    Subject: Happy Labor Day
    NX41CC did not fly this Labor Day. Still in the hangar, working on squawks from the condition inspection. You know how it is... you pull the cowlings and covers to work on one thing and you end up doing half a dozen others. I decided to change the engine thrustline to eliminate some of the left-turning tendency that the rudder trim tab does not correct, as well as a bit of nose-up tendency in cruise. Probably not possible to ever fly the airplane hands-off, but I'm going to work on it. Using washers on the engine mount bolts to put the engine at about 2 degrees downthrust and 2 degrees right thrust. It was set pretty much straight and level in both axes. I also had to remake one of the cooling eyebrow mounting tabs and the bracket that holds it to the engine. Fatigue cracks. We'll see how it flies... should be back in the air this weekend. There is the Critter's Lodge fly-in the 24th through 26th of this month, then Reklaw October 22-24, and then a fly-in at Kingsbury Aerodrome on November 13. Maybe able to make one or two of those.

    Joe, All of the airfoils currently being used will be suitable for the Piet, and the FC-10 - the original, is widely described in these pages. My Piet is being built using a three piece wing, with a center section baggage compartment. The airfoil I've chosen is the Riblett 613.5, which will give me 27% greater baggage compartment volume. If used for a wing tank, 27% greater fuel volume... In a Piet, with such little room for storage, baggage, cockpit covers, etc., increasing the size of a baggage compartment might be the most useful thing you can do to the craft. Since the plane is plans built, scratch built, and the philosophy of Mr. Pietenpol was to try different things, like the Corvair, for example, why not use another airfoil if it provides what you want in the aircraft? Just my .02 worth. -------- Tom Kreiner Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311663#311663

    Subject: Re: Happy Labor Day
    Oscar, Your note on adding washers to change the thrustline reminded me of this article I read recently. I'm not suggesting you did anything wrong by any means, your story simply triggered this in my memory. I just wanted to throw this out to the group as a reminder that it is very important to used tried and proven methods and materials when it comes to airframes, engines and other critical components. In this report, a Stearman lost his engine in flight. "Lost" as in, the engine fell off the airplane. This of course drastically changes the CG and makes the airplane uncontrollable. The Stearman crashed, killing the pilot. The accident investigation determined the cause of the crash was the use of low carbon steel washers on the engine mount bolts. In short, the low-carbon steel washers compressed more than a higher quality washer would've done during aerobatic maneuvers. This reduced tension on the bolts, which resulted in a shearing load being placed on the bolts rather than this load being passed from the mount to the airframe through friction on the washers (no bolt tension = no friction). This allowed the bolts to move slightly, causing fatigue and eventually failure. Prior to reading this, it would've been easy (for me at least) to assume that any steel washer would be adequate. Granted, our engine mounts aren't subject to anywhere near this type of stress...still, its worth the extra pennies in my opinion to use tried and proven parts wherever possible (unless you have the engineering knowledge necessary to deem a part acceptable). http://www.caa.co.za/resource%20center/accidents%20&%20incid/reports/2007/8321.pdf Steve Ruse Norman, OK Quoting Oscar Zuniga <taildrags@hotmail.com>: > > > NX41CC did not fly this Labor Day.

    Subject: Re: Split Axel gear width
    From: "Billy McCaskill" <billmz@cox.net>
    Jack, Steve was asking about the split steel gear, not the wood Jenny-style gear as you have on your plane. On my plans, the split gear is shown as 56" center to center between the wheels. However, the wheels shown on the plans are much more like ATV tires than motorcycle wheels. I think that Don Emch has split gear and motorcycle tires, maybe he will chime in and discuss how he built his landing gear. I see no reason not to make that dimension a bit wider to give better stability while taxiing and during take-off or landing roll-outs... Steve, maybe you should block up your fuselage with saw horses (or whatever it takes) to the proper stance and height to the top longeron that the plane will have while sitting on the ground, and then take the measurements for your landing gear so that you can build it to make it sit like it should. -------- Billy McCaskill Urbana, IL tail section almost done, starting on ribs soon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311711#311711

    Jeff, A while back you posted how you mounted your video camera to your Pietenpol, but I can't seem to find how you did it in the archives. Can you elaborate on what you use and how you mount it? I mounted my video camera to the rear cabane on N8031 a couple weeks ago but the vibration of the picture is pretty bad except when the throttle is almost closed. It's either due to the prop wash or the engine vibration, but I'm leaning toward prop wash.

    Dan, I bought an inexpensive mini-tripod. The legs are like angle iron in shape. When they are folded together, they can be strapped to a cabane. I use the velcro that the tripod came with plus plenty of electrician's tape. When I screw the camera to the tripod, it's upside-down, but your camera may fit rightside-up. Regardless, keep the camera from touching the tripod. I turn the thumb screw pretty tightly, plus I wrap tape around the perimeter of the camera twice, capturing the thumb screw on either side per turn of tape. There is a photo of a tripod/camera strapped to a tree at this link that is similar to this: http://www.amazon.com/Pedco-UltraPod-Lightweight-Camera-Tripod/dp/B000ANCPNM/ref=pd_sim_dbs_p_13 Note that you can find these tripods on the web for $10 or less.

