LEGO Star Wars The Razor Crest Midi Scale – Alternate Build of 75440 AT-AT

No extra pieces required. Instructions are on Rebrickable: https://reb.li/m/246421

After completing my saucer starships, it felt like the right time to return to Star Wars. It has been a while since I designed my first Razor Crest, and the few hints of yellow and tan bricks hidden inside the otherwise grey dominant palette of 75440 started the idea. The model also pairs nicely with the upcoming The Mandalorian and Grogu, which is certainly an inspiring movie title.

The Razor Crest is an ST-70 assault ship manufactured by the Corellian Engineering Corporation, the same company behind the iconic Tantive IV. Jon Favreau’s original design brief to Lucasfilm referenced the A-10 Thunderbolt “Warthog”, most notably through the use of two large turbofan engines. Their unusual placement reduces ingestion risk and allows the engines to run while the craft is serviced and rearmed, shortening turnaround time.

The Razor Crest features top mounted wings with massive engines positioned at the wingtips. This configuration gives the ship impressive speed and manoeuvrability, allowing it to operate alongside much smaller starfighters. Recreating those engines took many design iterations. The biggest limitation was part availability, as the set only includes seventeen cheese slopes including one spare, which is not enough to fully shape both engines symmetrically. On the plus side, I finally found a satisfying use for the two 1x4 Technic gear racks in the engine assemblies, pieces I could not integrate into my other three alternate builds from 75440.

Small levers were a perfect fit for the twin blaster cannons, while brackets form the shape of the nose section. Two differently coloured tiles help disguise the gap between the brackets. The entire AT-AT contains only a single curved slope, and fortunately that one piece was enough to serve as the Razor Crest canopy windscreen. I love simple solutions to design challenges.

To capture the angular, industrial wedge profile of the Razor Crest, I built the fuselage using six angled panel sections across the hull. Most of these panels rely on three or four stud connections for clutch power. Structural strength is a major focus in all my designs, especially since my family loves to swoosh models around. That said, the angled side panels can be pushed inward at their joints. If this happens, I recommend removing the central panel, reattaching the loose panel, then reconnecting the three panel section as a whole to the trans-clear side studded brick.

When handling the model, pick it up by the two engines and hold the ship around the central fuselage panels while swooshing. The structure is very solid in these areas. If the angled panels are accidentally pushed in, simply reattach them using the method described above.

To complete the display, I also designed Mando’s N-1 Starfighter to accompany the Razor Crest. I am proud to say the N-1 is highly accurate and includes its own display stand. Naturally, the Razor Crest received a larger stand to balance its increased size.

Overall, this Razor Crest was a satisfying return to Star Wars and a great way to push the limits of what 75440 can offer as a donor set. Working within the strict part constraints forced more deliberate design choices, especially around the engines and angled fuselage panels, and ultimately helped define the character of the model. The result is a relatively sturdy, swooshable build that stays true to the Razor Crest’s rugged, industrial identity while remaining practical to handle and display. Paired with the N-1 Starfighter, the two models make a cohesive and character driven display that feels right at home on the shelf.
