Flagship Power. Intelligent Control. Absolute Reliability.

The KingTech K-320G4+ stands as the flagship powerhouse of the G4+ turbine series, delivering a commanding 32 kg (70.5 lb) of thrust. Designed for large-scale RC jet aircraft and professional applications, it blends raw performance with intelligent electronic integration and refined engineering.

Built on KingTech’s advanced G4+ platform, the K-320G4+ features full SBus-compatible telemetry, enabling seamless ECU communication for real-time data tracking and control. Every operational parameter—including RPM, EGT, fuel flow, runtime, and performance logs—is automatically stored and accessible for detailed analysis.

The compact DRM (Data Relay Module) consolidates power, data, and signal management into a single lightweight hub, dramatically reducing wiring complexity. A KP1200BL digital SBus brushless fuel pump ensures consistent fuel flow at all RPM ranges, while the brushless starter motor and integrated FOD screen guarantee reliable starts and long service life.

With performance benchmarks including 2173 km/h exhaust speed, 0.53 kg/s mass flow, and 0.163 kg/Nh SFC, the K-320G4+ delivers unmatched efficiency and thrust-to-weight performance within its class.
