Expanding Drone Capabilities: The RDD Series Payload Release Systems for DJI Platforms

As drones take on more critical roles in industrial and emergency operations, the demand for intelligent, reliable payload delivery systems continues to grow. Whether it’s deploying life-saving supplies or supporting infrastructure tasks, drone-based aerial delivery is transforming how we respond to challenges on the ground.

The RDD Series payload release systems are designed to meet this growing demand with powerful, multi-channel, and mission-ready solutions—fully compatible with DJI enterprise drones such as the M30, M300 RTK, M350 RTK, and FC30.

What Is the RDD Series?

The RDD (Release and Drop Device) Series is a family of DJI Payload SDK-based drop systems tailored for drone-enabled delivery tasks. Each model in the series is engineered for a specific weight class and mission scenario, enabling operators to deploy materials precisely and safely from the air.

From lightweight emergency kits to heavy-duty equipment, the RDD Series supports a wide range of payloads with features such as real-time video feedback, modular design, and multi-point drop control.

RDD-2: Lightweight, Dual-Channel Dropper for DJI M30/M30T

The RDD-2 is a compact, dual-channel payload release module developed specifically for DJI M30 and M30T drones. With a max payload of 2kg per channel, it's well-suited for rapid response scenarios where size and speed matter.

Key Features:

• Dual-channel release with up to 2kg per hook

• Integrated with DJI Pilot2 via PSDK for real-time control

• Compact slanted hook design for minimal drone impact

• Manual release button for quick on-site operations

• Reserved interface for warning light integration

Ideal for: Emergency kits, small-scale supply delivery, and light-duty utility tasks.

RDD-25: Four-Channel Multi-Payload Delivery for DJI M300/M350

Built for DJI M300 and M350 RTK platforms, the RDD-25 expands aerial delivery capabilities with four independent release modules. Each channel can carry up to 2.5kg, for a total payload capacity of 10kg.

Key Features:

• 4 independent release channels

• Sequential drop functionality for multi-point delivery

• Max 2.5kg per module, 10kg total

• Plug-and-play compatibility via DJI PSDK

Ideal for: Power line deployment, fire extinguisher drops, emergency supply delivery, and search & rescue.

RDD-25A: Visualized Precision Drops with Real-Time Video

The RDD-25A adds a visual dimension to the RDD-25 by including a video transmission unit that connects to the drone’s gimbal interface. This enables real-time downward video feed to the operator, allowing visual confirmation of drop zones before release.

Key Features:

• Real-time FPV video transmission via DJI gimbal port

• Drop module connects via Type-C to the video unit

• 4-channel release with sequential or simultaneous control

• Compatible with DJI M300/M350 drones

Ideal for: Tasks requiring visual verification, such as medicine delivery, search coordination, or targeted relief drops.

RDD-120: High-Capacity Delivery for Heavy Payloads

Designed for the DJI FC30 heavy-lift drone, the RDD-120 is a powerful four-channel system built to carry up to 30kg per module—totaling 120kg. This model is ideal for industrial-scale deliveries where weight and stability are crucial.

Key Features:

• 30kg payload per channel, 120kg total

• Four-channel sequential release to maintain flight balance

• Rugged construction for high-load performance

• Designed specifically for the FC30 platform

Ideal for: Fire suppressant delivery, large-scale material transport, power grid equipment drops, and remote infrastructure tasks.

Compatibility & Safety Considerations

While each RDD module supports high payload capacities, users must always ensure the drone’s overall weight limit is not exceeded. The listed capacities refer to the maximum for each release module—not the aircraft’s own maximum load. Always check compatibility and weight limits for your specific DJI platform before deployment.

Enabling the Future of Aerial Delivery

The RDD Series unlocks powerful new capabilities for DJI enterprise drones, transforming them into versatile aerial delivery tools across public safety, energy, and logistics sectors. With modular designs, seamless software integration, and precision control, the RDD-2, RDD-25, RDD-25A, and RDD-120 provide drone operators with scalable solutions for complex missions.

Whether you're delivering life-saving supplies or deploying utility equipment in hard-to-reach areas, the RDD Series delivers performance you can count on—every time.
