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

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]

The tuned exhaust supplied with the engine has been criticized as "cumbersome" and needing modification to fit most aircraft.[1]

gollark: Might be.
gollark: It might not be that, but I couldn't find an off thing in the Config.
gollark: We'd make less than what the recyclers cost, but sure.
gollark: The wiki says```A flag, mod_IC2.suddenlyHoes (added in 1.337), can change the probability weight of Wooden Hoes to 9001, reducing the chances of getting anything other than Wooden Hoes to 0.53% (about 1 in 186).```so I think it's some sort of overrunning april fools'...
gollark: I think the weights got messed up.
