The C100-S project was started by Chase in 1962, with prototype construction commenced near the end of 1963. The resulting aircraft was first flown in 1968.[1][2]
The aircraft is built from a combination of wood, styrofoam, aluminium and fiberglass. The semi-tapered wing is built from wood and styrofoam, covered with stress-bearing fiberglass. The wing is tapered outboard of the mid-span point. The wing spar is built up from 14 layers of fiberglass and epoxy resin at the root and is a box-style spar that occupies 40% of the wing chord. The wing is constructed in three pieces, a center-section and wing tips and features Schempp-Hirth dive brakes. The wing is 15% thick and employs a NACA 64(3)-615 laminar flow airfoil.[1][2]
The fuselage is built from aluminium and features stressed skin construction. The landing gear is a fixed monowheel. The pilot's seating position is semi-reclined. In addition to the dive brakes the pilot has a tail-mounted drag chute available.[1][2]
Only one C100-S was ever built and it is registered in the experimental amateur-built category.[1][2][3]
The former owner of the glider, Dr. Richard Sisley of Los Angeles, California, reported in 1983 that the aircraft had excellent thermalling flight characteristics.[2]
In May 2011 the sole example produced was still registered with the Federal Aviation Administration.[3]
