Designed by Nicholas D’Apuzzo, the aerobatic Senior Aero Sport was available as either a single or two-seater. One prototype, N40304, was designed and built at the request of Rodney Jocelyn as an exhibition aircraft for world champion aerobatic pilot Lindsey Parsons at competitions in Spain. It first flew on 28 July 1960.

Rod Jocelyn completed a PJ-260 Joc-Par Special for entry in the 1964 World Aerobatic Championships in Spain. Powered by a 260 hp Lycoming VO-435-A1F, 27 ft span and 21 ft length, gross weight was 1600 lb. Scothply plastic was used instead of steel spring for landing gear, saving 40 lb.
This sport biplane has a wood-faired steel tube fuselage, wire-braced steel tube tail section, all fabric covered. The fuel supply and the front seat passenger are very close to the center of gravity, so trim is little affected by expending fuel or by the presence or absence of a passenger. A variety of engines can be used from 190 to 260 hp.
Reportedly 7 amateur-built planes up to February 1974. Also seen recorded as Joc-Par. One example is the grand champion homebuilt at the 1968 EM fly-in at Rockford, Illinois.
