Built a custom quadcopter by selecting and integrating propulsion, avionics, power electronics, and structural hardware. Designed the electrical architecture, assembled and soldered the wiring harness, integrated the flight controller and ESCs, and verified the system through electrical testing.
Thrust-to-weight ratio

Flight hardware architecture
01Problem
I wanted to understand how a multirotor drone actually works at the component level instead of treating the drone as a black box.
Broke the system down into propulsion, power, avionics, and structural subsystems to understand how each one affects flight performance.
Focused on how motor, propeller, and battery choices constrain flight time and speed.
02Approach
Designed the quadcopter around a complete hardware stack, selecting and integrating the propulsion, power electronics, avionics, and frame as one system.
Sized the motors, props, ESCs, and LiPo battery around vehicle mass, thrust requirements, voltage, and flight time feasibility.
Integrated the flight controller, power distribution, signal wiring, and structural hardware into a complete quadcopter architecture.
03Result
Completed system integration and successfully flew the custom quadcopter through multiple flight tests.
Soldered and wired the power and control paths, then integrated the ESCs, motors, battery, receiver, and flight controller.
Completed multiple flight tests and tuned the flight controller to enable autonomous takeoff and landing modes.
