A 5-inch X-quad built around the locked 16 × 16 mm M3 motor pad, a Pixhawk 6C flight controller and a Raspberry Pi 5 + Hailo-8L perception tray. Every part prints flat-bottom on a Bambu A1 in PLA or PETG with no supports. The 4Quad is the first airframe through the full bench-test sequence and the first to fly on the 3S pack.
