ZIYAN Technology has successfully completed a real-world flight test of its Grey Whale G1 unmanned helicopter, verifying the platform's long-range transport capability using an onboard winch system under operational conditions.
In the test, the Grey Whale G1 carried a 10 kg payload via winch-based lifting and achieved a verified flight distance of 33 kilometers. All key performance parameters, including payload stability, flight endurance, and system reliability, were recorded throughout the mission, providing measurable validation of the aircraft's transport performance.

The winch-based configuration enables flexible payload handling without the need for landing, making the Grey Whale G1 particularly suitable for logistics resupply, emergency delivery, and complex transport missions in constrained or inaccessible environments. Stable flight performance was maintained throughout the mission despite the external load.
This successful test reflects ZIYAN's continued focus on field-verified performance, ensuring that system capabilities are demonstrated through real operational scenarios rather than theoretical specifications. The Grey Whale G1 is designed to deliver reliable payload endurance where it matters most—in the field.
