Overview

I designed and built a modular quadcopter intended for GPS-guided missions and straightforward component replacement. The frame combines FDM-printed plates, clamps, and mounts with tube arms.

I integrated the flight controller, GPS, and power distribution within the frame, then configured PX4 and carried out flight tuning.

Build and testing notes

Earlier project notes describe tuning for structural resonance; a measured vibration spectrum is not available here.
The available simulation files do not establish physical performance or structural test results.
