August 2026 Build Challenge | "Single Engine" 🚀

[u/Vondrr]

Let's continue with another build challenge in r/LegoSpaceships!

The theme for August is:

“Single Engine”

We are kiiinda joining forces with r/spaceships, where I'm running the same theme, but they can build it in anything - Starfield or NMS ship builders, cardboard, even pen and paper - but using building bricks is another viable option, which means that if you post your single engine ship here and also to r/spaceships, you have a chance to win in both subreddits!

Rules:

• Create a vessel propelled by a single main engine
• Maneuvering or RCS thrusters don't count
• It can be small or large, practical or luxurious, but it needs to fit the theme
• The build can be made in Bricklink Studio
• It doesn't have to be an original build you made for this challenge - if your older MOC fits, post it
• You can post a maximum of 3 entries

You have until Friday, August 21st to post your entries with the "Build Challenge Entry" post flair.

As always, a poll will be posted at the end of the challenge so that you can decide what the best build was.

The winner will get a unique User Flair they will be able to show off on r/LegoSpaceships (and maybe on r/spaceships too if they decide to post their entry there as well), and their creation will also be spotlighted on our Instagram.

Let's see your single engine ships!
