The Bally B-17 is a one third scale, single seat, homebuilt aircraft, intended as a replica of the Boeing B-17 Flying Fortress.[1]

Design and development[edit]

The Bally B-17 is an original design by Jack Bally. The aircraft is a four-engined, retractable conventional landing gear equipped, low wing monoplane. The fuselage is all riveted aluminum in construction with hexagonal bulkheads. The drawings were modified from a one ninth scale set of radio-controlled aircraft plans. Despite being a scale replica, the aircraft is relatively large for a homebuilt aircraft with 34 ft (10.4 m) wingspan. Most homebuilt aircraft are single engine designs with a few twin engine models produced, making the four engined homebuilt a rarity in itself.[2]
