The Dream Tundra is a robust, single engine, high-wing monoplane
Monoplane
A monoplane is a fixed-wing aircraft with one main set of wing surfaces, in contrast to a biplane or triplane. Since the late 1930s it has been the most common form for a fixed wing aircraft.-Types of monoplane:...

Washout (aviation)
Washout refers to a feature of wing design to deliberately reduce the lift distribution across the span of the wing of an aircraft. The wing is designed so that angle of incidence is higher at the wing roots and decreases across the span, becoming lowest at the wing tip...

. It is braced by pairs of V-struts attached to the lower fuselage longerons forward of the cabin. Four-position Fowler flaps are fitted. The tailplane and elevators are rectangular in plan, with a cutout in the latter to allow rudder movement. Fin and rudder are likewise rectangular apart from the leading edge, which has a curved fillet. Both rudder and elevators are horn balanced

Behind the engine the cabin, under the wing, is accessed via top hinged doors on both sides. There is a separate, port side door for baggage. The flat sides of the fuselage taper to the tail. Several undercarriage configurations are available; for land based operations the Tundra builder can choose between tricycle and tailwheel gear

. Both use spring cantilever main legs, with large, low pressure tyres for work off soft ground; these legs are positioned at the attachment point of the wing struts for the conventional arrangement and further aft for the tricycle gear. Floats can also be fitted, with their main attachment at the base of the struts and with secondary float struts further aft. Amphibious floats (Montana 2800) may be used. The Tundra may also be equipped with skis. Takeoff (roll) distances with wheels, skis and floats are respectively 125 m, 200 m and 400 m (400 ft, 650 ft and 1300 ft).

The first Tundra flew on 12 May 2001, powered by a 134 kW (180 hp) Textron Lycoming O-360-A flat four engine. Later Tundras have used either the 150 kW (200 hp) Textron Lycoming IO-360 flat four or the 175 kW (235 hp) Textron Lycoming O-540-B4B5

Operational history

By August 2009 35 kits had been sold, with 11 Tundras flying. About 23 have the tailwheel undercarriage and most, apart from the second prototype C-GAGH, retain the curved fin fillet of the first prototype C-GIPN.
