Other sizes and scales apart from the two above (or other model types) available upon request - just message us for more info.


This model replica is painstakingly hand carved and then hand painted out of solid kiln dried mahogany wood(from renewable sources) by our highly experienced and talented craftsmen at our Filipino owned factory near the original Clark Air Base in Pampanga and takes about 9-10 weeks to manufacture. Production in our factory is supervised by our own resident British Pilot who ensures that exact blueprints are used for these meticulously detailed scale models custom manufactured and precisely engineered to your exact specifications and that will be cherished by all.

The model will be exactly as you see in the above and below images in terms of detailing (doors, windows, lights, control surface markings, antennas etc.) color and size so we would kindly ask you to study the images very carefully (if you require higher resolution images please ask) to make sure that the model as you see is the 100% the same version you require or expect. If there are changes that you require or mistakes or deference's in relation to the real aircraft before ordering, please message us and we will setup an alternative listing to match your own requirements. We request your understanding on this matter due to the fact that these handmade models are traveling in many cases halfway around the world and any misunderstandings or mistaken expectations must be addressed at this as point of time as we cannot be held responsible for the costs involved in returning and replacing the model. The model will be shipped with the stand you see in the images although you may request if you like to change to either 1, 6 or 7 as in the attached image examples (just message us if a change is required).

It is our aim to continue to be a "sustainable" manufacturer avoiding the use of man-made materials wherever possible such as plastics, resins or metal in an attempt to reduce our Carbon Footprint and to protect our environment for generations to come. Our models are "works of art" and not to be confused with mass made plastic kits or diecast (die cast) look-alikes. We are proud Filipino's exporting to all parts of the globe and creating employment opportunities in an impoverished part of our country.

100% handmade models naturally come at a higher price than off the shelf, plastic or diecast (die cast) models but it may interest you to know that an average regular size fixed wing or helicopter model takes on average a total of 26 dedicated Man Hours of work to produce. During this time the model transitions through over 40 different manufacturing stages and processes. The 26 hours are not consecutive and require in-between many days (and in some cases weeks) of drying and curing time as they pass from one department to another making the overall production time from an outsider?s point of view appear rather lengthy. Given these facts the time period we quote for production alone is very standard for our type of industry and among our close competitors.

The fully assembled model comes with a stained solid mahogany (or mahogany with steel arm) stand and is ready to display on your desk, bookcase or wherever you desire. The photographs you see have not been manipulated or digitally edited - they are exactly as the model looks in real life, but unfortunately even digital photography cannot do full justice to the look and feel of the model once you receive it!

We are able do this because of the direct manufacturing and selling basis of our business - models direct from the factory and not from an intermediary or trading / marketing company.

Martin JRM Mars: Coulson’s Giant Firefighting Seaplane

The Martin JRM Mars is one of the largest flying boats ever built and has become an iconic symbol of aerial firefighting. Originally designed as a long-range transport aircraft for the U.S. Navy during World War II, the Mars has found a second life in civilian operations under Coulson Aviation, where it serves as a specialized water bomber capable of delivering massive quantities of water or fire retardant to combat wildfires. Its enormous size, combined with unique design features, makes it a one-of-a-kind asset for large-scale firefighting missions.

Design and Features

The Martin JRM Mars is a four-engine, long-range flying boat. Its design prioritizes both cargo capacity and endurance, enabling it to carry enormous loads over great distances. Some notable features include:

Originally built to transport troops and cargo across the Pacific during World War II, the Mars was the largest operational seaplane of its era. Its robust construction allowed it to handle the demands of firefighting, including repeated low-altitude passes over hot, turbulent air near wildfire zones.

Coulson’s Firefighting Operations

Coulson Aviation acquired the remaining Martin JRM Mars aircraft and converted them into giant water bombers. The Mars is capable of carrying up to 7,200 gallons (27,000 liters) of water per sortie, making it one of the most capable aerial firefighting platforms in the world.

Coulson’s Mars aircraft operate mainly in Canada and the western United States, regions prone to large and fast-moving wildfires. Their combination of payload capacity and endurance allows them to support other firefighting aircraft, helicopters, and ground crews in large-scale operations.

Operational Challenges and Advantages

Flying a seaplane of this size is not without challenges. The Martin JRM Mars requires long stretches of calm water for takeoff and landing, and its massive size limits maneuverability compared to smaller aircraft. However, its payload capacity and efficiency make it invaluable in situations where many smaller aircraft would be required to achieve the same effect.

Coulson’s Mars operations also highlight the advantages of repurposing historical aircraft for modern needs. These planes offer a combination of heritage engineering and modern retrofits, including updated avionics, safety systems, and firefighting-specific modifications.

Legacy and Impact

The Martin JRM Mars is not just a relic of World War II—it is a living, flying example of adaptability. Its transformation from military transport to firefighting giant demonstrates how legacy aircraft can continue to provide critical value decades after their initial design. Under Coulson Aviation, the Mars continues to save lives and protect property, reinforcing its place in aviation history as both a technological marvel and a practical tool for modern emergency response.
