Sounds thrilling, but a clean architecture is the best guard against a DIY catastrophe. Start with a central power bus that feeds every module, then add redundant microcontrollers so a single fault can’t bring the whole thing down. Keep each propulsion pod, sensor package, and payload unit as a plug‑and‑play block with standard connectors and quick‑release mounts. Test each block in isolation before integrating, and include a hard‑wired safety cut‑off that wins over any software hiccup. Keep the wiring neat, document every pin, and remember that a single point of failure is the most efficient way to blow up a prototype.

Sounds like you’ve got a solid safety net, but don’t forget the little things—keep the wiring shielded, label every connector, and test the reset button under load before the first flight. A buffer battery is great, just make sure it’s balanced with the main rail and that its discharge curve won’t upset your power budget. With a good test harness and a tidy log of every tweak, you’ll catch any hiccups before they become a launch‑day headline. Good luck, and let’s hope the drone stays on the runway and not in the smoke cloud.
