Hummingbird 200 RaceSpec Flight Controller – AT32F435 20x20 FC with Built-in ELRS 2.4GHz for FPV Racing

The Hummingbird 200 RaceSpec Flight Controller is a compact 20x20 FC built from the ground up for competitive 5” FPV racing. Designed in collaboration with top pilot Kyle Buell (Twidgit) and refined over months of on-track testing, this board is race-proven, crash-tested, and ultra-efficient.

Powered by the AT32F435 MCU running at 288MHz, this flight controller offers faster processing than traditional F722-based boards, resulting in quicker loop times and more responsive handling. The ICM-42688 gyro, paired with its own dedicated LDO regulator, ensures clean, low-noise gyro data and smooth flight characteristics that meet the standards of serious racers.

The board also features a built-in UART-based ExpressLRS 2.4GHz receiver with dual ceramic patch antennas and a TCXO oscillator, ensuring a strong, reliable link without the need for external receiver modules. This built-in setup reduces wiring complexity and increases crash resistance, letting you focus on winning races—not replacing antennas.

Designed for clean integration, the Hummingbird 200 FC includes direct plug support for HDZero VTX, dual BEC outputs (10V 2A and 5V 2A), and all necessary pads for LEDs, buzzers, and GPS. With race-focused layout and durability, it’s the flight controller serious FPV racers have been waiting for.
