empty space that will exist above the spar at each rib location. There has been some discussion about this, with specific regard to rib incidence - I believe that the consensus is to align the rib centerline 90 degrees to the spar and set the wing incidence (relative to the fuse) by adjusting the cabane lengths?Kip GardnerOn Sep 11, 2010, at 11:50 AM, Billy McCaskill wrote:> >> Hi Joe,>> The only thing that changes when using the Riblett airfoils over > the FC-10 is the shape of the rib itself.

I went and looked at it today and it is pretty far along and seems well built.Here are some photos. I'm not sure I will be able to buy the project and if anyoneelse is interested I'd be happy to pass along the builder's name and contactinfo via email. The project is located on the CT/RI border near Westerly RI.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/dscn ... ______Date: Sat, 11 Sep 2010 13:50:49 -0700 (PDT)

Hi Gardiner,Not that I know that much about pressure cowls, but I recall Kurt Shipmansaying how he improved his cooling by increasing the opening at the bottom.With that in mind, I can't see how louvers on the low pressure side would doanything but help...at least they wouldn't hurt.Gary Boothe Cool, Ca.
