Aircraft
Svardala Bullet

Before September 1964, Svardala built the prototype Svardala Bullet, 2-seater, side-by-side, flying-boat. The (plywood) hull, landing gear, (fabric-covered) wings, (fabric-covered) empennage and tip floats were similar to contemporary Volmer Sportsman and Anderson Kingfisher. The greatest difference was in in the aft cabin, which vaguely resembled a Republic Seabee. The most striking difference was the short pylon supporting the engine (Continental or Lycoming) and propeller. Because the crankshaft was only a short distance above the (flat) aft fuselage, Svardala installed a 2-bladed, wooden propeller with broad, curved blades.
The Svardala Bullet was sold during the early 1970s and moved to Sherbrooke, Quebec. The new owner complained about poor climb performance. He installed a blown Plexiglas windshield, taller engine pylon and larger diameter propeller.
Apparently, several registrations (most non-official) were tied to the Bullet, including CF-PUY, CF-SYF, CF-PUH, CF-PHU, the latter possibly being the X-1).
Svardala, John
Designer/builder John Svardala immigrated to Canada after World War 2. He settled in Wellandport, Ontario and flew for fun. In 1946, Svardala imported an X-1 airplane and it flew at Hawkesbury, Ontario during the 1979s.
Before September 1964, Svardala built the prototype Svardala Bullet, 2-seater, side-by-side, flying-boat.
SV Aircraft SV X1 Famate-Mantis / Mantis

The SV Xl takes on the sleek lines of the SV series of aircraft from the Veenstra factory. The approach this time is to cater for people who admire the glider lines but would prefer conventional performances. The Xl will have sprung main wheels and a V tail. The owner will have the option to purchase the SV Xl without the sleek cockpit and fly in the breezy aluminium frame that is hidden under the fibreglass skin. Aircraft marketed as Mantis in New South Wales, Australia.
