Vittorazi Cosmos 300


SKU: N/A Category:


Cosmos 300 is the latest engine born in the Vittorazi house whose name tells a lot; is the synthesis of the company’s ambition to overcome its own limits to head towards conquering new flying possibilities by officially entering the market for trikes, hang gliders and minimal ultralights. An important step that only true leaders can dare.

Only those who have been designing paramotors for over 30 years know how important it is to minimize the volume and footprint of an engine. This is why we focused on the design of a compact layout and on reducing the number of components, gaining a uniform air flow towards the propeller, greater installation flexibility and low propagation of vibrations. Flying has never been so comfortable.

There are many technical features that characterize this engine conceived and designed to achieve the perfect balance between performance, safety and comfort. The power is always optimal, thanks to the liquid cooling system which has the function of controlling and maintaining the adequate temperature in different environmental conditions. Even the straight-toothed gear transmission with Skiving surface finish contributes to greater power thanks to low friction levels and perfect smoothness. The diaphragm carburetor also offers maximum performance in terms of power, consumption and power output even in critical atmospheric conditions. The Cosmos 300 is equipped with the Twin Spark technology of aeronautical derivation, a system consisting of two independent ignitions capable of offering double the safety. But there is more. The engine is equipped with the VDO sensor which monitors the cylinder head temperature and is designed for the EGT (exhaust gas temperature) sensor; two devices that ensure its maximum reliability. Flying with the Cosmos 300 is comfortable. The countershaft reduces the vibrations perceived during flight and reduces the stress of the components from a mechanical point of view, increasing the reliability of the entire aircraft. When the engine is idling, the clutch contributes to superior comfort and maximum safety during ground operations.

As per Vittorazi tradition, nothing is left to chance; it is the details that are essential. Not just performance, the new Cosmos 300 will amaze you with the time needed between one maintenance and the next. The first is expected after 100 hours of flight, bringing the Cosmos 300 among the engines of excellence in terms of build quality. Every single component has been studied because of the performance over time. So with Cosmos 300 you can only think about flying.
