About the Bede Aircraft BD-4

The Bede BD-4 is a two-seat homebuilt aircraft designed by Jim Bede in the late 1960s as one of the first truly successful kit planes for amateur builders. Originally marketed as a low-cost alternative to factory-built aircraft, the BD-4 featured an all-metal construction with a distinctive high-wing configuration and side-by-side seating, making it accessible to builders without extensive fabrication experience. The design proved popular enough that thousands of kits were sold, though the actual completion rate was considerably lower (a common pattern in the homebuilt world).

The BD-4 typically flies behind engines ranging from 108 to 180 horsepower, with the BD-4C variant being the most common, accommodating Lycoming O-320 or O-360 powerplants. Performance varies with engine choice, but a well-built BD-4C cruises around 140 knots and offers respectable cross-country capability with a range exceeding 600 nautical miles. The aircraft's relatively benign handling characteristics and forgiving stall behavior made it attractive to first-time builders, though construction times often stretched to several years. Unlike many kit planes that faded into obscurity, the BD-4 maintained a loyal following, with plans and partial kits still changing hands decades after initial production.
