Mike,I am not a structural engineer but I am an EAA Tech Counselor. Since this listhas been very quiet lately I will speak up with my own opinion. If you are goingto use a low horsepower engine like the model A or 65 Cont., I think thesmaller cables would be acceptable. Now if you are going to use a Corvair orCont. C-85 or O-200, I would be wanting the larger cables so I could sleep atnight knowing they will handle the potential heavier air loads. With the biggerengines we can carry larger loads adding to the wing loading. My question to the guys flying the Corvairs, Do you have the small cables on yoursand have you had any trouble with them? I have a C-85 Cont. and have 1/8 inch cables all around.My three cents.--------Scott LiefeldFlying N11MS since March 1972Steel TubeC-85-12Wire WheelsBrodhead in 1996Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Scott's Plane

My brother sent me this picture of Scott Liefeld plane parked at a fly-in overthe weekend. Notice how many people are are around Scott's plane versus to theones in the background. People know whats good. If you attend the West Coast Pietenpol Gathering at Frazier Lake this Saturdayyou too can see this unique bird.--------ChrisSacramento, CAWestCoastPiet.comRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/phot ... ______Date: Mon, 2 Jun 2014 16:27:20 -0700 (PDT)

I had never noticed that there is a difference between the plans and common practice.Hmmm... I've always looked at my 1/8" brace cables and gotten a warm fuzzyfeeling from them keeping everything square and taut out there. They twangwith a nice low 'thummm' that sounds strong to me. I checked the catalog strengthand 1/8" provides twice the breaking strength (2000 lbs) as 3/32" (1000).If you figure each of the four wires is about 10' long and the differencein weight is about .012 lb/ft, you're looking at a total difference of abouta half-pound between using the two different diameters. Maybe a bit more if youfigure the thimbles and nicopress sleeves for the two sizes.It's your call. I'd be curious to hear from any others who are flying Piets withthe smaller diameter wires. And like Scott, I would say if you're flying ahigher-powered ship, go with the 1/8". Drag increases as the square of velocity,so if an A65 Piet cruises at 65 and a Corvair Piet cruises at 75, the CorvairPiet will experience 33% higher drag force, theoretically. If the 3/32"wire had a safety factor of 2 on the A65 Piet, with higher cruise drag on thewings the safety factor would decrease to about 1.5 if the A65 was replaced witha Corvair. Or something like that.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Scott's Plane

Gary; that's only because you haven't put your airplane into a do-or-die dive straightfor a Hun ammo train racing for the border, with only you and your airplanebetween the enemy howitzers and the rounds that they so desperately needto stop the Allied advance!Will you hear the loud complaining of those over-stressed cables as the airspeedclimbs over 95 to 100, and then even unbelievably touches 105 as the locomotivecomes into your sights- and your altimeter unwinding so fast that the needlesare a blur?And will you be able to safely pull it out after sending your bomb straight forthe locomotive's boiler? I'll bet you'll be wishing you had that extra 1/32"of diameter that you left on the cable spool at the hangar... ;o)--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Tue, 3 Jun 2014 07:51:02 -0500Subject: Re: Pietenpol-List: Scott's Plane

Steve,Gap seals are not needed with the Frise type ailerons. Take a look at a cub andyou will notice that when the trailing edge of the aileron is up, the leadingedge of the aileron is actually below the bottom surface of the wing. It worksquite well.--------Scott LiefeldFlying N11MS since March 1972Steel TubeC-85-12Wire WheelsBrodhead in 1996Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Heat Muff Material
