Designed by Robert Chase, the C100-S made its first flight in 1968. It uses a 3-piece wing with an airfoil 15% thick and no aerodynamic twist. Wood and Styrofoam are used in the construction of the wing (as well as the tail), but the entire surface and the stress- bearing material is fiberglass. The fuselage is of all-metal stress-skin construction, with a skid and fixed wheel.
