Going to have to study my plans more. I was thinking of a bit metal fitting on both spars that would connect the the center section to the wing. Sort of like a Jodel, although I must admit that I'm not sure exactly how they do it on that plane. > Access to the end of the spar pin is complicated > by the box, unless you make a long enough spar pin to go through both > both the webs in one spar. Hmmm, didn't think of that one. > Finally, if you project the box spar all the way through the cabin, > you'll see that it needs to occupy some of the space currently used by > the control stick and linkage. Again, I gotta memorize those plans. I think I may be ok with this though as I am already messing up a perfectly good plane by trying to make it into a two-holer. I'm planning on dual controls, so I have more leeway with where the control sticks and linkages are going. > None of these is unworkable (after all, there has been at least one such > Fly Baby built) but could really, REALLY slow up your building process > as you try to solve these problems. Well, its taken me a year to just study the plans. I've yet to get a proper shop togather. And I would like to get my shop assistant out of diapers. By the time I get the thing done, I'd about be ready to be buried in it. Fortunately, I've already got something to fly. This is something to build. Frank Stutzman Hood River, OR
