Turbine engines are representing the ultimate stage in the scale models realism. The miniaturization work of turbine engines has been started about 10 years ago, and their current status of development is showing great power, reliability, and all of this without vibrations.
The power that gas turbine is so large that we can fly today giant scale models , totally impossible to consider until now. A few years back, scale model helicopters were restricted within the 2 meters range and used a 2 strokes single piston gas engine. These scale models were terribely loaded by their own engine's weight, and we were lacking margin to add more scale details. Also, we missed a lot of room inside the cockpit to be able to do a nice scale finish. Today, turbines are allowing to fly models up to 3 meters of rotor diameter, with a huge avalable space in the cockpit. In fact, turbine mechanics are very compact in size. Their power output is so large that you can push the finish to the extreme without to encounter weight limitation right away.. Turbine engines are running on kerosene or heavy fuel, their start-up and shut-down sequences are entirely automatic.
