The Hatz CB-1 Biplane is a two place with generous wing area - enough to make flying a pleasure on as little as 85 HP. Low landing speed, slow flight capabilities, plus a comfortable 90 mph cruise has been combined in an airplane still small enough for the homebuilder to undertake. Aircraft are plans built but many parts are available.

A straight-forward design with simple details and a minimum of time consuming jig work is the result of many hours of planning and testing.

Construction: steel tube fuselage and tail; spruce spars with truss rib wing construction; bungee shocks for the gear; 6 x 6 wheels with brakes; dual controls; space for overnight bag on shelf in front cockpit; fuel capacity 33 gallons in two tanks, or 20 gallons in one tank (centre section).
