My second test and reaction of the DJI O4 Air Unit with the Open Racer frame, now flying through race gates! 🎯 Comparing Crossfire vs ELRS 500—was Crossfire even worth it? 🤔 Plus, how does the DJI O4 100PFS stack up against HDZero 90FPS with latency? Testing at an FPV race, seeing if it interferes with other pilots’ signals. 📡 Is the DJI O4 the best all round FPV system and can race?
