strut-braced
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in ...

, with assistance from Guy Storer, who was head of the
Raspet Flight Research Center at that time. The designation of "CBS-1" indicates "Carter-Bennett-Storer". The aircraft was first registered with the
Federal Aviation Administration in 1958. Bennett went on to head the Aerophysics Department at MSU by the early 1980s.
The aircraft is constructed with a steel tube
fuselage, wooden wings and tail surfaces, all covered in doped
aircraft fabric. The wing is supported by a single
strut. The wing design was based on the
Schultz-Midwest MU-1 wings, but with a greater wingspan, employing a
NACA 4415
airfoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine.

. The
tailplane was based on that of the
Laister-Kaufmann LK-10A, while the fin and rudder shapes were scaled down from the
Schweizer SGS 2-12. The CBS-1 has no spoilers or other glide path control device.
The landing gear was originally a take-off dolly and the aircraft landed on a fixed skid. This was later replaced with a fixed monowheel.
