O.S. MAX 18 CVR-MX 

The O.S. MAX 18 CVR-MX is a latest generation 2-stroke glow engine developed by O.S. Engines, one of the most reputable manufacturers in the world of modeling.

Designed for radio-controlled boats, it combines high performance, exemplary manufacturing quality, and easy tuning.

Designed for both sport and leisure use, the 18 CVR-MX benefits from all of O.S.'s experience in developing high-performance glow engines.

Its water cooling system allows it to maintain an optimal operating temperature, even during intensive use, to ensure consistent performance and excellent longevity.

A powerful 3.0 cm³ engine

With its displacement of 3.0 cm³ (.18 cu.in.), the MAX 18 CVR-MX develops up to 1.35 horsepower at 28,000 rpm.

Its very wide operating range, between 3,000 and 32,000 rpm, allows it to offer sharp accelerations and a particularly high top speed.

Its main technical characteristics are:

• Displacement: 3.0 cm³ (.18 cu.in.)
• Bore: 16.0 mm
• Stroke: 15.0 mm
• Power: 1.35 hp at 28,000 rpm
• Operating range: 3,000 to 32,000 rpm
• Weight: 232.6 g (complete marine version)

These characteristics make it an engine particularly suitable for RC boats seeking an excellent balance between power, weight, and reliability.

A recognized O.S. design for its quality

Like all O.S. engines, the 18 CVR-MX benefits from very high-precision machining and impeccable finishing.

Each component is designed to withstand very high speeds while maintaining great reliability over time.

Its carburetor ensures a regular fuel supply, facilitating adjustments and providing stable operation in all navigation phases.

Water cooling also helps preserve the engine's performance during long piloting sessions.

This quality of design explains why O.S. engines remain a reference among the most demanding modelers today.

Ideal for high-speed RC boats

The MAX 18 CVR-MX is intended for radio-controlled boats equipped with a transmission suitable for high-performance glow engines.

Its high power, quick revving, and light weight allow remarkable performance while maintaining excellent maneuverability.

Whether for restoration, refurbishment of an RC boat, or a new thermal navigation project, this engine is a reliable and high-performance choice.

Important information regarding accessories

Photographs may show the engine equipped with a flywheel and an exhaust manifold.

It is important to note that these two accessories were never originally supplied by O.S. Engines with the MAX 18 CVR-MX.

They were offered separately to allow the modeler to select the components best suited to their installation.

If your assembly requires these elements, they must be acquired independently from the engine.

Why choose an O.S. Engines engine?

For several decades, O.S. Engines has established itself as a global reference in the manufacturing of thermal engines for model vehicles.

The MAX 18 CVR-MX perfectly illustrates this expertise with its excellent level of performance, recognized reliability, and quality of manufacture.

Even today, it remains a particularly sought-after engine by enthusiasts of model naval modeling, whether to equip a high-performance remote-controlled boat, restore an iconic model, or enhance a collection of O.S. engines.
