The Alexander Schleicher K4 was designed in the mid 1950s by Rudolf Kaiser as a club training glider and several hundred were built. The Australian Gliding Museum’s K4, VH-IKK, serial number 55, was built in 1957 and purchased by the RAF Air Training Corp. U.K. After some years it was sold to a New Zealand Gliding Club and in 1990 with over 4800 hours, number of launches unknown, it was purchased by the Brisbane Valley Soaring Club and in 1994 was transferred to the Far North Queensland Soaring Centre who operated it from the Mareeba airfield. On 9 January 2000 it was donated to Vintage Gliders Australia by Kevin Sedgman at a presentation ceremony with Alan Patching receiving the glider during the Rally at Lake Keepit. It has been flown regularly at vintage glider rallies and on several occasions at Museum open days. However, it has subsequently been grounded on account of potential structural defects. VH-IKK is one of two K4s in Australia, the other being VH-XJP which is believed to be in storage in Queensland in a damaged condition. When restored, this exhibit will be representative example of the AS-K4 glider-sailplane type.Tandem two seat high wing strutted glider consisting of wood with plywood and fabric wings, tailplane / elevators, fin / rudder, and tubular steel framed, fabric covered fuselage.

The Slingsby T53 glider was designed by J. Sellars in the 1960s as an easily maintained two seat trainer suitable for RAF Air Training Corp use and for sale in the USA and Australian markets where wooden gliders were becoming less popular. The Slingsby T53 prototype first flew in 1967. The T53B version has a conventional fixed tailplane with elevator instead of the all-moving tailplane of the original type. The “B” version also has ailerons of narrower chord and lacks wing flaps. Further changes were made to the fin (extended above the tailplane) for the final “C” version. Production of the T53 at Slingsby was disrupted by a fire at the factory in 1968. As a consequence the contract to supply 40 of the type to the RAF was cancelled and only a relatively small number (possibly 27) were made by Slingsby before the project was discontinued. The rights were later sold to Yorkshire Sailplanes. It designated the glider as the YS53 Sovereign – only a few were produced (possibly 3). The Australian Gliding Museum’s example is a type “B” model. It bears serial number 1686 and was manufactured in 1967. It was registered in Australia as VH-GUB in name of Boonah Gliding Club, Boonah, which is about 90 kilometres south west of Brisbane in Queensland. Locally it was called “the Bomber”! This exhibit is a representative example of the Slingsby T53 sailplane type.
