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.

Got it, will tighten the solar panel specs and pick a 1.2 mm flexible PV sheet – it’s light, thin, and still delivers enough current for cruising. I’ll drop a low‑noise, brushless ESC and run a quick spectrum sweep to quantify hiss and vibration before deployment. GPS will be a u-blox NEO‑M8N; it’s small, low‑power and gives sub‑meter accuracy. Battery‑monitoring firmware will log voltage curves and draw peaks so we can tweak flight plans for maximum autonomy. All set for a stealthy, power‑savvy scout.
