Product overview
HOBBYWING positions the H13MD as a coaxial propulsion system for industrial heavy-lift UAVs carrying out material lifting, logistics, firefighting and emergency rescue. Its procurement scope is a propulsion assembly for aircraft integration. The listed configurations pair the H13MD with MSC 54x20 or MSC 57x20 carbon non-folding propellers. Their published maximum thrust figures are 110kg and 113kg respectively, while both carry a recommended takeoff loading of 45kg per axis. These figures require confirmation against the selected configuration.
The mechanical arrangement combines the motor and ESC on an aluminum-alloy motor base, using a tube-clamp assembly with four-direction locking. Integration planning should accommodate the published 60mm arm-tube diameter and 2.5mm wall thickness, together with the manufacturer's 3-degree clamp tilt. Assembly weight includes cables and propellers and differs between the two listed propeller configurations. Electrical integration involves a 24S–28S LiPo supply, PWM+CAN throttle signals and the specified propeller mounting pattern. DroneCAN support and named controller ecosystems provide integration starting points, but compatibility should be checked for the selected controller and firmware.
The specification table identifies 13825-37KV motors and H150A-FOC ESCs, with non-folding carbon propellers in both configurations. Folding propellers, alternative tilt adapters, cable changes, motor temperature monitoring and propeller locking appear as options or customization services, so their inclusion requires confirmation. Throttle travel calibration is explicitly unsupported. 180kg takeoff weight, 100kg recommended payload and 20min+ endurance belong to its recommended aircraft configuration, including two 24S 70000mAh batteries. Published load curves are laboratory reference values at 25°C and sea level; the unclear temperature-measurement wording warrants clarification before using those curves for procurement sizing.
