However, multi-rotor aircraft are affected by the fuselage structure and cannot use larger blades to improve efficiency and reduce noise. The market generally has 4 / 6 / 8 rotor drones. A few two-axis tilt-rotor drones also have the disadvantages of large size and poor response. In addition, the two-axis vector drone has a unique shape and is also a blank market.
