Problem Solved High Performance 3.5in FPV Drone

Everyone knows 5‑inch 6S FPV drones dominate the skies, but they have a major downside: they’re loud—very loud—and not everyone appreciates the distinct, high‑pitched scream of a 5‑inch 6S FPV drone. So I built a smaller, quieter 4S 3.5‑inch drone with the same capability to carry an action camera, along with a seemingly endless amount of power, allowing me to dominate the skies over my neighborhood without upsetting my neighbors.
