Dual-stage payload release for better control

The TH2 uses two independent release points, allowing you to drop payloads one after another with improved precision. In single-hook mode, the system supports loads of up to 500 g. In dual-hook mode, each hook can carry up to 300 g. This makes it a great choice for transporting lightweight items such as ropes, tools, or compact emergency supplies, especially when accuracy matters.

Simple light-based control

The module is equipped with a photoresistor that responds to the drone’s bottom light. The first drop is triggered when the light is turned on, and the second drop activates when the light is switched on again. This smart solution keeps operation simple, reduces setup time, and eliminates the need for additional cables or external control units.

Lightweight design made for DJI Matrice 4

Engineered for full compatibility with DJI Matrice 4 series drones, the TH2 features a slim and lightweight design that has minimal impact on flight stability and aerodynamics. Thanks to its quick-release mounting system, installing the accessory and getting ready for takeoff is fast and convenient.

Durable construction for outdoor use

The housing is made of PC+ABS and aluminum alloy for a solid balance of low weight and durability. The system can operate in temperatures from -20°C to 50°C and handle humidity levels of up to 95%, making it suitable for a wide range of outdoor environments and hobby drone applications.
