Purpose-built for HD digital FPV. Shared dual-platform design for 2-inch high-speed racing and 2.5-inch long-endurance freestyle, breaking the boundaries between frame types.

The Firefly 20PRO/25MINI is a dual-format micro FPV frame tailored for pilots. Designed with the core philosophy of "lowering the entry barrier, reducing duplicate investments, and improving crash resilience," it perfectly fits DJI O4 / O4 PRO / Walksnail / HDZero digital FPV systems. One HD VTX setup can be seamlessly swapped between the 2-inch racing and 2.5-inch freestyle builds.

Crafted from high-strength carbon fiber, featuring a 2.5mm thickened base plate combined with reinforced front arm structures, ensuring ultra-high rigidity and impact resistance while maintaining extreme lightness. From the tool-free quick-release side guards and clean wiring layout to the adjustable shock-dampening camera mount, it comprehensively covers all flight scenarios from beginner entry-level to high-tier racing, letting every pilot focus purely on the flight.
