The Arrow 1000 is a horizontally opposed, four-cylinder, two-stroke aircraft powerplant, available with either single or dual ignition systems. It was engineered by the Italian company Arrow SNC specifically for ultralight aircraft equipped with floats.[1][2]
Engines in the Arrow series utilize a modular architecture, sharing common components such as pistons, cylinders, and gearboxes, which are arranged around varying crankcase designs to create one-, two-, or four-cylinder configurations.[1] Production of Arrow engines has since ceased.
Development
This model is a traditional four-cylinder engine with a weight of approximately 145 lb (66 kg). It offers either single or optional dual ignition and incorporates reed valve induction, free air cooling, a tuned exhaust system, and slide venturi Bing carburetors. Additional features include a fuel pump and cylinders coated with Nikasil. The engine is available with a gearbox reduction drive that incorporates a one-way clutch. Electric start is standard; however, it does not support recoil starting.[1]
Generating around 100 hp (75 kW), the engine runs on premium unleaded automotive fuel and has a recommended overhaul interval of 300 hours.[1][2]
The supplied tuned exhaust system has been noted as somewhat bulky and often requires modification to fit various aircraft installations.[1]
