TH1 drop system for DJI Mavic 3 Enterprise series

TH1 Drop System for the DJI Mavic 3 Enterprise Series

The Chengzhi TH1 is a lightweight, dual-stage drop system designed specifically for the DJI Mavic 3 Enterprise series. It allows you to release payloads quickly, smoothly, and with excellent control, using the drone’s downward light as the trigger signal. With its compact design, easy installation, and impressive lifting capacity, it’s a great add-on for hobbyists who need a practical solution for technical tasks, transport missions, or precision payload delivery in hard-to-reach areas.

High Payload Capacity in a Lightweight Design

Weighing only around 56 g, the TH1 still offers impressive carrying capability. It can handle payloads up to 500 g on a single hook, or up to 600 g when using two hooks. That makes it ideal for delivering small emergency supplies, bottled water, lightweight tools, or technical accessories where accuracy and fast deployment matter most. The module can also be used together with a towing line for added versatility.

• Ultra-light design: approx. 56 g
• Up to 500 g payload on a single hook
• Up to 600 g total payload with two hooks
• Suitable for small supply drops and technical hobby applications

Powered Directly via USB-C

The TH1 is powered through USB-C directly from the drone’s battery, so there’s no need for extra batteries or separate power sources. This helps reduce overall weight, simplifies operation, and lowers the risk of failure. The system is fully compatible with the DJI Mavic 3 Enterprise series and does not require invasive modifications to the drone. Its clever design also helps ensure precise payload delivery and release even in the event of power loss, giving the operator greater confidence during use.

• USB-C power supply from the drone battery
• No extra batteries required
• Reduced weight and simplified setup
• Reliable operation and improved drop control

Simple and Effective Control

The device is activated by a sensor that responds to the drone’s downward light. This means the TH1 works within the same operating range as the UAV control system, without requiring additional wireless modules or extra cabling. The result is a clean, practical setup that is easy to use and convenient in the field.

• Triggered by the drone’s downward light
• No additional control modules needed
• No unnecessary wires or complicated setup
• Convenient operation across the drone’s full control range

Compact, Durable, and Easy to Install

Thanks to its compact size and low weight, the TH1 has minimal impact on the drone’s aerodynamics and flight time. It is made from durable, high-quality materials for long-lasting performance and resistance to damage. Installation and removal are quick and hassle-free, helping reduce preparation time and improve operational efficiency before every flight.

• Compact form factor
• Durable construction made from quality materials
• Fast installation and removal
• Minimal effect on flight performance
