| The Twin Astir was a two-seat development of the
Standard Class Astir CS. The prototype Twin Astir first flew on 31
December 1976. VH-IKM is one of the original production aircraft and
first flew on 28 December 1977. Grob's early model Twin Astirs have
a retractable landing gear that retracts by folding up to the left and
lying horizontally under the rear seat. Water Ballast tanks
are also fitted. In contrast to
later G 103 models, the Twin Astir has the main wheel ahead of the centre of gravity, and does not have a nose wheel.
Manufactured with a tailskid, VH-IKM was fitted with a tail wheel in April
1978 upon arrival in Australia. |

| The DG-500 comes in a number of sizes which all
share the same basic fuselage. The 500T Elan Trainer, which first flew in
1989 has an unflapped 18 m. wing without provision for Water Ballast;
retractable gear is an option. The front cockpit design has been purposely
made similar to that of the DG-300 Club. The higher performance versions (DG-50022 Elan and DG-500 M) have a 22 m flapped wing and are,
respectively, unpowered and self-launch models. VH-XON is the powered
model (DG-500M) and has a liquid cooled Rotax powerplant on an
electrically retracting pylon, digital engine instrumentation (DEI) and Water
Ballast reduced to 100 kg / 220 lb and comes with a steerable
nosewheel. The DEI, which has instrumentation in both cockpits, shows rpm,
temperatures, pressures and fuel quantity as well as controlling the
amount of fuel injected by the electronic fuel system. Engine retraction
is automatic once the propeller has been stopped and centred. All
22m ships, which have a four piece wing, have retractable gear as
standard. Performance of the 500M is similar to the 500/22 Elan, but empty
and Gross weights are 565 kg./ 1,246 lb And 825/1,819 lb
Respectively. |

fibre wing shell, winglets, T-tail, wing and vertical tail fin water ballast
systems, retractable and sprung landing gear, and upper wing surface air
brakes. The LS8-st may be operated in 15m or 18m span and winglets in
both versions. The self-sustaining system in the fuselage consists of an
extendable aircooled twostroke twin cylinder engine with fixed pitch
propeller. This powered sailplane has been produced using the latest
technology of industrial fibre design (Glass-, Aramid- and Carbon fibres).
It is designed for competition flights – high performance combined with
excellent handling characteristics.
