O.S. Engine MAX-11AX Gold 80th Anniversary Edition with OS-1AD00 performance tuning  [OS-1AD00]

OS-1AD00 by O.S. Engine - Compact CNC glow performance

The O.S. Engine OS-1AD00 is aimed at model pilots who value precise machining and usable power. Built with CNC-machined crankcase and head, this engine offers a strong foundation for agile flight. Though optimised for helicopter roles, its characteristics suit a variety of lightweight aeroplanes with an appetite for high revs.

Precision Components and Finish

Quality machining defines the OS-1AD00. The crankcase and head are CNC-cut for accurate fits, helping the engine run smoothly under load. Decorative gold or platinum plating is applied to the carburetor and glow plug on selected finishes, while the black anodised prop washer, nut and matte silencer offer a low-key aesthetic that holds up in the field.

Engine Characteristics and Speed Band

Technical figures underline the engine's capabilities: 1.79cc displacement, a 13.44mm bore and 12.65mm stroke produce roughly 0.31hp at 18,000 RPM. Expect a practical operating window from about 2,500 up to 18,000 RPM, and a total engine mass of 157.8g with the silencer adding 38.5g.

With a light overall mass and a high rev ceiling, the OS-1AD00 provides a balance of form and function. It is a sensible selection for pilots wanting a compact glow motor that performs well across different flying conditions.
