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

Engineered for reliable .60-size operation

The O.S. Engine OSMG0575 75AX ABL is aimed at model pilots who need steady power and straightforward installation. It accepts the same mount pattern as the 61FX, making it a practical upgrade candidate for many airframes.

Angular head aids thermal control

The angular head construction increases the area available for heat transfer, helping to keep running temperatures in check during prolonged or aggressive flying sessions.

Power Box E-4040 muffler balances size and flow

Fitted with the Power Box E-4040 muffler, the engine benefits from additional internal volume while keeping the external footprint small, allowing for tidy installation in tight cowlings.

Operational data and handling notes

With 0.75 cu in (12.3 cc) displacement the 75AX ABL can deliver around 2.4 hp at 15,000 rpm and is useful across a 2,000 to 16,000 rpm band. Its weight of approximately 19.4 oz (550 g) keeps it suitable for a wide range of .60-size designs.

The 75AX ABL is well suited to experienced hobbyists seeking a compact, well-cooled engine with the power profile needed for sport and competitive flying.
