Warfare has changed. semperfly puts you in control of the most lethal FPV platforms — fly realistic missions across adversarial terrain, build and tune your multirotors and fixed-wings, and master the physics that separate a good pilot from a great one.
semperfly runs a full SITL physics engine — your flight controller operates in software at its native loop rate, the same gyro cycles and PID calculations as the real firmware.
Most sims let you tweak a slider. semperfly lets you build the aircraft — frame geometry, motor KV, prop pitch, ESC protocol, FC firmware parameters. Every component affects how it flies.
Environments derived from real geodata. Terrain topology generates localised wind and turbulence. Structures create authentic RF occlusion and signal attenuation — not simulated, modelled.
RC transmitter via USB, dedicated flight sticks, standard gamepads — plug in and fly. No proprietary adapters, no driver headaches. Full axis mapping, full control.
Two completely different flight models — multirotor FPV and fixed-wing aircraft — each with their own physics, handling feel, and mission types. One sim, two disciplines.
Structured objectives, dynamic conditions, consequences. Not a sandbox, not a racing game — a sim with something at stake every flight. Build custom scenarios via Workshop.
LAN PvP and co-op. Fly missions together or compete head-to-head. Settle arguments about whose tune is actually better.
The only serious drone sim optimised for handheld. Take it to the field, fly the course before you arm the real one, or just play on the couch. Full experience, no compromises.
Full SITL flight controller physics. Real geodata terrain. Authentic RF signal behaviour. Build your aircraft. Fly your tune. Master the gap between sim and field.
