I can agree with everyone else here too. You did share a lot of good ideas. Like i said i think eariler in this thread that i also used the nylon bolts to bring the L.E. gap near the fuse. But I eliminated the dowl all together. Dont know if that was a good idea or what? I used the approaiate sized threaded insert where the dowl was. It seems to have a lot of strength when i push and pull the wing around. I dont think i could use the dowl again the way ive done it.
For my belly pan i just epoxied 6 inch long bass wood strips to the inside and used 4-40 blind nuts and bolts. I kinda rushed where i was drilling the holes, and now i got a little gap where the front of the belly pan is. Thinking i can build up that area with some balsa and cover it with some of the supplyed covering. That will also help seal the area from fuel + exhaust since im routed my muffler to the underside of the cowl. (Well thats my plan though)
