Moster 185 Plus. The smallest and most powerful engine in its category.

It offers the best value for weight, power, thrust, comfort, quietness and reliability available on the market.

The main added value of this new version is given by the clutch. This integrated device significantly reduces vibrations at idle speed and it increases safety during pre-flight routine (propeller at rest). The vibrations are almost imperceptible at all engine speeds, while the weight distribution and the size of the engine minimize the torque effect.

The other notable improvement has been achieved with the introduction of the new exhaust system, extremely quiet and performing at the same time. The entire engine has been designed to obtain the minimum noise emission, which is attenuated by the air box, the transmission belt, a special "Db-killer" silencer, and the choice of the best propellers.

The "soft starter system" (3S) is one of the new advantages. It is a manual start system that allows the engine to start, both in flight and on the ground, with a single pull through the use of only one hand.

The Moster185 plus structure is basic and simple and it has a compact design (ideal and easy for control operations and maintenance). The engine develops a maximum power of 25HP at 7,800 RPM. Vittorazi agrees to communicate the values ​​of power, weight and static thrust in accordance with the actual values ​​measured.

It is recommended for a total weight of pilot + paramotor or trike ranging from 100 to 160 kg. The thrust is smooth and linear up to 75 kg with a 130 cm propeller (70 kg with a 122 cm propeller).

The fuel consumption of this engine, significantly reduced, is about 4.0 liters/hour considering a cruise flight.
