HD Digital VTX Walksnail Avatar Mini System

Walksnail Avatar Mini HD VTX uses efficient H.265 encoding and allows video recording in 1080P/60FPS resolution with very low latency of ~22 ms. The VTX is optimized for 3.1–5 V power, weighs about 10 g, and has a built-in 8 GB storage for recording HD video without volume limitations. The Canvas function supports Betaflight OSD display, which can be configured using a remote control. Recorded video files can be exported via USB using a 4-pin connector.

Housing, Camera Protection, and Design

The molded micro-capsule for the HD camera is designed specifically for compatibility with the Walksnail digital VTX; the capsule has an adjustable lens in the range of 0–45° and is made by injection molding for increased strength and flexibility. This design provides better impact protection, reduces the effect of heating on electronics, and allows for decorative finishing.

Motors, Hardware, and Maintainability

New 1102 18000KV motors provide an optimal weight-to-power ratio for 75 mm 1S quadcopters; high RPMs deliver significant thrust, and PCB connectors facilitate replacement or repair in case of cable damage. The Meteor75 HD version flight controller features F4 1S 5A, for ELRS configurations, communication is implemented via Serial ELRS 2.4G (instead of SPI), and the ESC uses the BB51 hardware platform, the gyroscope is updated to BOSH BMI270 for enhanced flight stability.

Pilots can view and export recorded videos from the Walksnail VTX via a 4-pin connector. A user manual is available for quick start: Walksnail Avatar Mini User Manual (PDF).