    One more thought: Check out which airfoil is flying when the ambient temperatures are in the high 90'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 experiences of 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 supplied blower ? Pieti Lowell Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311750#311750

    Subject: What to look for in a 3/4 built Pietenpol
    From: "JGriff" <jgriffith19@comcast.net>
    I may go look at a partially built Pietenpol that sounds like it is on its gear and mostly covered. I think it is a short fuselage, 3 piece wing, and has an A65 that has 800 hours but hasn't run in a while. It's been a 10 year project that the builder has lost interest in. Unfortunately I couldn't get a lot of information due to spotty cell phone reception but I'm going to call back later this week to get more info. I may go look at it this weekend but if I do what are some of the things I should look for? Are there some gotchas I should keep an eye open for? I need help coming up with a checklist and questions I should be asking so any help is appreciated. Thanks.

    Subject: Review of Blakesburg Antique Aircraft Association flyin
    From: "ldmill" <lorin.miller@emerson.com>
    Went to Blakesburg, Iowa this year for the 4th year in a row - the big difference being that I actually got to fly myself there this time. I flew the GN-1 in on Saturday, September 4th. The weather was absolutely gorgeous! Severe clear with winds out of the west at about 6 mph - direct crosswind for the north/south grass strip. As I landed, I noticed there was a crowd of around 75 - 100 folks in the "peanut gallery" critiquing landings - which means that mine was definitely not as good as I'd have liked it to be - but hey - nothing got damaged... Taxiing to the assigned parking spot on the south east side of the field - it was like going down the red carpet in Hollywood - about 100 people lined the run and camera's were snapping. They pretty much did this to every non-spam-can plane that landed, but it sure made the old girl happy as she putt-putted past the line of Fairchilds, Curtiss Robins, Howard DGA's, Stearmans, Meyers, and a host of other golden oldies. Talk about a slice of heaven! I had probably 75-80 people stop by the plane and talk to me about it - it was amazing how many had actually either built a Piet, were building a Piet, thier grandpa/uncle/dad had build a Piet - or were thinking about building one. There was a ton of interest in this design. The old girl didn't win the dead grass award for the day - but she sure came away happy knowing that even though she's getting a little old - she's can still turn a young man's head... Cheers!

    Subject: What to look for in a 3/4 built Pietenpol
    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 m ade or are there large gaps? Check to see that it is square - bring your o wn 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 real ly irregular and full of holes and slag. If you have the plans=2C take them with you and check out as many dimension s as you can. Someone else may pipe up on the engine but I guess first and foremost - doe s it turn over and does it have compression? If it's sat a long time the b earings may be pretty dry - might plan a rebuild into the cost just to be s ure you're not getting screwed. If the price is right and it looks to be of average or better quality=2C yo u probably have a winner.

    From: "Jerry Dotson" <jdotson@erec.net>
    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 version of 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 would be a pretty good engine design wise. Most of those C-125's on the Swift have been replaced with Lycoming O-360's not from a reliability standpoint but to get more speed and climb. -------- Jerry Dotson 59 Daniel Johnson Rd Baker, FL 32531 Started building NX510JD July, 2009 Ribs and tailfeathers done using Lycoming O-235 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311767#311767

    Also find out what type of wood was used in the construction. Not everyone has used spruce to build an airplane with, or aircraft grade plywood. There are acceptable substitutes for spruce, but you can't use just any ol' wood that kinda looks 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 log or any photo documentation of the build? Is there a log with the engine? Sloppy building procedures and processes are usually readily apparent but sometimes the basic craftsmanship can very good but still not be airworthy just because the builder did not have any experience with aircraft building. Building an airplane isn't the same thing as building a nice bookcase for the family room... -------- Billy McCaskill Urbana, IL tail section almost done, starting on ribs soon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311773#311773

    I think what Pieti is saying is that if you build your plane with the original FC-10 airfoil that you will have a perfectly serviceable, good flying plane. But if you substitute the GA30-612 Riblett airfoil, you will have a much better flying airplane. Based on his experience (lots of it), and not just theory and opinion, I'm inclined to believe what he has to say. Here's a clip where he talks about the merits of the Riblett airfoils and his experience with them... http://www.youtube.com/watch?v=KHHnzw1V5FY I personally plan to build the 612 airfoil for mine, otherwise I am sticking rather tenaciously to the plans (aside from using one of those confounded Crank Snappin' Corvair motors). -------- Billy McCaskill Urbana, IL tail section almost done, starting on ribs soon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311778#311778
