Hummingbird Whoop RaceSpec V2 BNF – The Ultimate Racing Whoop
TheHummingbird Whoop RaceSpec V2is the next evolution of our dedicated racing whoop series, built for professional FPV racers who demandprecision, durability, and peak performance. Designed as the successor to theHummingbird V3.1 RaceSpec, this new version refines and optimizes every aspect of the drone for serious competition. We’ve made significant updates to enhancestability, power handling, and durabilitywithout adding unnecessary weight—because every gram matters when you’re pushing the limits on the track.
Key Upgrades & Features:
Upgraded Flight Controller – Stable & Efficient Power
The MCU is upgraded to AT32 F4 with a 208MHz clock speed(previously 288MHz). This intentional downgrade prioritizesstability and reliability, ensuring consistent performance in demanding race environments.
Double N MOS ESC design(upgraded from N+P MOS) providesup to 18A per channel, delivering superior efficiency and power handling.
No onboard USB portto reduce weight – instead, we’ve included aUSB-C adapterfor tuning when needed.
SmartMax VTX – Power & Compliance in One
Adjustable VTX power up to 400mWwithSmartMax thermal regulation, ensuring the board stays protected while delivering high power.
Precise 25mW output, just like the previous version, keeping you within race-legal limits.No worries about exceeding VTX power limits in competitions.
Race-Optimized ExpressLRS Receiver
Now featuring a UART-based ELRS receiver, allowingrace mode activation, WiFi settings configuration, and seamless performance tuning.
Uses a ceramic SMT antenna, which is not onlylighterbut also significantlymore durable, perfect for intense racing conditions.
Enhanced Build for Durability & Simplicity
Reverse plug-in protectionadded to prevent catastrophic failures due to incorrect power lead soldering—a common issue with non-standard BT2.0 power cable colors.
Bigger solder pads for motorsandno motor plugs, designed forRaceSpec professionalswho prefer direct soldering for ultimate reliability.
Brand-New BeeEye V2 Camera – Lighter, Sharper, Better
Featuring a 10x10mm footprint PCB, reducing weight while improvingcolor accuracy and overall image performance—giving racers better visuals for precise control.
Optimized for Betaflight 4.5.2 RacePro
Preloaded with Betaflight 4.5.2 RacePro firmware, similar to the previous KAACK firmware, ensuringtop-tier race tuning and responsiveness.

Important Notice for Customers:
WARNING: NOT A TOY—FOR EXPERIENCED PILOTS ONLY
The Hummingbird V3.1 RaceSpec BNF Drone is specifically designed for professional FPV racers with advanced skills and technical knowledge. This drone operates like a high-performance race car, built for extreme speed and agility, and requires a pilot who can handle the power and complexity. It is not intended for beginners or casual users. Think of it as the difference between driving a race car versus a standard vehicle—this drone demands experience and expertise to operate safely and effectively.
Please note, physical crash damage is not covered under warranty. The warranty is limited to DOA (Dead on Arrival) units only. To qualify for a warranty claim, the drone must be in good condition, with no physical damage, scratches, missing components, or modifications. Any crashes, improper handling, or modifications void the warranty.
For those who are new to FPV racing, we recommend theHummingbird V4 Standard Version.This version is designed with beginners in mind, offering a more durable frame and easier repairability, making it better suited for pilots learning the ropes.
Important Notice:If you experience issues with your drone,do not flash the firmware. Simply perform a factory reset using the configuration tool (e.g., Betaflight Configurator) and then do an accelerometer calibration. For further assistance, please contact our support team.
