O.S. Engine OSMG0575 75AX ABL Sport Aircraft Engine  [OSMG0575]

High-performance fit for .60-size planes

The O.S. Engine OSMG0575 75AX ABL is aimed at pilots who want a reliable, high-output engine that drops into many existing mounts. It uses the same bolt pattern as the 61FX, which simplifies installation into standard firewalls.

Angular head for better airflow

The engine's angular head increases metal surface exposed to airflow, aiding cooling during hard flights and long sessions. That thermal management helps preserve consistent power output.

Power Box muffler that saves space

Supplied with the Power Box E-4040 muffler, the 75AX ABL benefits from extra internal volume while keeping external dimensions compact, a practical solution for tight engine bays.

Operating range and weight considerations

Displacing 0.75 cu in (12.3 cc), the 75AX ABL makes around 2.4 hp at 15,000 rpm and runs usefully between 2,000 and 16,000 rpm. Its mass of about 19.4 oz (550 g) keeps it balanced for many .60-size models.

For sport flyers wanting a compact, well-cooled engine with solid mid and top end, the O.S. Engine 75AX ABL is a practical choice that balances power and fit.
