It is almost entirely of riveted aluminium construction, though flying surface tips are composite, and is laid out in conventional high-wing, single-engine, form.

It is braced by pairs of V-struts attached to the lower fuselage longerons forward of the cabin.

Several undercarriage configurations are available; for land based operations the Tundra builder can choose between tricycle and tailwheel gear.

[4] The first Tundra flew on 12 May 2001, powered by a 134 kW (180 hp) Textron Lycoming O-360-A flat four engine.

[5] Other alterations were made to the later aircraft, principally to the undercarriage (the prototype had wheels mounted on faired V-struts with bungee sprung half-axles), to the cabin doors for ease of access, to the tailplane and fin for ease of building and by the addition of a double cabin floor for better sound insulation.
