Overview
Walksnail Pro Kit with GM3 is built around the CADDXFPV GM Series gimbal concept (support head tracking when paired with Avatar Goggles). The GM gimbal series is designed for FPV cameras to deliver stable, smooth video, with head tracking support for a more immersive FPV experience.
Key Features
- CADDXFPV GM Series: support head tracking when paired with Avatar Goggles
- Mechanical stabilization to reduce camera shake (stabilized vs. unstabilized effect)
- Gimbal mode and sensitivity management through the Avatar goggles menu or via PWM controls
- Control modes: PWM / UART
- Includes a coaxial cable connection to the VTX for head tracking functionality
- Designed for broad FPV platform use: FPV drone, RC FPV wing, RC car
- Avatar goggles menu example (as displayed): Settings > Camera with Scene, EV, Saturation, Sharpness, WB, Rotate, Ratio
Compatibility Notes
- Designed to work with Avatar HD goggles for head tracking control.
- VTX compatibility: not compatible with V1 VTX, Mini 1s, Nano V3, and GT VTX; compatible only with V2 VTX, V2 VTX Dual, and Moonlight VTX.
- Camera compatibility (GM series): 19mm FPV camera.

Details

CADDXFPV GM Series gimbals add mechanical stabilization and head tracking support when paired with Avatar HD Goggles.


Mechanical stabilization helps smooth out vibrations for cleaner FPV video compared with an unstabilized camera.

Gimbal behavior and camera settings can be managed directly through the Avatar goggles menu or via PWM controls.


The kit wiring includes a coax-style connection between the gimbal and VTX to enable head tracking functionality.
