First Designed FPV Drone
Initial Design
The objective was the architecture and fabrication of a custom quadcopter chassis using fused deposition modeling (FDM). The design utilized PLA (Polylactic Acid) as the primary structural material, housing salvaged logic and propulsion systems from a baseline 2S unit.
Performance Analysis
The structural integrity of the PLA chassis proved inadequate for high-dynamic flight. The material's low tensile strength and inherent flexibility resulted in significant arm oscillation and resonant vibration during motor load. While the system achieved basic lift-off, stable freestyle maneuvers were precluded by the frame's lack of rigidity.
Lessons Learned
Polylactic acid is fundamentally unsuitable for high-performance multirotor chassis. This project confirmed that aeronautical structural components require high-modulus materials, such as carbon fiber composites, to minimize elastic deformation under torque. This data set informed the immediate transition to carbon-fiber-based 3-inch and 5-inch platforms.
