Tianxun F20 VTOL Fixed-Wing UAV by Treasure Marine

The Tianxun F20 VTOL Fixed-Wing UAV from Treasure Marine is a long-range industrial drone that combines vertical takeoff and landing with the efficiency of fixed-wing flight. With a maximum takeoff weight of 25kg and a payload capacity of 4kg, it carries cameras, thermal imagers, and other mission equipment over large areas without needing a runway, catapult, or parachute recovery.

The aircraft uses a hybrid configuration. Lift rotors raise it straight up from small clearings, rooftops, or vehicle beds, then the fixed wings take over for cruise flight once it reaches a safe altitude. This approach cuts power use during forward flight, which allows longer endurance and greater coverage than multirotor drones of a similar size. At the end of the mission, the aircraft transitions back to multirotor mode and lands vertically at a precise point.

The airframe is made from lightweight composite materials that balance strength with low weight. The aerodynamic fuselage and wing shape reduce drag and keep the aircraft stable in crosswinds, while the modular structure allows the wings, tail, and body to be separated for transport. Teams can pack the system into a compact case and move it between sites in a standard vehicle.

Flight control relies on a high-precision autopilot with redundant sensors and satellite navigation. It supports automatic takeoff, route following, mode transition, return to home, and landing, so operators can focus on mission data instead of manual piloting. Safety functions such as low battery response and signal loss protection add extra confidence during long flights.

Surveillance Capability and Wholesale Supply from Treasure Marine

The F20 is well suited to long-range surveillance and monitoring. A stable data link provides live video and telemetry to the ground station across extended distances, giving operators a clear view of the mission area in real time. The payload bay accepts electro-optical cameras, infrared sensors, and mapping equipment, and mounting options can be adjusted to match the task.

Typical applications include border and perimeter patrol, power line inspection, pipeline monitoring, forestry and wildfire observation, aerial surveying, and emergency response. Because one flight can cover a wide area, teams complete more work in less time and reduce the number of takeoffs and battery changes.

As a factory-direct product, the Tianxun F20 is available from Treasure Marine for wholesale and OEM orders. Buyers can request custom branding, payload configurations, battery options, and packaging. Each aircraft is tested before shipment to confirm stable flight performance across large orders.
