CUSTOMERS: First aircraft sold October 2001.

COSTS: Wolf US$124,900 including engines (2003).

DESIGN FEATURES: Intended as manoeuvrable twin, able to operate into remote, short airstrips; affordable; easy to build and maintain.
Low-drag fuselage; constant-chord, low-mounted wings, with winglets; pusher engines located close inboard and above wings.
Wing section VH-1 Twin Turbo, purpose developed by Jeff Viken for high lift, low drag laminar flow.

FLYING CONTROLS: Conventional and manual. Fowler flaps immediately outboard of engines. Horn-balanced rudder and elevator.
