The O.S. Engine 15LA Silver, from the OSMG0016 range, offers compact sport-level output for radio controlled aircraft. Its focus is on reliable construction and easy-to-manage features that suit frequent flying and simple maintenance.
An enlarged cooling fin surface helps the engine shed heat more effectively, which reduces thermal load and helps prevent seizure during longer or more aggressive flights. That improved heat control contributes to longer service intervals.
Strengthened webbing in the crankcase supports the engine through throttle changes and operational stresses, preserving alignment and durability through normal flying and occasional hard landings.
The needle valve is engineered with a snug fit and O ring to stabilise fuel flow, making trims more predictable. The upward-pointing fuel inlet eases refuelling and draining, so routine checks and bench work are less fiddly.
The O.S. Engine 15LA Silver is well suited to pilots wanting a compact, service-friendly sport engine that holds up to regular flying demands.
