Overview
CADDXFPV Walksnail Avatar GT VTX Kit is an FPV VTX kit built for long-range digital transmission. The kit integrates the Avatar GT video transmitter, dual antennas, and the Avatar HD Pro Camera to deliver up to 2W (within local legal limits), 1080p recording, and high-frame-rate low-latency FPV.
Key Features
Long-range, high-power VTX
Up to 2W output (subject to regional regulations) for extended signal transmission distance.
Wide input voltage
11.1V-25.2V power range simplifies installation across diverse airframes.
Dual-antenna architecture
Two IPEX antennas provide stronger, more stable links across the band.
Top-mounted heatsink and active cooling
Thermal design maintains performance during extended operation.
Integrated DVR with Micro SD
Onboard recording at 1080p or 720p to Micro SD cards up to 256GB.
High frame starlight camera
Avatar HD Pro Camera uses a 1/1.8-inch Sony Starvis II sensor for excellent night imaging; supports 1080P/100fps and 720P/120fps.
Low-latency digital FPV
Average delay 22ms with simultaneous support for high and standard frame rates.
Improved GPS interference resistance
Enhanced design for more stable flight links in challenging environments.
Internal ceramic antenna (low-power mode)
Optimizes performance while reducing heat and consumption when low-power is enabled.
Compatibility
Compatible with Moonlight Camera (DVR 4K). Canvas-mode OSD with major FC firmware.

Connection diagram for CADDXFPV Walksnail Avatar GT VTX. Output 5V for fan only; GND, Uart RX, Uart TX (spare pads). Input voltage 11.1V–25.2V; GND, Uart RX connects to FC TX, Uart TX connects to FC RX. Power consumption: 12V@1.5A — ensure power supply can handle this. VTX generates significant heat during operation; maintain proper airflow for cooling. Wires are color-coded: red for power, black for ground, white and gray for UART signals.
