    Thanks Jim
    I have factory built wings. But rib one was my work and hence my comment on making little errors. I had the same binding issue as Carl mentioned in the rudder pedal torque tube and really don't enjoy having to make adjustments that just add time and effort uneccesarily. So I'm exposing my insecurities out there in the hope all you guys can help keep me from the extra work. I have aircraft maintenance experience but fabrication is new to me and although this is supposed to be a learning experience I really appreciate what everyone adds to the build process with the methods that proved successful for them so that I'm not learning the hard way. I really prefer things done without Jerry Rigging it. Flight controls without binding is good.

    Hey Eddie, I just went back to look at what I did and I never posted anything because I lost the pictures.

    I remember this being a two person job. Make your marks on your ribs and then with it fully supported in several places so it doesn't sag, put the flapperon in place. If you are like me, your #1 rib won't line up perfectly and you will have to bend a little "S" curve in the hinge on the flapperon. This is pretty typical and lots of people have had to do it. Once it's all in place, shoot the bearings with LPS 1 and you will be amazed at how much of a difference the LPS makes.

    Sorry I couldn't be more help but this should get you in the right direction.

    I have seen the S curve before. I dread the hole drilling part of this build. I started this project with discovering I have some things to learn about running a drill. I wish my drill had a built in level. the reinforcement plates that are on the ribs don't have a very big flange in which the rivets hold the flapperon brackets on. If I dont get these on straight and drill nearly absolutely perpendicular then the rivets will be awfully close to the edge. Thanks for your input.

    Take some small clamps, clamp your brackets to your rib, and back drill through your bracket then add clevos. This way the hole is exactly where you want it and you drill can't wander. Get a second person to stand at the leading edge and tell you which way to angle your drill before you start. Makes a big difference with a second set of eyes.

    got the right side mounted today. A bit of S turn in the #1 bracket needed but no binding!
