Lowental Hybrid’s GH-04 aerial generator is a twin-cylinder boxer power system engineered for multi-rotor drones up to 35 kg MTOW. Delivering up to 4.0 kW of output, it combines robust dual-cylinder reliability with advanced electronic fuel injection for consistent performance and optimized efficiency. Designed for demanding missions requiring longer flight times and heavier payloads, GH-04 offers flexible integration and a fast setup process across various multi-rotor platforms.
The system features an air-cooled, two-stroke boxer engine with an automatic built-in starter generator. It runs on premixed gasoline or heavy fuel with 4% two-stroke oil. With in-flight start/stop capability, operators can transition seamlessly to silent electric flight when required. GH-04 supports multiple telemetry and communication protocols, including CAN bus, MAVLink, RS-485, Ethernet, and UART, ensuring full system compatibility and reliable data connectivity.
