KingTech K-85G4+ Turbine Engine – 8.5kg Thrust with SBus Integration & Brushless Fuel System

Engineered for elite RC jet pilots, the KingTech K-85G4+ is a high-performance turbine engine that combines raw thrust with smart integration. Delivering 8.5kg (18.74 lb) of power, the K-85G4+ is part of KingTech’s advanced G4 platform, offering SBus data transmission for real-time communication between engine and ECU. Operational data—including total runtime—is stored within the engine, supporting smarter maintenance and diagnostics.

This model includes a digital SBus brushless fuel pump, a compact Data Relay Module (DRM) to manage all signal, power, and data connections, and a brushless starter motor for exceptional durability. A built-in FOD screen provides onboard engine protection, and the micro USB port is designed for upcoming wireless app connectivity.

Safety features include a Ground Support Unit (GSU) that stays active during engine cooldown—even if the receiver is turned off—protecting your equipment after flight. With its reliable build and powerful output, the K-85G4+ is ideal for medium to large-scale RC jet aircraft.
