📦 Lightweight, High-Capacity Drop Kit: The TH4 V2 Drop Kit is a professional drop system designed for the DJI M300, M350, and M400 platforms. Weighing only 310g, it supports up to 4 simultaneous drops and a single-drop load of up to 2.38kg, featuring a quick-mount design with seamless DJI Pilot integration.
Product Overview
The TH4 V2 Drop Kit is a compact, powerful, and intelligent drop kit that expands the mission capabilities of DJI’s enterprise drones. It is engineered for rapid deployment and precise payload delivery in applications such as emergency supply delivery, agricultural sampling, and search and rescue. The system’s strength lies in its combination of a high strength-to-weight ratio (310g unit carrying up to 2.38kg), its quick-mount interface (DJI SkyPort V2.0), and its deep integration with the DJI Pilot app, which eliminates the need for third-party controllers. Featuring a max height of 97mm and a max diameter of 78mm (including the conversion ring cover), it is highly portable without sacrificing performance.
For emergency response and logistics teams, this system serves as a robust 4-point aerial payload drop system, capable of carrying multiple supplies to different locations in a single flight. As a precise heavy-lift drone drop kit, it supports a substantial single-hook capacity of up to 2.38kg, making it ideal for medical or critical supply delivery. Its seamless integration with the app classifies it as an app-controlled drone payload release, simplifying operations for pilots. Furthermore, its reliable mechanism qualifies it as a dependable emergency drone supply thrower, ensuring safe and accurate deliveries in high-stakes, time-critical missions.
Key Features
- Multi-Drop Capability: Supports up to 4 payloads hanging simultaneously and can be dropped sequentially. The digital imaging camera displays the loading position in real-time, ensuring accurate placement.
- High Strength-to-Weight Ratio: Weighing only 310 ± 5g, it is exceptionally lightweight, minimizing impact on flight performance. Despite its small size, it supports a single throw up to 2.38kg (Actual load depends on the drone and gimbal payload capacity).
- Fast Mount/Dismount & Easy Control: Utilizes the DJI SkyPort V2.0 interface for quick and secure attachment. No need for a third-party controller. The DJI Pilot / CZI Assistant floating window (CZI Assistant supports M350) automatically recognizes the thrower and displays a live message pop-up tips window, simplifying operation.
- Reliable and Safe: Features a simple utility design with multiple malfunction-proof mechanisms to prevent miss-dropping, ensuring safe and accurate payload delivery. Please ensure the payload is fully suspended before pressing the drop button and keep hands away from the mechanism.
- Versatile Mounting & Payload Capacities:
- Using a Single Gimbal Mount: M300 RTK max ≤ 620g; M350 RTK max ≤ 650g.
- Using Strapped/Integrated Mount (Binding the gimbal top frame and bottom frame): M300 RTK max ≤ 2270g; M350 RTK max ≤ 2300g.
