O.S. Engine OS-1AD00 - Machined glow engine for reliable flight

The O.S. Engine OS-1AD00 brings CNC-level precision together with a compact design tailored for model aviation. Favoured by pilots who appreciate engineered tolerances and consistent running, this engine suits helicopter installations and light fixed-wing aircraft requiring a nimble powerplant.

Component Quality and Visual Details

Key parts including the crankcase and head are CNC machined to ensure accurate fits and longevity. Gold and platinum plated variants extend the finish to the carburetor and glow plug, while black anodised prop hardware and a matte black silencer complete the look with a restrained, functional style.

Speed Range and Weight Considerations

Measured figures include a 1.79cc displacement, 13.44mm bore and 12.65mm stroke, producing about 0.31hp at 18,000 RPM. The usable rev band runs from approximately 2,500 to 18,000 RPM. The engine weight is 157.8g, with the silencer at 38.5g, keeping the installation light and responsive.

If you need a compact glow engine with refined machining and a high rev ceiling, the OS-1AD00 delivers a dependable package. It fits well where light weight and steady power delivery are priorities.

Select a prop that allows the engine to spin into its upper rpm band without stalling. Consult recommended prop charts and aim for safe peak rpm near the specified 18,000 mark.
Yes, replacement and upgraded silencers exist from OEM and aftermarket suppliers. Choose one rated for the OS-1AD00 to maintain correct back pressure and fitment.
Confirm fuel delivery, glow plug condition and needle settings first. Also inspect for air leaks at the carburettor and ensure the prop nut is secure to avoid vibration-related issues.
The OS-1AD00 offers the precision and rev range that many competitive pilots prefer, but competition suitability depends on class rules and specific performance needs. Match the engine to the event's requirements for best outcome.
