Purpose-built maps designed for readable lines, honest scale, and repeatable practice sessions.
Dialed-in controls
Responsive input with headroom to tune rates and feel so the sim matches your setup.
Smooth on desktop

Free to fly
Completely free — download, plug in a controller, and get in the air.
Flight simulator
Freestyle · Line practice
Practice that carries over to the real thing.
Simulators are only useful when the flying is honest. BostromFPV Sim is built from real flight experience — the goal is muscle memory you can trust when you switch back to a physical quad.
It starts with the flight model and works outward: controls, maps, and performance all tuned so nothing gets in the way of the line you're trying to hit.
