American ultralight aircraft

Capella Javelin General information Type Ultralight aircraft National origin United States Manufacturer Capella Aircraft Corporation Status Production completed History Introduction date 1999

The **Capella Javelin** is a family of [American](/source/United_States) open cockpit, high wing, [tractor configuration](/source/Tractor_configuration), [conventional landing gear](/source/Conventional_landing_gear)-equipped [ultralight aircraft](/source/Ultralight_aircraft) that were produced in kit form by [Capella Aircraft](/source/Capella_Aircraft) of [Austin, Texas](/source/Austin%2C_Texas) and intended for [amateur construction](/source/Homebuilt_aircraft).[1][2][3]

The single seat Javelin I was designed to comply with the American [FAR 103 ultralight regulations](/source/Ultralight_aircraft_(United_States)), including that category's maximum 254 lb (115 kg) empty weight.[1][2][3]

Capella Aircraft went out of business in late 2007, and the type is no longer in production.

## Design and development

The Javelin was introduced circa 1999 and was intended to appeal to pilots who wanted to experience totally open-air flight.[1]

The design features an open frame [fuselage](/source/Fuselage) of welded [4130 steel](/source/4130_steel) tubing, with the pilot's and passenger's seats bolted to the frame. The [horizontal stabilizer](/source/Horizontal_stabilizer) and [tail fin](/source/Vertical_stabilizer) are also constructed of welded steel tubes. The wing is framed from riveted [aluminium](/source/Aluminium) tubing with all flying surfaces covered in doped [aircraft fabric](/source/Aircraft_fabric). The wing is equipped with full span [ailerons](/source/Aileron).[1]

The conventional landing gear includes sprung-steel main gear and a similarly sprung steerable tail wheel. The open cockpit design provides good visibility while [taxiing](/source/Taxiing).[1]

The standard engine supplied by the manufacturer for the single seat version was the 28 hp (21 kW) [Rotax 277](/source/Rotax_277), but it was reported that the aircraft was underpowered with that engine installed. The throttle control is of a unique [motorcycle](/source/Motorcycle) grip type.[1]

Original factory kit options included a cockpit pod and windshield, brakes and steel tube [powder coating](/source/Powder_coating).[1]

The single-seat Javelin was developed into a tandem two seater, designated the Javelin II and then further developed into the T-Raptor ultralight trainer. The T-Raptor uses a wider and more enclosed fuselage, with optional bubble-windowed doors, to allow cool weather flying and was intended to be marketed to ultralight schools.[3][4]

## Variants

**Javelin I**
- Single seat open cockpit ultralight powered by a 28 hp (21 kW) [Rotax 277](/source/Rotax_277) engine.[1][2][3]

**Javelin II**
- Two seats-in-tandem open cockpit ultralight trainer powered by a 50 hp (37 kW) [Rotax 503](/source/Rotax_503) engine. It was reported as being in development in 1998 and forecast to be available at the end of 1998.[2][3]

**T-Raptor**
- Two seats-in-tandem ultralight trainer powered by a 50 hp (37 kW) [Rotax 503](/source/Rotax_503), 64 hp (48 kW) [Rotax 582](/source/Rotax_582) or 60 hp (45 kW) [HKS 700E](/source/HKS_700E) four stroke engine. The T-Raptor has an expanded-width steel cage to provide a more enclosed cockpit and is a development of the Javelin II.[5]
