    Good looking plane, Randy. I hope we can meet at MKL and fly up to Brodhead together with Gene. Enjoy your test flights. There is absolutley no greater feeling in the world than making the first flight in a plane you built yourself. That grin you have in the last picture is nothing compared to the one you will have after your first flight Jack Phillips NX899JP _____ From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of RBush96589@aol.com Sent: Wednesday, January 02, 2008 10:51 PM Subject: Pietenpol-List: taxi test Hello group, Got the wings on NX294RB and did some taxi tests,every thing seems fine.Just waiting on the FAA inspection.Here are a few photos.

    Subject: Aileron Hinge
    From: "Phillips, Jack" <Jack.Phillips@cardinalhealth.com>
    Scott the simplest way is to order the hinge pin a couple of inches long. Put a 90 degree bend in it about an inch from the end and then form a loop on that stub. Then you can run a screw through the loop, into the aileron spar to hold the hinge pin in place. That is essentially what is done on the elevator trim tab on my RV-10 kit (although on the RV-10, the bent hinge pin is just safety wired to the elevator spar This is one of the advantages of using multiple short sections of hinge (about the only advantage, I would say). On my Pietenpol, I peened the outer most hinge loop down on the hinges at the extreme inboard and outboard positions so the hinge pins could not work out. The rest of the hinge pins were then constrained by the inboard and outboard hinges. Good luck, Jack Phillips NX899JP _____ From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Scott Schreiber Sent: Wednesday, January 02, 2008 11:53 PM Subject: Re: Pietenpol-List: Aileron Hinge I bought one of each barn door hinge I could find. 3 inch and then 4 as well and there were allot of problems.

    From: hvandervoo@aol.com
    I used the 6 feet piano hinge and did not secure the hinge pin. First it takes a lot of force to move the pin out. Which probably indicates a not so perfect alignment but that is what happens when you start bolting it to the wing. The force needed to move the aileron around the hinge line is al most nil. Second it takes a lot of time to work itself out (if it=C2-does) and would be=C2-very visible during pre-flight Plenty of time to land if it happens in flight It has not moved in the last two years for even a fraction of an inch.

    Scott: My brother is a machinist and he laughed when I asked him to drill a tiny hole for the microscopic cotter key-not enough bi-focals in the world to make him see what he is doing clearly. I asked for advise from the list on obtaining a longer (longer than the 6" hinge) hinge wire so I can bend it to the shape shown on a Cessna hinge in the AS&S catalog. The end is a loop that will be secured under a screw. I don't want to shorten the hinge to reveal enough wire for what I want to do. Someone suggested piano wire. It comes in .090 d. which I believe is what the hinge wire is. My only worry is that since it more than likely comes coiled up, it may be hard to push threw the hinge. I Goggled, "piano hinge" and found some manufacturers who my be able to supply straight wires longer than the 6' (AS&S sells bare wires that are only 6") hinge. I haven't called any of them yet. If you talk to them, let us know what they have. Leon S.

    Subject: aileron horn geometery
    Guys I have another perplexing problem, at least for me, on the ailerons. When I laid out my aileron horns according to the '34 Hoopman drawn plans, they don't seem to exactly match up to the side view of the horn and the aileron together, as shown on the lower left side of the plans. The issue is the side view of the aileron and horn shows the upper and lower cable attach points being in a straight line through the hinge point. When I laid out the horn and aileron in autocad with the top cable hole of the horn on the hinge centerline, it appears that the bottom cable hole is 1/2 inches forward of the centerline. Also the two arms of the aileron horn are not equal in length, again measured from the hinge. The lower arm is 1-1/2" longer. My question.... is this right? Do the two cable attach points, on the aileron horn have to be on the same center line as the hinge? Do the aileron arms need to be of equal length. I can certainly redraw the horn to make things line up, but is it necessary? I'm pretty sure my aileron horn layout is accurate, since when I print it to the same scale as the drawing, the two match up pretty close. Rick Schreiber in frigid Valparaiso, Indiana

    Subject: Aileron hinge
    I just use a 1/16" drill bit to drill the hinge and use safety wire. You don't need to drill through the hinge pin, just keep the pin a little short. That is a fairly common way of securing the pins.

    Subject: Re: aileron horn geometery
    Thanks for the reply Walt. I didn't even think about the different arm lengths being intentional to control adverse yaw. I was looking at my Tri Pacer this morning and the upper and lower aileron horns are also of unequal length, now I know why. On the Piet I was concerned about uneven cable tension, but it appears that is normal. As an aside I did alter the geometry on my elevator horns/walking beam, to make it more of a parallelogram rather than a trapezoid. This was probably similar to what Ken Perkins has done. It did take care of the problem of the cables going slack, but I still have some uneven cable tension.

But it has drawbacks,,of uneven cable tension throughout control movement, to a point. Sorry for the long winded thing. walt evans NX140DL "No one ever learned anything by talking" Ben Franklin ----- Original Message ----- From: Richard Schreiber Sent: Thursday, January 03, 2008 10:56 AM Subject: Pietenpol-List: aileron horn geometery Guys I have another perplexing problem, at least for me, on the ailerons. When I laid out my aileron horns according to the '34 Hoopman drawn plans, they don't seem to exactly match up to the side view of the horn and the aileron together, as shown on the lower left side of the plans. The issue is the side view of the aileron and horn shows the upper and lower cable attach points being in a straight line through the hinge point. When I laid out the horn and aileron in autocad with the top cable hole of the horn on the hinge centerline, it appears that the bottom cable hole is 1/2 inches forward of the centerline. Also the two arms of the aileron horn are not equal in length, again measured from the hinge. The lower arm is 1-1/2" longer. My question.... is this right? Do the two cable attach points, on the aileron horn have to be on the same center line as the hinge? Do the aileron arms need to be of equal length. I can certainly redraw the horn to make things line up, but is it necessary? I'm pretty sure my aileron horn layout is accurate, since when I print it to the same scale as the drawing, the two match up pretty close.

    Subject: aileron control horns
    Rick noted- >It did take care of the problem of the cables going slack, >but I still have some uneven cable tension. Here"s a little excerpt from Chet Peek's book, "The Pietenpol Story": "May 20, 1929. As Bernard Pietenpol opened the throttle of his new Model A powered monoplane, he felt a welcome surge of power." "After a few circui ts of the field, he glided in to a smooth landing. As he taxied up to the waiting Don Finke, he must have thought, 'At last I've got the plane I want , a two place that flies good and has plenty of power.'" That airframe, wing, control horns, and basic design came from Mr. Pietenpo l's mind and hands over 80 years ago. I fly that airframe, wing, control h orns, and basic design every weekend. I notice no ill effects from a littl e uneven cable tension and I don't think you will, either. However, if you want to work on eliminating it, carry on. I've done studies of the contro l horn geometry and travel arcs in AutoCAD myself, but then I just turn off the computer and go fly.Oscar ZunigaSan Antonio, TXmailto: taildrags@hotma il.comwebsite at http://www.flysquirrel.net
