The Hummingbird Whoop RaceSpec V2 is the next evolution of our dedicated racing whoop series, built for professional FPV racers who demand precision, durability, and peak performance. Designed as the successor to the Hummingbird V3.1 RaceSpec, this new version refines and optimizes every aspect of the drone for serious competition.
We’ve made significant updates to enhance stability, power handling, and durability without adding unnecessary weight, because every gram matters when you’re pushing the limits on the track.
Upgraded Flight Controller – Stable & Efficient Power
The MCU is upgraded to AT32 F4 with a 216MHz clock speed(previously 288MHz). This intentional downgrade prioritizesstability and reliability, ensuring consistent performance in demanding race environments.IF YOU CANNOT GET INTO DFU, PLEASE INSTALLAT32 DRIVER
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.
This ELRS Receiver is not official approve by ELRS team because the ESP8285 are no longer adapted by the new ELRS design guideline. If you need to update the firmware.
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 4.5.1 RacePro
Preloaded with Betaflight 4.5.1 RacePro firmware, similar to the previous KAACK firmware, ensuringtop-tier race tuning and responsiveness.
