Weighing just 16.5g, the Hummingbird V3.1 RaceSpec BNF Mini Drone is crafted for professional FPV racers seeking peak performance in a lightweight design. Its agility and speed make it the ideal choice for competitive pilots looking to dominate the race track.

Compliance is key for serious racers, and the Hummingbird V3.1 RaceSpec features an accurate 25mW VTX, ensuring that your output power stays within race-legal limits. No need to worry about getting disqualified for exceeding power limits—focus on your race with confidence.

In addition to VTX compliance, this drone offers the flexibility of multiple ESC PWM rates: 24kHz, 48kHz, and 96kHz. The factory default is set to 48kHz, which strikes the perfect balance between torque, smoothness, and efficiency. However, racers can easily adjust to 24kHz for more torque or 96kHz for smoother control. Just make sure to use the O-H-5 firmware to prevent any ESC damage.
