Overview
The XF C-20D Vertical 2-Axis Gimbal is a compact stabilization platform for small cameras and FPV image-transmission kits. It supports DJI O4 Pro, DJI O4, DJI O3, Walksnail Avatar, Walksnail Moonlight, and 19 mm wide analog cameras. A 2-axis mechanical stabilization structure and high‑torque motors deliver strong resistance to vibration and high-speed airflow, while Headtracker support enables immersive first-person control.
