Built by Colin Winton and his son Scott, the Grasshopper was designed to fit under Air Navigation Order 95.10, which limited the empty weight of such aircraft to less than 100kg. Power came from a 432cc Robin engine. The Grasshopper was developed in the late 1970s well before a system of aircraft registration for such aircraft was formally established. The museum's aircraft was based in Western Australia where it made several long distance flights but by 1981 had been grounded. It passed to the QAM in 2008.
