The hog bipe is pretty much built with a " Tab and Slot " construction method. Most of the mounting holes are already pre-drilled for you. The cabin struts and the wing to wing struts are pre- drilled as well as the ply plates they bolt into. It is my understanding that most people who built this plane said if you built it right it is almost fail safe as far as the wing incidence goes just need to line up perpendicular to the center line. And that's pretty much how my build went. But I do have a Little gap on the back of the saddle on the left side and in the front on the right side. Wing kinda rocks a little. I already mounted the dowels and drilled for the bolts. Now the wing lines up. If I crank down the bolts really tight it will pull the wing down into the saddle. Just kidding. I will now mix up some micro balloons epoxy and fill the gaps using saran and a little petro jelly.
