SF-X4-F7000 Hybrid UAV
Long-endurance heavy-lift hybrid quadcopter
Model: SF-X4-F7000
Overview
Hybrid-electric quadcopter with an F7000 integrated genset, 57 kg MTOW and up to 20 kg mission payload. Empty airframe with full fuel hovers about 120 min—suited to long-endurance inspection, lighting and industrial missions.
Highlights
- 57 kg MTOW, up to 20 kg mission payload
- F7000 liquid-cooled hybrid: 6500 W continuous / 7000 W peak
- ~120 min hover endurance (empty + full fuel)
- RTK accuracy ±0.1 m / ±0.2 m
- Wind: sustained Beaufort 6 / gust 7
Key Features
- X-layout quadcopter with carbon-composite + aerospace 6061 aluminum structure, fold-latch arms and fixed heavy-duty damped landing gear.
- F7000 integrated starter-generator with closed-loop liquid cooling: 6500 W continuous / 7000 W peak; 95# gasoline + FD-grade 2-stroke oil (40:1).
- Hover fuel burn ~9.0 L/h (sea level, 25°C, rated full load); standard 12 L tank; one-button electric start.
- Endurance references: empty + full fuel ~120 min; 15 kg + 8–9 L ~1 h; 10 kg + 16 L ~2 h; 10 kg + 12 L ~1 h with residual fuel.
- Triple-redundant industrial multirotor FC (Boying Navigation) with waypoint, auto-RTH, altitude/position hold and autonomous modes.
- GPS + BDS + GLONASS with u-blox ZED-F9P; SIYI A8 mini gimbal + MK15 digital video/GCS (LOS ~5–10 km, extendable to 30 km).
- IP54 airframe; hybrid main power + 14S backup battery; short operation in light rain allowed.
