About

About RadioMaster

RadioMaster is the operating brand of Hongkong Maylink Tech Co., Limited, with product design and manufacturing centred at its Shenzhen headquarters and factory. The company sells transmitters, receivers, modules, antennas and accessories globally, and works with open-source communities including EdgeTX. Its official terms restrict products from military, paramilitary and defence use.

Korthos tracks RadioMaster because command and telemetry links are a repeatable hardware layer for civilian drones and other remotely operated machines. The company is not an autonomy developer: its radios carry operator commands and telemetry while flight controllers and onboard software execute vehicle behaviour. Existing supply evidence links RadioMaster equipment to named civilian and commercial platforms. Sales by robotics application, installed-base size and customer concentration are not publicly disclosed.
