This type of radio-controlled model aircraft represents a distinct design where the wings constitute the primary, and often only, airframe structure. Such models are typically sold as unassembled collections of parts, requiring construction and configuration before they are flight-ready. These collections commonly include pre-cut foam or balsa wood components, hardware, and instructions necessary for assembly.
The appeal of this configuration stems from its potential for aerodynamic efficiency and inherent stability. Its design can lead to reduced drag and increased lift, potentially translating into greater speed and longer flight times compared to conventional model aircraft. Historically, this design has been explored for its potential in both high-performance aircraft and stealth technology due to its low radar cross-section characteristics.
