polini thor 80 lc

Thor 80 is Polini’s new mini 2 stroke paramotor engine is compact in size, liquid-cooled.

The Thor 80 weighs 12.5kg. It is liquid cooled, not unique in the paramotor world but this one has a forced air cooled radiator. See the diagram below, engine mount layout is per other thor engines 130, 190, 200. This one has a plastic shield ducting air from an internal fan behind the starter up through the radiator, allowing for the radiator to be kept tight and tidy behind the pilot.

Measuring 41cm wide x 54cm high & 30cm deep is it compact, especially given it has a radiator.

The power plant measures 86cc 50×44 for 17 hp at 10,450 rpm, compression ratio 14.01

The engine comes with Polini own CP d.21 carburetor or it can be ordered with the more familiar Walbro WG8 carburetor. A dry-centrifugal clutch, with 3.58 gear reduction with helical teeth in oil bath. As this engine has a clutch and gear reduction it is also flash starter equipped.

Thrust test video suggest 55kg with 130cm prop.  The liquid cooling will aid in economy and we expect the little engine to be fairly frugal.
