Product overview
The BETAFPV Meteor75 Brushless Whoop Quadcopter (1S HD Digital VTX) is an equipped flight platform for indoor and outdoor digital FPV flying. Its Meteor75 micro frame carries 1102 18000KV brushless motors and 40mm three-blade propellers with a 1.5mm shaft fitting. An injection-molded canopy houses the HD camera, provides 0-45° lens adjustment and uses a hollow design to reduce heat influence on the electronics. Weight without a battery is 40.5g for Walksnail and 36.4g for HDZero; flight times are 3 minutes and 3.5 minutes, respectively.
Video configuration determines the installed transmitter and camera. Walksnail combines the Avatar Mini HD VTX with an Avatar Nano camera, offering 1080P/60FPS recording, 22ms latency and 8 GB of onboard storage. HDZero uses the Whoop Lite Bundle and Nano Lite camera, with 720P/60FPS recording and latency below 19ms. Receiver choices are Serial ELRS 2.4G, SPI Frsky and TBS. Integration capacity depends on the controller: the ELRS board has one UART and excludes external receivers, while the Frsky board provides two UARTs and supports external receivers and PNP use.
The package includes the quadcopter, two 450mAh 1S 30C BT2.0 batteries, a BT2.0 charger and voltage tester, USB cables, four propellers, a screwdriver and screws. The VTX USB cable corresponds to the selected video version. The six-port charger and 40-piece motor screw pack are recommended accessories, separate from these supplied items. During flight, battery voltage must remain at least 3V to keep the HD digital VTX operating. BMI270 gyro support begins with Betaflight 4.3.1, and installing that official firmware requires the Meteor75 HD CLI dump.
