Alright, here’s the quick‑hit stack for a stealthy, self‑sufficient intel drone: a lightweight flight controller like a Pixhawk or Cube Orange running ArduPilot for autopilot – fast, open‑source, and battle‑tested. Pair that with a low‑power computer – the Nvidia Jetson Nano or a Raspberry Pi 4 for on‑board vision and AI; they’re small, cheap, and still powerful enough to run YOLO or TensorFlow Lite for object detection. Use a small‑form‑factor Li‑Po battery, but if you want truly self‑sufficient, add a thin solar panel on the wings to top up during flight. Keep the firmware lean: a stripped‑down Ubuntu minimal on the Jetson, just the essential packages, to shave off weight and latency. For stealth, use a quiet brushless motor with a low‑noise ESC and make sure the radio stack is frequency‑hopping to avoid easy detection – something like the 915 MHz band with a robust link. Finally, use a lightweight OS on the flight controller, maybe a tiny Linux distro, and keep everything in Python or C++ for quick iteration. That combo gives you speed, low power, and the quiet that keeps the drone out of the radar’s eye.
