5-inch FPV freestyle quad

Not a robot with a camera — a robot whose entire control loop (Betaflight at 8 kHz) is in your hands, with a physics-to-frame ratio no ground robot can match.

Why it matters

Fastest feedback loop of any robot you can build. A tuning change is measurable in the next flight — no simulator round trip.

Where it falls short

Every crash is money. And in most jurisdictions a 5-inch quad needs registration and a spotter — check the rules before you fly.
