BAYCK RC dog crossing machine frame, with Guofeng science and technology aesthetics as the core design concept, integrates modern crossing machine engineering technology, and creates a lightweight FPV frame with both color value and performance. The fuselage adopts streamlined bionic structure design, which takes into account structural strength and flight flexibility. The layout of heat dissipation openings is reasonable, which effectively improves the heat dissipation efficiency during flight. Lightweight design reduces the load of the fuselage and adapts to various FPV flight scenes such as racing speed and flower flying. There is no physical object yet, so we can cooperate in development and production.
