Introducing a cost-effective flight controller PCB designed for budget-conscious drone enthusiasts and educators: powered by the STM32F405RGT6, this board integrates the MPU6050 IMU and BMP280 barometer for stable flight in basic quadcopters and fixed-wing UAVs, offering a reliable, easy-to-integrate solution perfect for learning and experimentation, with open-source compatibility and simplified design.

The Quadcopter Y1101 is a 3D SolidWorks–modeled, high-aerodynamic-resistance racing drone designed for precision, speed, and stability. This project merges simulation-driven design with hands-on fabrication, using 6-inch NACA-M18 propeller blades to maximize lift efficiency and maintain stability at high flight velocities. However, the blade design is fully parametric and customizable, meaning the propeller geometry can be modified or redesigned based on the research methodology being pursued. This allows engineers and researchers to explore performance variations across different airfoil profiles, pitch angles, and chord lengths, enabling targeted optimization for speed, stability, and flight precision in both racing and research applications. The Y1101 was created as a 3D-printable prototype platform for testing aerodynamic performance and control algorithms, bridging the gap between simulation-based design and real-world racing drone prototyping.
