The Arrow 1000 is a four-cylinder, horizontally opposed, two-stroke, single- or dual-ignition, aircraft engine that was designed for float-equipped 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.
Development
The 1000 is a conventional four-cylinder engine that weighs 145 lb (66 kg). The engine features single or optional dual ignition, reed valve induction, free air cooling, tuned exhaust system, slide venturi-type Bing carburetors, 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 1000 produces 100 hp (75 kW), runs on premium unleaded auto fuel and has a recommended time between overhaul of 300 hours.[1][2]
