Arrow 500 Type Two-stroke aircraft engine National origin Italy Manufacturer Arrow SNC

The **Arrow 500** is a twin-cylinder, [horizontally opposed](/source/Horizontally_opposed), [two-stroke](/source/Two-stroke), single or dual ignition, [aircraft engine](/source/Aircraft_engine) that was designed for [ultralight aircraft](/source/Ultralight_aircraft) by [Arrow SNC](/source/Arrow_SNC) of [Italy](/source/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.

## Development

The 500 is a conventional twin-cylinder engine that weighs 88 lb (40 kg). The engine features single or optional dual ignition, reed valve induction, free air cooling, tuned exhaust system, a single slide venturi-type Bing [carburetor](/source/Carburetor), fuel pump, [Nikasil](/source/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](/source/Recoil_starter).[1]

The 500 produces 65 hp (48 kW), runs on premium unleaded auto fuel and has a recommended [time between overhaul](/source/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]
