The InterPlane Starboy was a proposed Czech homebuilt aircraft designed by InterPlane Aircraft of Zbraslavice. The aircraft was intended to be supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction, but it has seemingly never entered production.Purdy, Don: AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition, page 353. BAI Communications, 15 July 1998. {{ISBN|0-9636409-4-1}}
Design and development
The Starboy design featured a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.
The aircraft was to have been constructed of a combination of aluminum and composite materials. Its {{convert|8.0|m|ft|1|abbr=on}} span wing would have had a wing area of {{convert|12.41|m2|sqft|abbr=on}}. The standard engine proposed was the {{convert|80|hp|kW|0|abbr=on}} Rotax 912UL.
The aircraft was to have a typical empty weight of {{convert|245|kg|lb|abbr=on}} and a gross weight of {{convert|450|kg|lb|abbr=on}}, giving a useful load of {{convert|205|kg|lb|abbr=on}}. With full fuel of {{convert|50|L}} the payload for pilot, passenger and baggage would have been {{convert|169|kg|lb|abbr=on}}.
The manufacturer estimated the construction time from the planned kit as 500 hours.
