KingTech K-320G4+ Turbine Engine – 32kg Thrust | SBus, DRM & KP1200BL Brushless Pump

The KingTech K-320G4+ is the flagship powerhouse of the G4+ turbine series, delivering a commanding 32kg (70.5 lb) of thrust. Designed for the most demanding large-scale RC jet aircraft, this turbine engine blends brute force with precision electronics and intelligent telemetry integration.

Built on KingTech’s advanced G4+ platform, the K-320G4+ features SBus-compatible ECU communication, providing seamless data transmission and control. All operational parameters—including total runtime, RPM, EGT, and performance logs—are internally stored, offering robust flight data tracking.

The external DRM (Data Relay Module) consolidates signal, power, and data lines into one compact and lightweight unit, simplifying setup and improving reliability. The system uses a high-performance KP1200BL digital SBus brushless pump to maintain steady, high-capacity fuel delivery at all RPM ranges.

With a micro USB port built-in for future wireless app compatibility and a brushless starter motor, the engine ensures durable starts and long-term reliability. The integrated FOD screen protects the turbine core from debris during operation. After shutdown, the GSU remains active during cool-down, enhancing safety and component lifespan.

With performance metrics like 2173 km/h exhaust speed, 0.53 kg/s mass flow, and 0.163 kg/Nh SFC, the K-320G4+ offers unmatched efficiency in its class.
