HummingBird Whoop Race Spec V2 AIO Flight Controller ELRS 2.4G with 25–400mW VTX

Introduction

The hummingbird whoop race spec v2 aio flight controller is a compact powerhouse for micro FPV. It blends a responsive ELRS 2.4G link with an adjustable 25–400 mW VTX, giving whoop pilots reliable range, clean video, and the agility needed to attack tight lines on indoor and outdoor tracks.

Why it feels faster

Low latency control plus steady video equals confidence. The integrated AIO layout trims weight and reduces wiring, so your tune responds crisply and your build stays serviceable. Push higher output when the venue is noisy, or scale back for close-quarters racing.

Race-ready features

• All-in-one board to simplify builds

• ExpressLRS 2.4G for stable link quality

• 25–400 mW VTX for flexible power and penetration

• Clean routing and sensible pad layout for maintenance

• Firmware-friendly setup for quick PID and rates changes

Built to go the distance

Thermal behavior and durability are tuned for repeated packs. The board handles back-to-back heats without the sag or dropouts that steal confidence mid run.

Who it’s for

Pilots who want fewer compromises in a whoop class rig. If you need podium-grade control in a small frame, the hummingbird whoop race spec v2 aio flight controller delivers the mix of responsiveness and simplicity that keeps your focus on flying.
