K86G4+ Fourth Generation Turbine

The Next Generation of Jet Turbine Technology

The K86G4+ represents the fourth generation of turbine technology, bringing together a cleaner installation, smarter electronics and a new generation of data management in a compact and high-performance package.

The new KT-Bus system significantly simplifies installation by reducing the turbine connection to a single cable through an XT30 connector. The system integrates power, data and signal distribution into one streamlined connection, making installation cleaner and easier while reducing cable clutter inside your model.

The K86G4+ also introduces an integrated FOD screen, brushless starter and ECU mainboard, together with advanced monitoring and control functions designed for modern turbine-powered models.

Smart Connectivity & Data Management

One of the major innovations of the G4 generation is the integrated Data Relay Module (DRM).

Built directly into the turbine, the DRM handles the transmission of data and signals as well as power distribution, while also providing modern connectivity options including:

• Bluetooth connectivity
• USB connection for software upgrades
• Data transmission and monitoring
• Support for future planned features

The turbine is also designed to work with a dedicated Android and iOS app*, giving pilots access to turbine information and functions directly from a compatible mobile device.

The RPM sensor has been upgraded to integrate all key parameters and timers directly into the turbine, helping to simplify the overall installation and electronics layout.

Powerful and Efficient

Despite its compact dimensions and 725g weight, the K86G4+ delivers an impressive 8.5kg+ of thrust under the specified conditions.

With a maximum speed of 176,000 RPM and a maximum EGT of 750°C, the K86G4+ is designed to provide the performance and response expected from a modern turbine power unit.

The turbine is powered by the KP300BL digital SBUS brushless pump, offering a modern and efficient fuel delivery solution.

Fuel Compatibility

The K86G4+ is designed to run on several commonly used turbine fuels, including:

• Diesel
• Jet A-1
• Petroleum
• Kerosene

The specified lubrication ratio for kerosene is 5%.

With a fuel consumption of approximately 280g/min, the K86G4+ provides a strong balance between performance and fuel efficiency for demanding turbine applications.

Why We Like It at Aerobertics

At Aerobertics, we appreciate turbine systems that combine high performance with practical installation and modern electronics.

The K86G4+ takes a different approach to traditional turbine installations by moving much of the electronics and data management directly into the turbine itself. The result is a cleaner installation, fewer cables and a more integrated system.

For pilots building a new turbine model or upgrading to the latest generation of turbine technology, the G4 platform offers a compelling combination of performance, connectivity and simplified installation.

The K86G4+ is a serious turbine for serious jet models — with the technology to match.
