The flight management control system, referred to as the flight control (FC series products), is one of the core components of drones. Its main functions include navigation, control, actuator output, and higher-level mission planning. Currently, the flight control can provide control of multiple models, such as: cross-country drones, multi-rotors, helicopters (single rotor, coaxial twin rotors, tandem twin rotors), vertical take-off fixed wings, cruise missiles, tilt-rotors, etc., and accept customized mission requirements.
