O.S. Engine OSMG0715 15CV-A Aerobatic Ready Glow Engine  [OSMG0715]

Aircraft-Adapted O.S. Engine 15CV-A

The O.S. Engine 15CV-A, known by its model number OSMG0715, brings an aircraft-focused layout to a well proven small engine. Converted from a buggy design, this version features an aircraft-style cylinder head and a rotary carburettor to improve throttle stability in the air.

Design Highlights for Flying

The O.S. Engine 15CV-A is engineered with aviation use in mind. Dual front and rear crankshaft bearings boost mechanical reliability and help maintain steady power output, while the remote needle valve reduces the need to handle the prop during tuning.

Power Delivery and Usable Range

Finished with a blue crankcase, the unit delivers about 0.50 bhp at 18,000 rpm and operates efficiently between 2,500 and 19,000 rpm. That range offers good responsiveness for sport routines and precise aerobatic manoeuvres.

For pilots seeking a compact engine with good throttle control, the O.S. Engine 15CV-A is a practical choice. It combines a robust mechanical layout with features that simplify field tuning and reliable in-flight behaviour.
