InterPlane Starboy
# InterPlane Starboy

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 none seem to have been built.

## 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 8.0 m (26.2 ft) span wing would have had a wing area of 12.41 $m^2$ (133.6 sq ft). The standard engine proposed was the 80 hp (60 kW) Rotax 912UL.

The aircraft was to have a typical empty weight of 245 kg (540 lb) and a gross weight of 450 kg (990 lb), giving a useful load of 205 kg (452 lb). With full fuel of 50 litres (11 imp gal; 13 US gal) the payload for pilot, passenger and baggage would have been 169 kg (373 lb).

The manufacturer estimated the construction time from the planned kit as 500 hours.
