SPH5 Introduction
Helicopters with glow and gas engines will no longer have to miss the advantages of turbine
engines. The generally available high energy or torque power band of turbine engines, is now
accessible through the SPH5 turbine reduction gear.
Therefore, as in the full scale industry, turbine engines will play a more prominent role in the RC
scale helicopter world.
These turbine engines have the same working principles as the full scale turbine systems.

The ECU controls the unit partially through the measurement of the rpm of the second stage turbine.
If the sensor for the second stage turbine is defective or not connected, the engine can be started (
up to 65 k rpm limited) but it will not reach its full rpm of 165 K rpm.
