Penny for your aerodynamic thoughts? -- This unique teaching tool provides a fantastic demonstration of simple aerodynamics and modeling techniques. Learn how weight, balance, and shape affect how a plane flies. -- Kit comes with a die-cut F-14 TomCat (great for experimental flights) and a die-cut F-15 Eagle (flies fast, far and straight). There's also a sheet of construction paper so you can design your own plane or make spare parts for the die-cuts. -- Includes complete instructions, a fact sheet for each plane, and a penny. |
