When you do a lot of talking to aircraft owners, one thing you learn is that owning something unusual is a point of pride; they’re very quick to tell you how few there are in the country. Unless they own a warbird or antique of some sort, very few can say they have the only one in the Australia.

Victorian winemaker Richard Rackley is in that enviable position. His Aerospool WT9 Dynamic is currently the only on the civil register, which–given the capabilities of this Slovakian design–may be aviation’s biggest mystery since Smithy disappeared.

Dynamic construction is largely composite sandwich shell with carbon fibre as the main material. VH-JRR was built in the days when it was common practise not to put a lot of colour on composites, so Rackley’s aircraft is plain white with some burgundy striping to add a touch of flair.

Under the cowling is concealed a 100 HP Rotax 912 with a slipper clutch, swinging a three-bladed 1700 mm diameter Woodcomp prop. The prop is a constant-speed, variable-pitch activated electronically. The combination of these two produces a max speed in the cruise of 132 knots and a rate of climb close to four figures.

Read the full run-down on the WT9 Dynamic on the iPad version of Australian Flying July-August 2013.
