GLASTAR

TYPE: Side-by-side kitbuilt

PROGRAMME: Designed by Arlington Aircraft Developments and produced until 2000 by Stoddard-Hamilton. Prototype (N824G) first flew 29 November 1994; deliveres of kits started 1995. Over 1,400 hours flown by December 1998. Prototype converted to tailwheel configuration and then back to tricycle. Chosen by EAA as flagship aircraft for Young Eagle junior pilot scheme; first customer-built aircraft completed in July 1996. Early examples had a 93 kW (125 hp) Teledyne Continental IO-240. "Jumpstart" kits introduced in 2003, reducing build time by estimated 400 hours.

FAA certified version being built in Germany as OMF Symphony. Four-seat, Four Winds versions produced in US.

CURRENT VERSIONS: Glastar: Basic model; as described.
Sportsman 2+2: Introduced mid-2003 in anticipation of US Sport Pilot legislation; strengthened wings, saftey cage and landing gear. First kit delivered October 2003 to builder in New Hampshire.

CUSTOMERS: Over 900 kits sold in 16 countries up to October 2002; over 300 flying by February 2002. Total of 205 registered in USA alone by December 2001 increasing to 229 in October 2002.

COSTS: Glastar US$24,705; Sportsman 2+2 US$31,950 per kit, excluding engine, instruments, upholstery and paint (2003).

DESIGN FEATURES: Conceived as inexpensive two-seat personal lightplane with wide performance envelope. Convertible landing gear, float compatible. Wings fold (one-person, three-minute task) and horizontal tail surfaces removable for compact hangarage or for trailer mounting. Quoted build time 1,500 to 2,000 hours. "Jumpstart" options introduced in November 1998 to reduce time by half; wing kits for this option are assembled in the Czech Republic.
Braced, high wing of constant chord, unswept. Tailplane has root extensions; tail, sweptback fin. Wing section LS(I)-0413.

FLYING CONTROLS: Conventional and manual. Frise ailerons; Fowler flaps. Elevator tab for pitch trim. Ground-adjustable tab on ailerons. Three-position flaps: 0,20 and 400. Vortex generators added to wings in front of ailerons and at wingroots, and root strakes to horizontal stabiliser. Optional electric elevator trim.

STRUCTURE: Fuselage construction of GFRP with 4130 steel tube frame surrounding cockpit section. Wings and tail surfaces of 2024-T3 aluminium. Two-spar wings have six full ribs per side, plus stiffeners.

LANDING GEAR: Fixed nosewheel type with spats; steerable tailwheel or Aerocet 2200, Wipline, Bilmar and Montana float versions; no differences in airframe among landing gear alternatives. Tailwheel (15 cm; 6 in tyre) conversion effected in 3 hours; choice of three mainwheel sizes: 5.00-5 (with speed fairings), 6.00-6 and 8.00-6. Optional Scott 3200 20 cm (8 in) tailwheel with larger mainwheels.
