China Copies Nasa Engineer
A competition rubberband glider is copied and sold by Ali Express for $0.90 each. A pretty good project for a 3-5 grader with automatic winder. The rubberband is housed inside the tube or green straw. An airfoil is encouraged by the wing mount. If you have built flitetest airplanes, you can use their tecniques to extend the airfoil down the wing.
