KingTech K-86G4+ Turbine Engine – 8.6kg Thrust with SBus & Digital Brushless Fuel System

The KingTech K-86G4+ is a powerhouse in the G4+ turbine series, offering 8.6kg (18.95 lb) of thrust in a compact, precision-engineered form. Built with SBus data transmission, this engine seamlessly integrates with the ECU, storing vital data like total runtime, EGT, and RPM directly into the engine system for improved monitoring and maintenance.

This turbine includes a digital SBus brushless pump (KP300BL), a compact Data Relay Module (DRM) for power and signal transmission, and a reliable brushless starter motor for consistent starts and long-term performance. The built-in FOD screen offers added protection during operation, while a micro USB connector supports future app-based connectivity for enhanced user control.

Safety is enhanced with the Ground Support Unit (GSU), which remains active post-flight until engine cool-down is complete—even after the receiver is powered off. Designed for serious RC jet pilots, the K-86G4+ delivers exceptional thrust, intelligent system integration, and dependable durability.
