The coaxial rotor is one of the most technologically advanced in the world. No more than 10 countries can be produced. The export of coaxial rotor UAVs could affect the national interests of China in the future, the technology will spread and fall into the hands of many hostile countries.
China should now focus on R&D towards tandem-rotor and tiltrotor designs. Even if they are not produced in the near future, China shouldn't lag significantly behind in the potential for any platform capability.
