BetaFPV Meteor75 1S HD (HDZero)

A 2022-era build, it pairs the classic Meteor75 frame and 1102 18000KV motors with the HDZero Whoop Lite VTX and Nano Lite camera, coming in at 36.4g bare — about 4g lighter than the Walksnail edition of the same quad, which keeps it in the flyable indoor 1S weight class. The BT2.0 battery connector reduces connector resistance versus PH2.0 for better voltage sag behavior on 1S.

It flies as an indoor/backyard HD trainer, and the factory Betaflight tune on the Meteor75 HD platform is reported as spot-on out of the box, needing no PID changes. HD digital whoops of this generation run 5-8g heavier than analog equivalents, so it carries more momentum and flies less crisply indoors on 1S than an analog Meteor75. Expect about 3.5 minutes on the recommended 450mAh pack.

The ELRS variant carries a true serial/UART ELRS 2.4GHz receiver (F4 1S 5A FC Serial ELRS V2.0) that can be updated to ExpressLRS v3 independently, without reflashing Betaflight — so it stays feature-current with any ELRS 2.4GHz radio, unlike SPI ELRS whoops. The native HDZero video system is plug-and-play with HDZero goggles such as the BoxPro+, delivering clear 720p60 digital video that handles dim indoor lighting well.

The stock Nano Lite is a 720p60-only budget camera — there is no 540p90 low-latency race mode without a Nano90 camera upgrade, and image quality is a step below HDZero's best cameras. It slots in as the budget digital sibling to the newer Meteor75 Pro HD, which superseded it with a lighter 34.9g HDZero build on a larger, more efficient frame. Spares are easy: the Meteor75 frame, 40mm 3-blade Gemfan props, and 1102 18000KV motors are all standard BetaFPV parts sold separately.
