For those who have followed our journey at EnDTaS, the Lun-Class Ekranoplan has always been more than just a model to us—it is a symbol of audacious, boundary-pushing engineering. In our previous release (click here to open it in a new tab), we focused on capturing the sheer scale and imposing presence of the Soviet “Sea Monster,” providing a high-fidelity 1-meter replica for collectors and historians.
But for us, a static model is only the beginning. As a studio dedicated to Experimental Naval Designs, we asked ourselves: How do we move this behemoth from the shelf to the water?
From Display Piece to Dynamic Platform
The challenge of the Lun-class is its inherent contradiction: it is a massive, heavy-looking vessel that must remain light enough to exploit the ground effect. To translate this into a successful RC project, we couldn’t simply use the same geometry as the display model. Weight is the enemy of performance.
We are proud to introduce the Lun-Class Ekranoplan RC-Ready Lightweight Edition. This isn’t just a refinement; it is a complete engineering overhaul designed specifically for the motivated maker and RC enthusiast.

When the United States Coast Guard began planning its next generation of large ocean-going cutters in the early 1960s, the service had been operating converted World War II-era Navy vessels for nearly two decades. The ships were aging, increasingly difficult to maintain, and unable to fully meet the demanding operational requirements of a modern Coast Guard. What emerged from that planning process was one of the most successful and enduring cutter designs in the history of American maritime law enforcement — the Hamilton-class High Endurance Cutter, a vessel so capable and well-conceived that it would serve the Coast Guard for nearly half a century.
The initial contract for the lead ship, USCGC Hamilton (WHEC-715), was awarded to Avondale Shipyards in New Orleans, Louisiana in January 1964, with construction beginning shortly thereafter. Hamilton was launched on December 18, 1965 and commissioned on March 18, 1967, named for Founding Father Alexander Hamilton, the first United States Secretary of the Treasury and founder of the United States Revenue Cutter Service. She was the first genuinely new high-endurance cutter the Coast Guard had received in more than twenty years, and from the moment she entered service it was clear she represented a significant leap forward in capability. Originally envisioned as a large-scale procurement, long-range plans called for up to 38 cutters to be constructed over the following decade, but budget constraints and the wind-down of the international ocean stations program reduced the authorized number to just 12 ships, all built at Avondale between 1965 and 1972.
The Most Detailed RC-Ready Coast Guard Cutter Ever Designed for Home Builders
About the Legend Class National Security Cutter
The Legend Class National Security Cutter represents the pinnacle of the United States Coast Guard’s deepwater fleet capability. Built by Huntington Ingalls Industries in Pascagoula, Mississippi, these formidable vessels were designed to replace the aging Hamilton-class high endurance cutters and bring the Coast Guard’s operational reach firmly into the 21st century. Stretching over 127 meters in length and displacing more than 4,500 tons, the Legend Class is a true oceangoing warship in everything but name — capable of operating in the most hostile sea states on earth while conducting the full spectrum of Coast Guard missions.
Named after legendary figures in the history of the United States Coast Guard, these cutters are built for endurance, versatility, and projection. Their mission portfolio is extraordinarily broad: maritime law enforcement, counter-narcotics operations, search and rescue in open ocean conditions, fisheries protection, defense readiness, and even support for national security operations alongside the US Navy. Each vessel carries a sophisticated sensor suite, communication systems, and weapons fit including the Mk 110 57mm deck gun and the Phalanx Close-In Weapon System — making them among the most capable cutters ever operated by the service. USCGC Bertholf, the lead ship of the class and the primary photographic reference for this model, was commissioned in 2008 and has since logged thousands of operational hours across the Pacific, Atlantic, and beyond.
About This Model
This 3D printable model brings the Legend Class to life at 1:96 scale, producing a finished vessel approximately 1.3 meters long — a genuinely commanding presence on any shelf, display stand, or waterway. The model was developed using extensive photographic documentation of USCGC Bertholf as the primary reference, capturing the real ship’s proportions, deck arrangements, superstructure geometry, and surface details as faithfully as possible. Where classified or simply unavailable official blueprints left gaps, available technical drawings of similar vessel types were used alongside photographs to reconstruct accurate hull lines and structural relationships. The result is a model that is not merely inspired by the Legend Class — it is shaped by it, photograph by photograph, frame by frame.

The Formidable, Flawed Majesty of the Warship of the Line (includes a 1m model of Montebello-Mahmudiye ships of the line)
At the height of its era, the warship of the line was not just a vessel—it was an entire philosophy floating on timber and ambition. These ships were instruments of empire and emblems of statehood, their hulls stitched together with thousands of bolts, manned by hundreds of souls, and propelled by the complex interplay of wind, geometry, and blind luck.
Despite their stately appearances in oil paintings, life aboard these vessels was far from graceful. It was disciplined chaos, wrapped in a broadsided ballet of firepower and carried across oceans on sails the size of apartment buildings.
This article includes a stl file-pack to 3d print your own French 1m long Montebello or Ottoman Mahmudiye Class Ships of the line. The file pack is here. Please continue reading for a free display model of the ships.
USS Connecticut (BB-18) was one of the most advanced pre-dreadnought battleships of her time, designed to serve as the backbone of the U.S. Navy’s battle fleet.

Once upon a time in the vibrant heart of the Ottoman Empire, a grand vision was set into motion—the creation of the Abdülkadir ironclad warship. Though its story took a different turn than originally intended, the tale of this unfinished marvel remains an intriguing chapter in naval history.
In the mid-19th century, as naval technology advanced rapidly, the Ottoman Empire sought to bolster its maritime strength. The plan to construct a fleet of ironclad warships was born, and among these was the Abdülkadir. This ironclad was envisioned as a symbol of the empire’s modernization and technological ambition.
Designed to be a floating fortress, the Abdülkadir was intended to feature a robust iron-plated hull and powerful armament, capable of withstanding and delivering formidable blows in naval battles. It was to be a testament to the ingenuity of Ottoman engineers and shipbuilders.

As of 16 October 1912, Sulthanisar was assigned to the Bosporus Fleet Command. From 19 December 1912 on, she served at the Armoured Warship Division.
During the naval operations in the Dardanelles Campaign of World War I, the torpedo boat Sultanhisar was tasked with patrolling in the Dardanelles Strait. In addition, she daily transported German general Otto Liman von Sanders, who was the adviser and military commander of the Ottoman Army, between Eceabat and Gallipoli. On 29 April 1915, she received orders to return to Constantinople by sailing along the west coast of the Sea of Marmara. On the way, Commander Ali Rıza Bey changed his route and sailed eastwards in response to reports of the presence of a possible enemy submarine in that area.

In the annals of naval history, there are battles that stand out not just for their strategic significance but also for the sheer audacity and courage displayed by the sailors involved. One such remarkable encounter took place during World War I in the waters of the Marmara Sea, where the Australian submarine AE-2 faced off against the formidable Sultanhisar torpedo boat, creating a saga of bravery and maritime prowess.
The stage was set in April 1915, a time when the Great War was raging across Europe and its theaters extending into the Mediterranean. The Ottoman Empire, a key player in the conflict, controlled vital sea routes in the eastern Mediterranean, posing a threat to Allied shipping and military operations. The Allies, including Australia, were keen to establish naval dominance in these waters.
