The final design from prolific Dutch-Australian ultralight aircraft designer Sander Veenstra. He was killed on March 6, 1985, testing a version of the SV11 Farmate called the Rustler. Veenstra had been manufacturing ultralights for five years. The SV14 was the only Veenstra design with a tractor propeller and intended for training. The system for registering ultralights came after Veenstra's death and the SV14 was never registered.

The Viva was designed by Ron Wheeler, better known for his Scout ultralight. No Vivas appeared on the recreational aircraft register and it is not known how many were built. There is a grainy photo of one in flight with "95-10", which was the Australian regulation covering ultralights at the time, painted on the fuselage and "001" on the fin.

Registered in 1987. Registration expired in 2010. The last of a series of ultralight flying boat prototypes. It differed from its predecessors by having twin engines (push-pull), retractable undercarriage and an enclosed cockpit.

Popular Canadian aircraft from the 1980s. Powered by two 5.5hp 100cc engines with plastic propellers. Registered in Australia in July 1988.

Second of three improved, heavier production versions of the Ligeti Stratos ultralight. Designer Charles Ligeti lost his life when the first one (MK-001) crashed on its first flight on September 22, 1987. The second, MK-002, pictured, crashed when its engine lost power on take-off during test flying at Mangalore, Victoria, on July 10, 1988. Pilot seriously injured. Stratos project stopped. A third (MK-003), which is just a fibreglass shell, is displayed at Ballarat. All three production aircraft allocated ultralight registrations, since lapsed.

The Hornet first flew in South Australia on March 8, 1979. Three prototypes and three production aircraft built. The museum example is one of the production aircraft and last flew in 1981. The pusher engine drives a shrouded propeller. Free Flight, which had made hang-gliders, went out of business after the Hornet program ended.
