The Larson F-12 Baby was a single engine, single seat sports biplane built in the US in the early 1960s.
Design and development
The Baby was a single bay biplane with stagger. The wings were wooden structures with two spars and fabric covering; the upper wing had 1° of dihedral and the lower one 3°. There were ailerons on both wings, with aluminum frames and again fabric covered. The fuselage and empennage were fabric covered, welded steel structures. It had fixed conventional landing gear with rubber sprung main legs, aluminum wheels with brakes and a sprung tailwheel.[1]
The Baby was powered by an 85 hp (63 kW) Continental C85 air-cooled flat four, its fuel tank in the fuselage behind the engine and in front of the single seat, open cockpit.[1]
