Horizontal steam engine Alex for RC boat 10 kgs

Horizontal Steam Engine Alex for Radio-Controlled Boat

The design of this range is based on several years of experience in building model boats equipped with steam engines.

CNC manufacturing in Germany allows for precise and consistent production, while retaining the characteristic mechanical aspect of a steam engine for RC boat.

Key Points

• Horizontal steam engine Alex, reference 22301.
• Set with horizontal boiler and steam condenser.
• Operates on propane or butane gas.
• Fully assembled, painted, checked, and adjusted installation.
• Designed for model boats weighing up to approximately 10 kg.

A Genuine Steam Power for Model Naval Engineering

The charm of a radio-controlled steamboat lies as much in its movement on the water as in the visible operation of its power system.

Unlike a traditional electric propulsion, a steam engine allows for the mechanical ambiance reminiscent of traditional steamboats.

Reference 22301 combines the engine, boiler, burner, control mechanisms, and condensation system into a single unit.

The modeler thus has an installation designed as a coherent unit rather than having to select each propulsion element separately.

The Alex steam engine is particularly suitable for small model boats with compact dimensions and relatively narrow hulls.

It can power models weighing up to approximately 10 kg.

The total weight is 1,580 g. This data should naturally be considered when choosing the boat and calculating the model's displacement.

Horizontal Steam Engine with Integrated Boiler

Reference 22301 stands out for its horizontal boiler. This configuration allows for integrating the steam installation into a model where the available space must be used efficiently.

The engine itself has a bore of 10 mm and a stroke of 14 mm. Its output shaft measures 4 mm in diameter, with a shaft height of 12 mm.

These features allow the modeler to have the main dimensions needed to verify the integration of the steam engine into the hull and prepare the transmission to the propeller.

Oscillating Steam Engine Ready for Installation

The engine is delivered fully assembled and painted. This finish allows for receiving a pre-prepared installation rather than a mechanical set requiring machining or complete assembly.

Before shipping, the installations are checked and adjusted. The modeler can focus on integrating the engine into their boat, connecting the various elements, and fine-tuning the model.

The engine includes an adjustable lubricator. This component contributes to the maintenance of the steam engine and its operation.

An inversion valve also allows for controlling forward and reverse operation as well as the speed of rotation.

This feature is particularly useful in the context of a radio-controlled boat as it allows for combining steam power with water use and appropriate propulsion control.

Complete Horizontal Boiler

The boiler is one of the essential elements of a steam engine for radio-controlled boats.

In reference 22300, it comes with the main equipment necessary for its operation and monitoring.

It includes:

• a safety valve;
• a water level indicator;
• a pressure gauge;
• a steam shut-off valve.

The pressure gauge allows for pressure control while the water level indicator monitors the water quantity in the boiler.

The safety valve and steam shut-off valve complement the installation's control equipment.

This design provides a genuine steam boiler for model boats, integrated into a unit specially designed for model naval engineering.

Operates on Propane or Butane Gas

The boiler is powered by a gas burner operating with propane or butane. The burner comes with its supply line.

The system also includes a chimney with an exhaust pipe.

These elements contribute to the realistic integration of the engine into the boat and enhance the mechanical aspect of a genuine model steamboat.

Finally, the propulsion system includes a exhaust steam condenser. This is an integral part of the installation delivered with reference 22301.

A complete equipment to simplify assembly

The Alex 22301 steam engine comes with many elements already assembled. The aim is to offer the modeler a complete installation rather than just a steam engine.

The supply includes:

• the steam engine;
• the adjustable lubricator;
• the reversing valve;
• the vertical boiler;
• the safety valve;
• the water level indicator;
• the pressure gauge;
• the steam shut-off valve;
• the chimney with exhaust pipe;
• the gas burner with its line;
• the exhaust steam condenser;
• finishing sticks for dressing the boiler;
• connecting pipes.

The whole set is assembled and painted. This presentation is an advantage for the modeler who wants to dedicate their time to the construction and equipment of the boat rather than the complete assembly of the machine.

A motorization suitable for boats up to 10 kg

The Alex 22301 steam engine is designed to easily power model boats weighing up to approximately 10 kg.

It finds its place in naval modeling projects seeking functional and realistic propulsion.

The horizontal configuration is particularly suitable for models where the available height allows for integrating the boiler under good conditions.

Before any installation, it is essential to check the dimensions available in the hull as well as the final weight of the equipped boat.

The positioning of the engine, boiler, and accessories should be planned during the design or assembly of the model.

A steam engine made in Germany

The Alex range is produced in Germany with modern CNC manufacturing. This manufacturing method provides great precision to mechanical parts and ensures a consistent quality of production.

This steam engine is intended for modelers looking for a motorization combining precision mechanics, realistic appearance, and operation suitable for radio-controlled steam boats.

Experience gained in creating model boats equipped with steam engines has also led to the evolution of the design after several series of improvements and numerous practical tests.

Accessories required for the Alex 22301 steam engine

Reference 22301 is delivered with the engine, boiler, and various connecting elements, but some accessories required for gas operation must be provided separately.

It is necessary to have a gas tank reference 22313, as well as a gas filling adapter reference 22316.

The propane/butane gas cartridge reference 60105 is also among the necessary elements.

For the maintenance of the engine, the steam engine oil reference 60100 is a useful accessory.

These elements allow completing the installation to have a set suitable for operating a radio-controlled steam boat engine.

Technical specifications of the Alex 22301 steam engine

A steam engine to bring a radio-controlled boat to life

The Alex 22301 steam engine is aimed at naval modeling enthusiasts who want to go beyond a simple static model.

With its vertical boiler, gas burner, condenser, and oscillating steam engine, it allows for creating a real propulsion installation for a model boat.

Its complete assembly, CNC manufacturing in Germany, and numerous integrated features make it easy to install in a radio-controlled steamboat project.

With a capacity of up to approximately 10 kg displacement, reference 22301 provides a comprehensive solution for hobbyists looking for a steam engine for RC boats, a horizontal boiler for model boats, and a functional steam power for naval modeling.
