KingTech K-30TPG4+ Turboprop Engine

The KingTech K-30TPG4+ is a high-performance turboprop engine designed for demanding RC aircraft applications where turbine power, compact dimensions and realistic propeller-driven operation are required.

As part of KingTech's G4 generation, the K-30TPG4+ incorporates advanced electronic integration between the engine and ECU, together with a digital bus brushless fuel pump and brushless starter motor.

Its relatively low weight of approximately 1.2 kg makes it particularly attractive for scale aircraft and other performance-oriented RC applications where weight and power-system efficiency are important.

G4 Generation Technology

The K-30TPG4+ incorporates KingTech's G4 technology platform, including:

• SBus data transmission
• Engine and ECU integration
• Operating parameters and total engine run time recorded by the ECU
• External Data Relay Module (DRM) for data, signal and power transmission
• Digital bus brushless fuel pump
• Brushless starter motor
• Integrated FOD screen
• Micro USB connectivity for future wireless/mobile connectivity
• Automatic post-run cooling protection

The G4 system is designed to provide improved monitoring, control and integration of the turbine power system.

Designed for RC Turboprop Aircraft

Unlike a conventional turbojet, the K-30TPG4+ drives a propeller through its turboprop configuration, making it suitable for RC aircraft designed around a turbine-powered propeller system.

The manufacturer recommends:

• 3-blade 18×12 propeller
• 3-blade 18×16 propeller

The appropriate propeller should be selected according to the aircraft, operating conditions and manufacturer's recommendations.
