"Models that fly need to be more than just good-looking. They need to be shaped just right to move through the air. This engaging introduction to model making explains aerodynamics, the mathematics of scale, how gliders and models propelled by rubber band, electric motor, fuel, or a rocket work, and the difference between building from a kit and building from scratch. Tips on shaping wings, choosing body materials, and weather-proofing help build fine-motor skills. Young readers are encouraged to build patience, concentration, perseverance, and problem-solving."--.
