HGLRC Petrel 75Whoop V2 1S Brushless Indoor FPV Drone (ELRS)

The HGLRC Petrel 75Whoop V2 is a 1S brushless tiny whoop for indoor flying and light outdoor sessions, and an approachable first whoop for new FPV pilots. This is the ELRS version: an SPI ELRS 2.4GHz receiver is built into the flight controller, so it binds directly to an ELRS radio.

Key features

• SPECTER 10A 5-in-1 board combines an STM32F411 FC with BMI270 gyro, 4-in-1 ESC, analog VTX and receiver

• RunCam Nano 4 camera and a VTX adjustable from pit mode through 25, 100 and 400mW across 48 channels

• SPECTER 0802 21000KV motors with plug-in leads, so a motor swaps without soldering, spinning Gemfan 1610 two-blade props

• About 27 g and roughly 5 minutes per 1S 450–550mAh HV pack with an A30 plug

The SPI receiver does not support the ELRS D250/D500, F500/F1000 or Full Res packet rates. If it will not connect, set the transmitter module's packet rate between 50Hz and 500Hz and avoid modes starting with D or F.
