JZ ET4 Four Drop Kit for DJI Matrice 350 RTK and Matrice 400

The JZ ET4 Four Drop Kit is a professional aerial payload release system designed to expand the delivery capabilities of compatible DJI enterprise drones. Featuring four independent release positions, the ET4 enables operators to transport and deploy multiple payloads during a single flight, making it a practical solution for emergency response, search and rescue, field logistics, and specialized industrial operations.

Integrated with DJI Pilot 2, the ET4 supports individual payload release, flexible release sequencing, and one-click simultaneous deployment. Its automatic mounting-position detection helps operators monitor the status of each attachment before deployment, while the built-in laser-assisted aiming function supports more accurate payload placement.

Designed with a compact, lightweight housing and a quick-release mounting system, the JZ ET4 helps streamline aerial delivery workflows while minimizing additional equipment weight.

Key Features

Four Independent Payload Release Positions

The ET4 features four separate mounting positions, allowing operators to carry multiple items and release them independently according to mission requirements. Each position can be activated individually, or all mounted payloads can be released simultaneously with a single command.

Flexible Release Sequencing

Operators can select the release order to suit the delivery mission. This flexibility supports point-to-point delivery, allowing multiple payloads to be deployed at different locations during one flight without returning to the ground after every release.

DJI Pilot 2 Integration

The ET4 integrates with DJI Pilot 2 for convenient operation. Operators can monitor mounting-position status and control payload releases through the supported aircraft interface, helping simplify deployment and reduce the need for additional control equipment.

Automatic Mounting Detection

The system automatically identifies the four mounting positions and displays their status in DJI Pilot 2. This feature helps operators verify payload attachment and prepare the system before takeoff.

Laser-Assisted Aiming

The built-in auxiliary laser helps operators identify the intended drop zone and improve visual alignment during payload deployment. Actual placement accuracy depends on flight conditions, altitude, wind, payload characteristics, and operator technique.

Lightweight and Compact Design

With a body measuring approximately 58 × 58 × 58 mm and a weight of approximately 200 g, the ET4 is designed to add minimal equipment weight to the aircraft. Its compact form supports practical installation and transport.

Quick-Release Installation

The ET4 uses a compatible JZ T-Port interface and quick-release mounting arrangement for supported aircraft configurations. This design helps streamline installation and removal when preparing the drone for different operational tasks.

Applications

Search and Rescue

Deliver essential supplies, communication equipment, and other compatible emergency items to locations that are difficult or dangerous for ground personnel to access.

Emergency Response and Disaster Relief

Support rapid delivery of small emergency supplies to isolated areas affected by flooding, severe weather, or other disasters.

Remote Supply Delivery

Transport and release multiple small packages at designated locations, helping reduce repeated flight cycles during remote operations.

Industrial and Utility Operations

Deploy suitable tools, lightweight components, ropes, or other approved payloads for specialized fieldwork where conventional access is limited.

Public Safety and Field Operations

Support authorized aerial delivery tasks that require multiple release points and flexible deployment sequences.
