I used the hardware store strap hinges. Had a guy at work tack the loops closedfor me. (My welding was not that subtle at that point.) We used 2" packingtape for gap seals. All of this worked great for over 300 hours and three wing-tipdragging episodes (two right, one left). Despite this abuse, the straphinges proved very durable. We had the chance to thoroughly inspect the hinges during recovery ops. The aileronon the right side was intact but was stripped from the wing. The aileronon the left side was completely intact and still attached to the wing. Thehinges on the right side aileron were still firmly attached. Didn't check thewing side hinges on that side. The hinges on the left side were still firmlyattached on both sides. The left wing was thoroughly damaged but the aileronand the hinges were in great shape. I had a brief fantasy about ripping theaileron off with my hands. Fat chance. Very durable.More information to consider.--------Kevin "Axel" PurteeNX899KPAustin/San Marcos, TXRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Quick Update on the Plane & Me & Shelley

Larry,When I bought Felix the GN1 it had almost no offset and a steel trim tabbent almost 90 degrees, and it required quite a bit of right rudder. Ireplaced the trim tab with an alum tab bent about 40 degrees, I belive muchmore than 40 does no good. I still had to fly with right rudder. The nextmove was to offset the vert stab 7/8". Still had to hold right rudder. Iwound up making the right rudder cable shorter, to fool my feet intothinking they are holding neutral rudder. The combination of the 3adjustments did the trick, Felix flys great.All Piets and Gregas fly a little different, your GN1 may not need as manyadjustments, do any changes in small steps and have fun.Skip> [Original Message]

Reading Ben and Jerry's replies to my post really helps by interpolation ..Ben has an A65-8 like I do, has 1/2" displacement = not quite enoughJerry has an 0-235 with 3/4" displacement = perfect/no trim tabSo I figure my A65-8 and 9/16" displacement should = about rightWill be interesting to see how it pans out in flight..Yet another example as to how helpful/informative/valuable this forum is :-)Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Vert-Offset

Skip...Yes I had noticed my bigger trim tab ran out of effectiveness after about a 45deg bend, exactly as you write. I'll be quite happy w/a happy medium.In gusty turbulence with that rear view mirror I installed, I do feel concernedin large yaw's when I see that little vert-stab deflecting left and right. ThenI have to realize that this airframevdoes have 700hrs, so I suppose that littlevertical stab did prove itself. I'm probably over thinking it .... Like wholeglobal warming thing...Thank you for replying... Very helpful stuffRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 3 Oct 2012 09:12:26 -0700 (PDT)
