KingTech K-235G4+ Turbine Engine – 23.5kg Thrust | SBus, DRM & KP800BL Pump

The KingTech K-235G4+ is a high-thrust, high-efficiency RC turbine engine engineered for serious performance in large-scale jets. With an output of 23.5kg (51.8 lb) of thrust at peak RPM, it is the most powerful model in the G4+ series, making it ideal for heavy airframes and demanding flight maneuvers.

Powered by KingTech’s advanced G4 ECU system, the K-235G4+ features SBus data transmission for seamless digital integration, allowing live telemetry and internal logging of engine metrics like RPM, run time, and EGT. At the heart of its fuel system is the KP800BL digital SBus brushless pump, delivering reliable, high-volume fuel flow with pinpoint precision.

The Data Relay Module (DRM) streamlines installation by managing all signal, power, and data transfer in one compact, lightweight unit. Additional features include a brushless starter motor for consistent ignition, a built-in FOD screen for added protection, and a micro USB port for future app-based tuning and monitoring.

With a pressure ratio of 3.7:1, mass flow of 0.46 kg/s, and exhaust gas speed of 1839 km/h, the K-235G4+ balances raw thrust with aerodynamic efficiency. Its Ground Support Unit (GSU) continues operation post-flight for cooldown, extending the engine’s service life and ensuring thermal safety.
