O.S. Engine OSMG0575 75AX ABL .60 Airplane Engine  [OSMG0575]

Optimized power for .60-size models

The O.S. Engine OSMG0575 75AX ABL is built for .60-sized aircraft pilots who want reliable performance and an easy fit into existing mounts. It shares the bolt pattern of the 61FX, making upgrades straightforward without heavy modification.

Head design that improves cooling

The angular head on this 75AX ABL increases exposed surface area to help dissipate heat during extended flights. Effective cooling helps maintain consistent runs at higher output settings and reduces thermal stress on the engine.

Compact Power Box muffler with extra volume

This engine ships with the Power Box E-4040 muffler. The design keeps the unit compact while offering increased muffler volume to support stronger power delivery in crowded engine bays.

Performance figures and handling notes

With a displacement of 0.75 cu in (12.3 cc), the 75AX ABL produces about 2.4 hp at 15,000 rpm and works well across a practical RPM range of 2,000 to 16,000. At roughly 19.4 oz (550 g) it balances output with manageable weight for most .60-size airframes.

For club pilots and competitors looking to upgrade a .60-size model, the O.S. Engine 75AX ABL delivers a practical blend of cooling, power, and compatibility that works well for aerobatics and sport flying.
