The Arrow 500 is a twin-cylinder, horizontally opposed, two-stroke, single or dual ignition, aircraft engine that was designed for ultralight aircraft by Arrow SNC of Italy.[1][2] The Arrow family of engines are modular in design and share the same pistons, cylinders and gearboxes assembled around different crankcase designs, giving one-, two- or four-cylinder engines.[1] Arrow engines are no longer in production. DevelopmentThe 500 is a conventional twin-cylinder engine that weighs {{convert|88|lb|kg|0|abbr=on}}. The engine features single or optional dual ignition, reed valve induction, free air cooling, tuned exhaust system, a single slide venturi-type Bing carburetor, fuel pump, Nikasil cylinder coatings. The engine was offered with a gearbox reduction system that included a one way clutch. Starting is electric starter with no provision for a recoil starter.[1] The 500 produces {{convert|65|hp|kW|0|abbr=on}}, runs on premium unleaded auto fuel and has a recommended time between overhaul of 400 hours.[1][2] The tuned exhaust supplied with the engine has been criticized as "cumbersome" and needing modification to fit most aircraft.[1] Specifications (Arrow 500){{pistonspecs||ref=Cliche[1] |type=Twin-cylinder, horizontally opposed two-stroke aircraft engine |bore= |stroke= |displacement=500 cc (30.51 cu in) |length= |diameter= |width= |height= |weight={{convert|88|lb|kg|0|abbr=on}} |valvetrain=reed valve |supercharger= |turbocharger= |fuelsystem= |fueltype= |oilsystem=premixed oil and fuel |coolingsystem=air-cooled |power={{convert|65|hp|kW|0|abbr=on}} |specpower= |compression= |fuelcon= |specfuelcon= |oilcon= |power/weight= |designer= |reduction_gear=gearbox |general_other= |components_other= |performance_other= }} See also{{aircontent|see also=
