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.
The 250 is a conventional single-cylinder engine that weighs only 13 lb (6 kg). The engine features single- or optional dual-ignition, reed valve induction, free air cooling, tuned exhaust system, a 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 tuned exhaust supplied with the engine has been criticized as "cumbersome" and needing modification to fit most aircraft.[1]
