Product overview
The Jiangzhizai YT-400 is a UAV payload release attachment intended for carrying and deploying fire-extinguishing munitions. Its compact assembly combines control, power supply and payload attachment within a 155 × 100 × 79mm envelope weighing approximately 645g. Four hooks are supplied as standard, with independent control allowing an operator to select individual attachment points or release all payloads together. Each hook supports up to 6kg, while four hooks working together provide a stated capacity of up to 24kg.
Developed specifically for the DJI M400, the YT-400 uses the aircraft’s original mounting holes and supports installation without drilling or modification. PSDK integration brings operation into DJI Pilot 2 without an additional controller or ground station. It requires a 24–80V supply and has a specified operating temperature of -20°C to 45°C. Airburst operation uses external radar altitude and app settings; the technical specification gives 1–20m, while the feature description gives 3–20m. The fire-extinguishing munition has a safety switch, with its status displayed on the remote controller.
