A quadcopter is one of the most versatile unmanned aerial vehicles (UAV) used for a variety of tasks. Quadcopters are symmetrical and use the simplest principle of operation for controlling roll, pitch, yaw, and motion. A DJI F450 quadcopter frame design with optimized geometry is used in this project.All the frame's components were designed using Fusion 360.Based on the results of stress analysis with Fusion 360, the proposed design is validated for its feasibility, and a suitable material for fabrication is selected through comparison with five other materials.In this paper, we investigate the static stress in the quadcopter frame and the modal frequencies in the quadcopter arm.
