The FWH-750 is a 700kg-class large coaxial twin-rotor helicopter. This model adopts a coaxial twin-rotor design with compact structure and large payload ratio. It uses a plateau-pressurized aviation engine, solving the problem of excessive power loss of the engine during high-altitude flight, with a service ceiling reaching 6500 meters.The FWH-750 flight control system adopts an intelligent robust control algorithm, capable of handling gusts, high and low temperatures, load changes, and center-of-gravity shifts, enabling stable flight in complex environments.
