High Thrust. Intelligent Control. Proven Reliability.

The KingTech K-142G4+ is a premium high-thrust turbine engine engineered for serious RC jet pilots who demand uncompromising power, precision, and integration. Delivering 14 kg (30.86 lb) of thrust, it’s built for advanced jets and large-scale models requiring powerful propulsion and dependable performance.

Part of the KingTech G4+ series, the K-142G4+ incorporates SBus digital data transmission, providing seamless engine-to-ECU integration and real-time telemetry for RPM, EGT, and total runtime. The digital SBus brushless fuel pump ensures stable and precise fuel delivery, while the lightweight Data Relay Module (DRM) manages all signal, power, and telemetry connections, minimising wiring and installation time.

The brushless starter motor guarantees consistent ignition, and an integrated FOD screen safeguards the turbine from debris. The micro USB port enables future wireless app connectivity, making this turbine future-ready.

After flight, the Ground Support Unit (GSU) remains active during cool-down even when the receiver is switched off — protecting components, extending lifespan, and ensuring a safe shutdown every time.
