4. Use the wing template and a sharp toothpickto mark the holes for the spars on the topsurface of the lower wing and the bottomsurface of the upper wing. Note that thefront edges of the wings curve down. In thispicture the upper wing in the backgroundneeds to be turned upside down.4.5. Dip toothpicks in glue and insert them in thespar holes now marked in the lower wing.Try not to push them all the way through thewing. Be sure they are standing up as straightas possible. The upper wing in the foregroundof this picture is upside down (the curved edgeis curving up).5.6. Now, with both the upper and lower wingsupside down (the edges should be curvingup at this point), insert the back row of sparsinto the underside of the top wing. Use themarked holes as a general guide, but keep thespars straight and evenly spaced. Put a littleglue on each to keep them in place as shownin the picture. Now join the front spars to thetop wing, remembering to keep them straight,and fasten them with dabs of glue. This takessome effort to get everything in the right placeand is easier to do with two people.6..Learning to Fly: The Wright Brothers’ Adventure50EG–2002–12–007–GRC
