The Sorrell Guppy, which first flew in 1967, is an American single-seat homebuilt cabin biplane. Measuring 4.6 meters long with a 6.5-meter wingspan, this aircraft achieves 128.7 km/h. The Guppy represents homebuilt aircraft movement during recreational aviation expansion, emphasizing owner construction and practical utility. Its biplane configuration and cabin accommodation reflect compromises between weight reduction and weather protection. The Guppy's modest performance and compact proportions position it for recreational flying and personal transportation within visual-flight-rules operations.
