Fun at Weekend!

The wing's length measures at 59 cm, and its weight is a mere 35 grams. Remember to carefully adjust the Center of Gravity (CG) point, which should be located one-third of the wing chord from the leading edge, close to the bottom of the wing. Ensure your construction process is simple and enjoyable; if you're lucky enough to encounter thermals, take advantage of their updrafts for added fun! For materials, you will need balsa wood in thicknesses of 1.5 mm and 2 mm, as well as hardwood or laminated balsa hard type for the wing structure. Alternatively, use two layers of 1.5 mm balsa to create a 3 mm thick piece, or combine a 3 mm piece with a 2 mm one for a 5 mm thickness. Plywood (or directory cover at 1 mm thickness) is also required. Additionally, you'll need kitchen stretch film, an iron or steel weight balance with a diameter of 6x5 mm, a sewing needle with a piece length but a diameter of 1 mm and thickness, an M2x8 screw (optional, for added stability), UHU Hart glue (the best choice for bonding balsa wood), and transparent single-sided adhesive tape in widths of 8 mm, 10 mm, or 12 mm.
