How To Make Balsa Wood Glider

Following you will know more about the Balsa wood. Balsa, a lightweight and pliable wood from South America, is ideal for a variety of hobby and model-building purposes. However, balsa wood is best known for its featherweight qualities, perfect for the construction of gliders and model airplanes that can actually be flown. There are several options for building an airplane from balsa wood, and, whether built from a kit or made purely from scratch, constructing a glider from balsa wood is relatively easy. In fact, it's possible to produce an airworthy glider within a few hours.
Decide on the type of glider you'd like to build. Choose from two major types of gliders ---those built for speed, and those built with flight duration in mind. Gliders intended to achieve high speed will usually have wings in a triangular, swept-back position, while gliders meant to stay aloft for long durations will have longer, straight-wing configurations.
Prepare the template for the glider you'll be building. If you have purchased a kit, the template nvnwzhiq will already be printed and ready to use. If you're designing the glider yourself, however, draw the shapes of the pieces (wings and tail pieces) on a sheet of standard white paper. Either computer printer paper or sheets from a notebook will be sufficient.
Prepare your work surface. Lay the balsa wood sheets on top of a large cardboard or cork sheet, then place the template sheet over the balsa wood. Use straight pins to hold the template in place over the balsa wood.
Cut the wing and tail pieces from the balsa wood sheets. Cut through the template sheet and into the wood, following the guidelines drawn on the template. When you remove the template paper, the wood components should be cut completely from the larger wood sheet.
Prepare the fuselage, or body, of the glider for assembly. Measure the base width of each wing and tail piece component, then cut corresponding slits and notches in the length of balsa wood that will be the glider's body.
Assemble all of the glider's components. Glue each component onto the glider's body individually, allowing enough time for the connection to dry before attaching another piece. At this point in the building process you can begin to apply penny nose-weights to the glider. Use tape to affix each penny to the nose of the glider.
