Siren F5 S2

The Siren F5 S2 is the latest evolution of our popular 5" freestyle frame, optimized for modern FPV standards while maintaining the lightweight agility pilots love. Designed to fully support the latest DJI O4 Pro system, the F5 S2 features a reinforced front-end structure for better durability and crash protection. Its redesigned camera mount and top plate provide an unobstructed FPV view without any frame interference. Like its predecessor, the F5 S2 retains a compact 233mm wheelbase, with optimal prop-to-prop spacing for precise control and maneuverability. It comfortably accommodates 4.9–5.2" props. The frame provides generous rear space for mounting any VTX unit on the market. Our proven C-Lock arm system continues to deliver single-bolt, tool-free arm replacement while enhancing structural integrity and tuning stability. The QUADMULA PS-3 profiled spacer ensures secure mounting of the action cam and TPU parts without stress on components—ideal for confident flying and clean builds
