LEGO SET 31126 - Alternate build | Supersonic-jet
Discover the Sky-High Possibilities of LEGO Set 31126 – Supersonic Jet Alternate Builds
The LEGO Creator 3-in-1 series is all about unlocking creativity through reimagining what’s possible with a single set of bricks—and LEGO Set 31126-1, the Supersonic Jet, is no exception. While the official model is a sleek, futuristic aircraft, this set hides many alternate adventures within its 215 pieces. If you love jets, spaceships, and flying machines—or if you enjoy repurposing a limited brick palette into brand-new creations—you’ll be thrilled by what the community has designed.
From real-world military jets like the F-15 Eagle and F-4 Phantom to pop culture nods like an X-Wing and Klingon Bird of Prey, this set has become a launchpad for imagination. And it doesn’t stop there—several builders have turned this jet into submarines, jet skis, space shuttles, and even skyscrapers!
Whether you’re looking to create a playable model for swooshing around the room or a clever display piece to show off your building skills, these alternate builds offer something exciting for every LEGO fan.
