The initial model of the Tundra family was the two-seats-in-tandem tricycle gear Tundra for the US ultralight trainer, homebuilt and European FAI microlight categories. The aircraft features a semi-enclosed cockpit with optional doors and can be fitted with skis or floats.
The Tundra is built from a welded steel cockpit cage with a fibreglass fairing. The tailboom, tail group and wings are of aluminium construction, with the wings and tail surfaces covered in doped aircraft fabric. The wing incorporates a D-cell, Junkers-style ailerons and a single strut layout. Reported construction time for the two-seater is 250 hours.
