Description

The Walksnail Avatar system represents a high-performance digital FPV solution, engineered to replace traditional analog video links. The Avatar HD Nano air unit integrates a 1/2.7-inch CMOS sensor and a powerful VTX into a remarkably compact 3.5g package, making it ideal for lightweight micro and 3-inch FPV drones. Its 170-degree FOV lens with an F2.0 aperture ensures excellent light capture in varied conditions.

The accompanying Avatar VRX ground station module is the heart of the receiving system. Its four-antenna design employs advanced diversity algorithms to maintain a stable video link at distances up to 4km. With HDMI output for zero-compression viewing and full Betaflight OSD support via Canvas Mode, it provides a seamless interface for both immersive flying and detailed system telemetry monitoring.

Key Features

  • Avatar HD Nano Air Unit: Ultra-compact 3.5g camera/VTX combo with 1080p/60fps sensor and 170° FOV lens.
  • Dedicated VRX Module: Ground receiver with quad-antenna diversity (2x directional, 2x omnidirectional) for maximum signal stability.
  • H.265 Video Encoding: Advanced compression reduces bandwidth while maintaining high image quality for longer range.
  • Wide Voltage Input: Supports 6V to 25.2V (2-6S LiPo), allowing flexible power integration without a separate regulator.
  • Betaflight Canvas OSD: Full integration for displaying flight data, battery voltage, and RSSI directly on the HD video feed.
  • Low-Latency Performance: Average end-to-end delay of just 22ms ensures precise control for racing and acrobatic flying.
  • Onboard 8GB Storage: Built-in DVR for recording flights directly on the air unit.
  • Standardized Mounting: VTX features 25.5x25.5mm M2 mounting hole pattern for easy installation on most micro frames.

Applications

  • 3-inch and 4-inch Micro FPV Racing Drones: The lightweight Nano air unit is perfect for builds where every gram counts.
  • Long-Range HD Exploration Quads: The 4km range and stable digital link make it suitable for mid-range cinematic and exploration platforms.
  • Freestyle and Cinewhoop Builds: Provides crisp, low-latency HD video for acrobatic flying and proximity footage capture.
  • Upgrading Analog FPV Drones: A complete kit to transition an existing analog quad to a digital HD video system.
  • Ground Station Setups: The VRX module with HDMI output is ideal for integration into mobile ground stations or for spectators.

Frequently Asked Questions

What is the input voltage range for the Walksnail Avatar HD Nano air unit?

The Avatar HD Nano air unit supports a wide input range of 6V to 25.2V. This allows it to be powered directly from a 2S LiPo (7.4V nominal) all the way up to a 6S LiPo (25.2V max) without requiring a separate voltage regulator, simplifying wiring in high-voltage builds.

How do I integrate the Walksnail system OSD with my Betaflight flight controller?

The Walksnail system supports Betaflight's Canvas Mode for full OSD integration. Connect the air unit's TX/RX wires to a free UART on your FC. In Betaflight Configurator, enable the 'DisplayPort' feature on that UART. Your flight data (voltage, RSSI, etc.) will then be rendered directly into the HD video stream by the air unit.

What is the maximum transmission range of the Avatar VRX + Nano system?

Under ideal conditions with clear line of sight, the system is capable of a maximum transmission distance of approximately 4 kilometers. This range is achieved through the VRX module's quad-antenna diversity system, which combines signals from two directional and two omnidirectional antennas to maintain a stable link.

Can I use the Avatar VRX module with other digital FPV systems like DJI?

No, the Walksnail Avatar VRX module is proprietary and only compatible with the Walksnail Avatar ecosystem of air units (like the HD Nano). It operates on its specific protocol and frequency band (5.725-5.850GHz) and is not cross-compatible with DJI Digital, HDZero, or analog systems.
