High Thrust. High Efficiency. Total Control.

The KingTech K-235G4+ is a high-thrust, high-efficiency turbine engine engineered for serious performance in large-scale RC jets. Delivering an impressive 23.5 kg (51.8 lb) of thrust, it stands as one of the most capable and powerful models in the KingTech G4+ series, built to handle heavy airframes and demanding 3D and precision aerobatic flight profiles.

Powered by KingTech’s advanced G4 ECU system, the K-235G4+ features SBus-compatible telemetry for seamless digital integration, providing real-time data on RPM, EGT, and runtime — all internally logged for in-depth performance tracking and maintenance insight.

The lightweight DRM (Data Relay Module) consolidates all signal, power, and telemetry connections, making installation clean and efficient. A KP800BL digital SBus brushless fuel pump ensures stable, high-volume fuel flow at all throttle settings, while the brushless starter motor guarantees smooth, reliable starts.

A built-in FOD screen protects internal components from debris, and the micro USB interface supports upcoming app-based connectivity for advanced tuning and monitoring.

With a 3.7:1 pressure ratio, 0.46 kg/s mass flow, and 1839 km/h exhaust velocity, the K-235G4+ balances power, response, and aerodynamic efficiency for the highest levels of RC turbine performance.
