This ultra-modern two-stroke engine is characterized by its low power-to-weight ratio.  The powerful engine can also be relied on in continuous operation. The well-thought-out design relies on a liquid cooling system, which guarantees optimal heat dissipation from the combustion chamber. Especially during cruise flying, this engine impresses with its quiet engine running.

1,25m propeller

The 1.25 m propeller from Helix Carbon, perfectly matched to the engine, is made of unbreakable, carbon fiber and meets the highest safety standards. Compared to other propeller manufacturers, the Helix Carbon propellers are particularly characterized by their smooth running and the much more efficient blade profile.

 

Airbox

The airbox is available on all Polini engines. It filters the air and dampens the intake noise extremely effectively.

 

Exhaust with Helmholtz

Typically for Polini engines, the resonance exhaust is specially designed for flight operations. A Helmholtz resonator developed by Fresh Breeze ensures even more performance. The exhaust is multi-part and connected by break-proof springs to decouple the vibrations from the exhaust. The shapely muffler reduces engine noise to a minimum.

 

Transmission

Due to its design, the fully enclosed gearbox is low-maintenance and almost wear-free. The reduction ratio of 2.8: 1 is designed so that the maximum engine efficiency is developed at 8000 rpm. The centrifugal clutch is integrated in the gearbox.

 

Cooler

The streamlined cooler supports the liquid cooling system in its work and guarantees thermal stability. This means that the engine temperature is optimal even for long climbing phases.

 

Fuel pump

A small, light fuel pump supplies the carburetor with fuel. The pump does not need any electricity at all because it takes advantage of the changing pressure conditions in the crankcase. This small feature enables the use of deep-lying tanks, which has a positive effect on the center of gravity of our aircraft.

 

Engine unit

In this configuration, the engine is designed for the "Pro SportiX" system. The entire periphery of the engine is taken up by the engine frame.

 

Electronics

A generator with a power of 80 W at 5500 rpm is installed in the engine and is supported by a battery. This electrical system enables advantages such as electrical starters, electricity for radio etc.

 

Carburetor

The slide carburetor prepares the mixture for optimal combustion. This carburetor concept entails a linear increase in power. With this carburetor, the pilot has very sensitive control over the engine.
