Things You'll Need
Instructions
Assemble your glider according to the instructions included in the balsa wood glider kit, usually available at any hobby store.
Test the flight readiness of your car by attaching it to the glider with a rubber band. If you've got the right materials, your glider should be able to support the added weight of your toy car. If your balsa wood glider doesn't produce as much lift as you need to support the weight of the miniature car, you'll need a larger glider.
Attach your toy car to the glider, first locating the best location to glue the two together. For the most part, you'll find that the most stable part of your glider is directly beneath the wings. You will, however, want to make sure weight is distributed effectively between the front and rear of the aircraft. If not, your flying car will either nosedive or fall tail-first from the sky. Again, a process of trial and error will probably be the most effective way to make an appropriate determination of balance. If necessary, use your rubber bands to test the optimum position for the car along the underside of the glider.
Glue your glider to the roof of your toy car, using toothpicks to ensure stability during the drying process.
