The '''Capella Javelin''' is a family of [[United States|American]] open cockpit, high wing, [[tractor configuration]], [[conventional landing gear]]-equipped [[ultralight aircraft]] that were produced in kit form by [[Capella Aircraft]] of [[Austin, Texas]] and intended for [[Homebuilt aircraft|amateur construction]].<ref name="Cliche">Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page B-33. Cybair Limited Publishing, 2001. {{ISBN|0-9680628-1-4}}</ref><ref name="KitplanesDec1998">Downey, Julia: ''1999 Kit Aircraft Directory'', Kitplanes, Volume 15, Number 12, December 1998, page 40. Primedia Publications. ISSN 0891-1851</ref><ref name="Aerocrafter">Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 137 & 347. BAI Communications. {{ISBN|0-9636409-4-1}}</ref>
The single seat Javelin I was designed to comply with the American [[Ultralight aircraft (United States)|FAR 103 ultralight regulations]], including that category's maximum {{convert|254|lb|kg|0|abbr=on}} empty weight.<ref name="Cliche" /><ref name="KitplanesDec1998" /><ref name="Aerocrafter" />
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.<ref name="Cliche" />
The design features an open frame [[fuselage]] of welded [[4130 steel]] tubing, with the pilot's and passenger's seats bolted to the frame. The [[horizontal stabilizer]] and [[Vertical stabilizer|tail fin]] are also constructed of welded steel tubes. The wing is framed from riveted [[aluminium]] tubing with all flying surfaces covered in doped [[aircraft fabric]]. The wing is equipped with full span [[aileron]]s.<ref name="Cliche" />
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]].<ref name="Cliche" />
The standard engine supplied by the manufacturer for the single seat version was the {{convert|28|hp|kW|0|abbr=on}} [[Rotax 277]], but it was reported that the aircraft was underpowered with that engine installed. The throttle control is of a unique [[motorcycle]] grip type.<ref name="Cliche" />
Original factory kit options included a cockpit pod and windshield, brakes and steel tube [[powder coating]].<ref name="Cliche" />
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.<ref name="Aerocrafter" /><ref name="ClicheTRaptor">Cliche, Andre: ''Ultralight Aircraft Shopper's Guide'' 8th Edition, page B-105.

==Variants== ;Javelin I :Single seat open cockpit ultralight powered by a {{convert|28|hp|kW|0|abbr=on}} [[Rotax 277]] engine.<ref name="Cliche" /><ref name="KitplanesDec1998" /><ref name="Aerocrafter" /> ;Javelin II :Two seats-in-tandem open cockpit ultralight trainer powered by a {{convert|50|hp|kW|0|abbr=on}} [[Rotax 503]] engine. It was reported as being in development in 1998 and forecast to be available at the end of 1998.<ref name="KitplanesDec1998" /><ref name="Aerocrafter" /> ;T-Raptor :Two seats-in-tandem ultralight trainer powered by a {{convert|50|hp|kW|0|abbr=on}} [[Rotax 503]], {{convert|64|hp|kW|0|abbr=on}} [[Rotax 582]] or {{convert|60|hp|kW|0|abbr=on}} [[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.<ref name="TRaptor">{{cite web|url = http://www.capellakitplanes.com/traptor/trptr.htm |title = About The T-Raptor - The 'Cub' for the next Millennium! |accessdate = 9 May 2010|last = Capella Aircraft|authorlink = |date=March 2004}}</ref>
