The Per Il Volo Top 80 is an Italian single cylinder, two-stroke aircraft engine designed and produced by Per Il Volo of Galliera Veneta for powered paragliding. It was the first purpose-designed paramotor engine.[1][2][3]

Design and development[edit]

The Top 80 was developed specifically for the Per Il Volo Miniplane, which was introduced in 1989.[1][2][3]

The engine uses fan-cooling and a Walbro 24 diaphragm or Dell'Orto 17.5 basin-type carburetor. Designed for light weight as the overall consideration, the engine weighs 10 kg (22.0 lb), plus the exhaust system weight of 2.6 kg (5.7 lb). With the Walbro carburetor the Top 80 produces 11 kW (14.8 hp) at 9500 rpm. Power is delivered to the two-bladed wooden propeller though a reverse-turning gear box to reduce output net torque felt by the pilot during acceleration and deceleration[citation needed]. The oil filled gearbox can be fitted with 22/70 gears giving a reduction ratio of 3:182, 21/71 gears giving 3.381, 20/72 gears giving 3.60, 19/73 gears giving 3.842 or 18/74 gears with a ratio of 4.111. The engine also fits a centrifugal clutch that allows idling without turning the propeller, a useful feature in its main application on a paramotor, where it improves ground safety.[1][2][3]
