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.
