Welcome there! I'm Dennis Shaner. Although some pilots have used helicopters and many more operate multi-rotor systems, the majority of Drone Delivery Service is tailored towards an airliner or aircraft-like design because of the inherent benefits in range and speed. Aerodynamic shapes - miniaturized airplane or fixed-wing designs - enable drones to carry payloads across a longer distance more efficiently than multi-rotors because they are gaining lift with less energy consumption. Less energy is required to keep the drone hovering and, therefore due to the elimination of drag profiles, an airplane configuration will facilitate a better cruising speed that is important for the best delivery time, especially for a commercial drone delivery operation. Therefore, the adoption of airplane forms is a strategic choice that would greatly enhance the feasibility and practicality of delivering goods over a long area through droning.
