LEGO Technic 42181 VTOL Heavy Cargo Spaceship LT81 review 

Fact meets fiction with 42181 VTOL Heavy Cargo Spaceship LT81, a set born out of the LEGO Technic team’s imagination but designed with real scientific input.

In the ever-expanding universe of LEGO sets themed around space, 2024 sees models releasing across a wide number of themes all tying in together to create one cohesive line-up. 42181 VTOL Heavy Cargo Spaceship LT81 sets a new trajectory for fans, propelling them into the realm of interstellar exploration with a totally made-up spaceship.

It is somewhat of a departure for Technic, which usually releases sets based on real-life objects – but this model was designed with scientific advisors on board, so although it’s a thing of fantasy, it could in theory be used for deep-space exploration. And isn’t the LEGO Group’s primary aim to stimulate the minds of younger builders by sparking their imaginations?

This set is equipped with Vertical Take-Off and Landing (VTOL) capabilities and the Heavy Cargo Spaceship LT81 is designed to navigate the challenging terrain of distant planets. The model has several fun features and thanks to its white, orange and black colour scheme ties in with the rest of the current LEGO space-themed sets. 

But with so many space-inspired models on the market, does 42181 VTOL Heavy Cargo Spaceship LT81 offer enough to help it stand out?

— LEGO Technic 42181 VTOL Heavy Cargo Spaceship LT81 build —

The 1,365 pieces needed to construct 42181 VTOL Heavy Cargo Spaceship LT81 are spread across 10 numbered bags. There is also a separate bag containing cockpit pieces, fins and various larger Technic elements and an extensive sticker sheet used for adding a lot of detail to the final model.

The build begins as per many Technic sets with the construction of the framework and internal mechanisms. However, unlike a lot of Technic sets out there, because this is based on a fictional vehicle it’s very hard to tell exactly what you’re building and why. There’s a feeling you are just going through the steps without any goal in sight, which in turn creates a sort of disconnect from the model. It’s not the most enjoyable of starts to a set, and in fact the first three or four bags do feel somewhat like a chore to get through.

That said, there is a lot of smart engineering here, which eventually shines through and makes the set much more fun to assemble. The landing gear retracts and folds down simultaneously with the twist of a single cog; the cargo arms swing up and down with a press of a lever; and the engines rotate. A cantilevered cockpit is the cherry on top, and all these functions together add playability and interest to the model.

The bodywork demonstrates clever parts usage, creating interesting shapes, angles and curves that in places feel like they are almost hugging the framework. The top of the craft is left completely exposed and normally this would be a bit of a negative point, but here it allows for easy access to the vehicle’s main play features and also makes the spaceship one of the most swooshable LEGO Technic models ever.

It feels like a model perfectly pitched to its younger target audience. The build won’t offer a challenge to older fans and is over quite quickly, but there’s a lot of appeal for those around the 10+ age group. The play features are plentiful and fun, the stickers add a lot of cool details and it’s a sturdy, enjoyable model to mess around with.

The rover that makes up the smaller side build is a real surprise. It’s a brilliantly designed little vehicle and the jointed mid-section makes driving it around a lot of fun – for fans both young and old.

However, as interesting as the final model is, it just doesn’t have that appeal a model based on a real-life spacecraft might have had. Fictional space vehicles are nothing new within the LEGO back catalogue, but the space models found within System are a lot more fun to construct and look better on display. Technic vehicles shine when they are recreating real-life objects and sadly this set just doesn’t feel like it has that appeal.

There are no minifigures included within this set; it is a Technic model after all. However, minifigures can actually fit inside the cockpit and, thanks to the steering column included, they can actually grab on to the controls and stay seated while the model is in full flight.

42181 VTOL Heavy Cargo Spaceship LT81 is a fairly hefty model when finished and takes quite a while to piece together. There are over 1,300 pieces needed to finish the set and there are a number of fun play features and side builds too. With all that taken into consideration, this set is actually fairly decently priced.

There are an absolute galaxy full of space-themed LEGO sets currently on the market, so you’re really spoiled for choice. If you’re looking for something more grounded in reality, then the impressive Technic 42158 Nasa Mars Rover Perseverance would make for a fantastic set. Priced around the same as 42181 and containing nearly as many pieces, 42158 allows builders to recreate the actual Mars Rover that is currently still exploring the red planet.
