Product overview
The HEQ G-Port 3-Axis Gimbal Component provides mechanical camera stabilization for aerial filming and FPV installations. Its pitch, yaw and roll assembly measures 48.5 × 49 × 67.5mm. Weight depends on configuration: the DJI O3 and Caddx version weighs 67g, the DJI O4 Air Unit version 75g, and the DJI O4 Air Unit Pro version 71g. Upright, inverted and other mounting arrangements support integration into quadcopters, VTOL fixed-wing aircraft and RC cars. Camera compatibility depends on the selected version, with DJI, CADDXFPV, Walksnail and RunCam options.
The component package contains one gimbal, four damping balls, one carbon fiber mounting plate, three G-Port cables, six mounting screws and one user manual. It arrives configured in Stabilization Mode for use after installation. Parameter adjustment requires HEQ Ground Control Software on Windows; connect power before attaching a data-capable USB Type-C cable. A dedicated self-centering transmitter channel selects Stabilization Mode at 1000–1400 and FPV Lock-Axis Mode at 1600–2000. A transmitter with a three-position switch is recommended.
The gimbal requires a 12–18V supply, and voltage above 18V may damage its main control board. Mechanical travel spans pitch -135° to +45°, yaw -135° to +135° and roll -45° to +45°. It is not waterproof; purchasing and installing a suitable cover or enclosure is recommended when waterproof protection is required. Control protocols are listed as SBUS, PWM, MAVLink and CRSF, although direct ELRS and CRSF connections are unsupported. An ELRS-to-SBUS conversion module is available separately for connection.
