#SmallRig mounting plate for DJI RS 2 / RS 3 / RS 3 Pro 3249

The SmallRig Mounting Plate for DJI RS 2 / RS 3 / RS 3 Pro (Model 3249) is a specialized, horizontally adjustable replacement baseplate designed to expand the camera-carrying capacity of professional DJI handheld stabilizers.

The primary engineering purpose of this plate is to solve a common mechanical issue: standard gimbal baseplates are too narrow to properly balance wide-body camera configurations. The 3249 baseplate replaces the gimbal’s native vertical tilt-axis arm mount, allowing filmmakers to manually shift wide cinema cameras horizontally away from the motorized arm to achieve a flawless balance.

Core Engineering and Operational Features

• Horizontally Stretchable Base Extension: The plate features a manual sliding rail core that can be extended sideways via a secure flip-lock lever. By expanding the clearance distance between the gimbal’s vertical tilt motor and the camera body, it allows the stabilizer to balance wide, heavy configurations—such as a fully caged Blackmagic Pocket Cinema Camera 6K Pro or 6K G2—without hitting the motor arm.

• Manfrotto 501 Quick-Release Architecture: The upper receiver channel matches standard Manfrotto specifications. It accepts the original DJI Manfrotto-style quick-release plates or SmallRig aftermarket equivalents (such as SKUs 3061, 3158, or 3031B), enabling fast transitions from a fluid-head video tripod straight onto the gimbal without unbolting the camera.

• Integrated Anti-Release Safety Mechanism: To eliminate the catastrophic risk of a camera sliding out of the docking groove on a busy set, the plate incorporates a spring-loaded, anti-drop safety pin block alongside its primary quick-locking clamp lever.

• Native RavenEye Ecosystem Support: The bottom chassis of the 3249 baseplate features a dedicated slide-in mounting slot designed to hold the official DJI RavenEye Image Transmission System. This keeps the video transmitter balanced centrally beneath the lens axis, freeing up space on the camera's top hot shoe.

• Accessory Cheese-Plate Array: The outer edges of the aluminum plate feature multiple 1/4"-20 threaded holes. These points allow camera assistants to mount counterweights, universal power bank holders (such as SmallRig SKUs 2336 or 2790), or mini V-mount battery plates (SKU 2987) directly to the baseplate assembly to power the camera during extended tracking shots.

💡 Operational Gimbal Rigging Tips for the 3249 Plate

The Left-Heavy Balance Principle: Wide cameras like the BMPCC 6K Pro are naturally left-heavy because of their wide lens mount placement and left-side audio/video ports. When mounting this assembly onto your DJI stabilizer, loosen the 3249 plate's integrated flip-lock and slide the horizontal extension tray outward to the left before you start adjusting the gimbal's built-in axis arms. Shifting the camera base away from the tilt motor first creates the necessary physical clearance, preventing the camera cage from scratching against the gimbal's aluminum arm during steep vertical tilts or rapid roll transitions.

• Managing Heavy Lens Face Drops: If you pair a wide camera body with a heavy, long cinema zoom lens, the camera will naturally dive forward, often exceeding the length adjustment limit of standard quick-release plates. To fix this, pair the 3249 baseplate with the SmallRig Extended Quick Release Plate (3031B). The extended plate slides smoothly into the 3249's Manfrotto receiver, giving you an extra 1.6 inches (4cm) of forward-and-backward travel to balance front-heavy lenses without needing bulky counterweights.

• Securing Heavy Payloads Against Motor Jitter: When balancing high-payload camera configurations near the gimbal's maximum weight rating, any microscopic flex or loose connection in your baseplate will trigger micro-vibrations. This forces the DJI high-torque brushless motors to overcompensate, causing audible humming, lens jitter, or temporary motor shutdown. To avoid this, always make sure the 3249's main clamp lock and its side horizontal extension flip-lever are pushed completely flush into their locked positions before executing the gimbal's automated electronic "Auto Tune" calibration sequence.
