O.S. Engine OSMG1426 25LA-S Classic Control-Line Motor  [OSMG1426]

Reliable Running with the O.S. Engine OSMG1426 25LA-S

The 25LA-S, designated OSMG1426, is crafted to provide steady, predictable performance for control-line models. It aims to reduce the tuning headaches often associated with carbureted engines.

Steady Throttle from a Venturi Feed

Replacing the typical carburetor, the venturi feed keeps the mixture and rpm more constant under load, which is valuable when precision is required. The remote-mounted needle valve is located at the rear for safer operation and straightforward adjustments trackside.

Engineered for Tough Use

A one-piece crankcase reinforced with webbing increases rigidity and longevity, while bronze bushings lower internal friction. The longer crankshaft and flat prop washer provide added thread for prop retention, and the squared heat sink head with larger fins promotes better heat dispersion.

The O.S. Engine 25LA-S is a pragmatic choice for control-line flyers seeking a robust, consistent engine that is simple to set up and maintain.
