I can't think of many times I've actually seen nylon screws actually shear and save fuselage/wing structure. I've seen plenty (including mine) save fuselage/gear damage (beefier structure there). I've read about a trick where you drill a hole through a 1/4-20 to allow them to shear more easily, but never seen anyone actually do it. But I think I'd choose 10-32,....and tees, on a 39" ws. ... nylon, just outta habit, plus they seem to have larger heads. I like using tee nuts instead of tapped hardwood, easier. I'd just use a plywood disc, 1/16", under the bottle heads. That's another reason to go larger diameter,... smaller would tend to "cut" the surrounding wing structure on rough, wing dragging landings, loosening up the hole, loosening the wing on the fuselage, especially if you use metal screws.
Keep up the good work, hope you are healing fast. At least you have lousy weather to keep you inside as well,... designing. 82 degrees and higher here, just too hot for me. Be home soon.
