Description

The Walksnail AVATAR HD Nano Kit, developed by CaddxFPV, represents a compact digital HD FPV solution engineered for performance and integration. The system utilizes the H.265 video codec to deliver high-quality 1080p imagery at 60fps with a remarkably low 22ms end-to-end latency, making it suitable for both freestyle and racing applications. The VTX employs a robust dual-antenna design to maintain a stable video link at distances up to 4km, while its single-board construction and 25.5×25.5mm mounting pattern ensure straightforward installation into most micro and nano drone frames.

Power management is critical for reliable operation; the system accepts a wide 6-25.2V input, compatible with 2S to 6S LiPo batteries. For 6S setups, installing a capacitor (recommended 50V/47uF or higher) on the battery input is essential to suppress voltage ripple and protect the VTX. The kit includes a 170° field-of-view camera with a 2.1mm F2.0 lens, providing a broad, immersive perspective with good low-light performance down to 0.001 Lux.

Key Features

  • Digital HD 1080p/60fps video transmission with H.265 compression for efficient bandwidth use.
  • Dual-antenna MIMO design enhances signal stability and provides a reliable 4km operational range.
  • Ultra-lightweight VTX design at 16g minimizes impact on drone flight performance and balance.
  • Integrated 8GB flash memory enables direct onboard DVR recording of flight footage in 1080p or 720p.
  • Full-featured Canvas Mode OSD integrates seamlessly with Betaflight, INAV, and ArduPilot for real-time data overlay.
  • Wide 6-25.2V input voltage range supports 2S, 3S, 4S, and 6S LiPo battery configurations with proper filtering.
  • Compact 14x14x17mm camera module with a 170° FOV lens offers an expansive view for precise piloting.

Applications

  • Ultra-lightweight 3-inch and 4-inch long-range digital HD FPV drone builds.
  • High-performance 5-inch FPV racing and freestyle drones requiring low-latency HD video.
  • Compact CineWhoop and micro drone platforms where space and weight are critical constraints.
  • DIY FPV drone projects integrating with Betaflight, INAV, or ArduPilot flight controllers for full OSD functionality.

Frequently Asked Questions

What is the input voltage range for the Walksnail AVATAR HD Nano VTX, and are there any special requirements for 6S use?

The VTX accepts a wide input range of 6-25.2V, making it compatible with 2S, 3S, 4S, and 6S LiPo batteries. For 6S operation, it is critical to install a capacitor on the main battery input leads. A low-ESR capacitor rated at 50V/47uF or higher is recommended to suppress voltage ripple, which can exceed 35V and risk damaging the VTX.

Does the Walksnail system support full Betaflight OSD customization?

Yes, the system features 'Canvas Mode,' which provides full integration with Betaflight, INAV, and ArduPilot flight controllers. This allows pilots to view and customize all standard OSD elements—such as battery voltage, RSSI, flight mode, and artificial horizon—directly through their transmitter, without needing extra hardware.

What is the mounting pattern and weight of the VTX unit?

The VTX board uses a standard 25.5x25.5mm mounting hole pattern, compatible with many micro and standard-sized flight controller stacks. The VTX itself is exceptionally lightweight, weighing only 16 grams, which helps minimize the impact on your drone's overall flight performance and center of gravity.

Can the onboard DVR record video while I am flying with the goggles?

Yes, the VTX includes 8GB of built-in storage that can simultaneously record your flight footage in 1080p or 720p resolution while you are piloting. This recording happens directly on the air unit, so it is unaffected by any potential interference or breakup in the video link to your goggles.
