The structure of the engine Moster 185 is simple, streamlined and compact. The complete weight of the engine is 12.9 kgs in pull starter version, the installation "plug&play" is very fast and simple on every cage. The thermic group is cooled with the air generated by the extraction flow of the propeller, in direct tramission with the crankshaft.

The motor develop a power of 25 hp at 7.800 rpm,is particularly suitable for a weights pilot + paramotor or trike between 100 and 160 Kgs (200 to 350 pounds). The engine`s not been studied for the tandem use or for a take off weight over 160 kgs. The thrust is regular, smooth, gentle up to reach 75 kgs (165 pounds) with a 130 cms (51 inches) propeller or 70 kgs (155 pounds) with 122 cms (48 inches) propeller.

The motor starts on the ground or during the flight in unique way considering the capacity 185cc and avoid the installation of the decompressor valve. The vibrations are almost imperceptible on every speed, while the distribution of the weights and the dimentions of the motor, reduce the torque effect given from the propeller.

The motor has been studied for getting a limited noise, attenuated by airbox, from the belt transmission, from a good silencer and from the choice of the best propellers. The consumption of this motor is about 3,5 liters / hour considering a cruise flight.
