Overview
Walksnail Avatar HD Pro Kit is an FPV Digital VTX Kit that pairs the Avatar HD Pro Camera with the Avatar V2 Module (VTX) and a single LHCP antenna, delivering 1080p FPV video with ultra-low latency. The system uses H.265 to provide clear imaging, supports 1080P/60FPS and 720P/120FPS, and the camera’s 1/1.8-Inch Sony Starvis Ⅱ Sensor offers excellent starlight/night vision performance. It supports Gyroflow for smoother footage and includes built-in storage options (8G/32G) for onboard recording at 1080p/720p.
