The verdict

This is the set where I felt the most torn all year.

The X-wing itself is a friendly, playable little Red Five, and the SMART Brick that makes R2 scream when you swoop the ship overhead genuinely lit up every kid who got near it. But at its price this is one of the more expensive 581-piece sets Star Wars has ever asked for, the synthesised sound is thin and buzzy, and half the reviews on LEGO's own store are one star. If you are buying for a six-year-old who wants their ship to talk back, this delivers. If you want a display X-wing, buy a normal one and save yourself a lot of money.

The full review

What it is

Luke's Red Five is the set LEGO chose to introduce its new SMART Play system to the Star Wars world, and that context matters before you judge it. Underneath the technology it is a compact, chunky Red Five X-wing sized and shaped for small hands, with a cockpit for a pilot Luke, wings that open into attack position, and a clutch of side builds (a communication center, a transporter, and an Imperial turret) that turn the box into a little diorama. The first time I banked the finished ship over the SMART Brick and heard R2 let out his panicked scream, I grinned in spite of myself. That reaction is the whole pitch, and with a child in the room it works.

The catch

Here is where I have to be straight with you. This set carries a much higher price than a normal 581-piece Star Wars set, because you are paying for the SMART Brick, the charger, and five SMART Tags as much as the plastic. The sound that comes out of that brick is composed live on a tiny onboard synthesiser rather than played from real recordings, and it shows: it is thin, a bit buzzy, and nowhere near the crisp effects kids hear from a tablet. Adult reviewers have been blunt about it, and on LEGO's own store the ratings split almost evenly between five stars and one star, which tells you exactly how polarising this is. As a model, the X-wing is also plainer than what you would get building a standard set for the same outlay.

Who it's for

So who should actually get this. If there is a six or seven-year-old in your life who is obsessed with Star Wars and loves toys that respond to them, this is a real hit, and the reviews from parents and grandparents back that up: the children are having a wonderful time. The interactive layer gives an early builder a reason to keep playing after the last brick is in. But if you are an adult collector, or you want a good-looking X-wing for a shelf, I would steer you firmly away and toward a conventional set, where every dollar goes into the build. This is a toy first and a model second, and it is priced like the experiment it is.

The parts story

What the build is actually like, and the pieces worth knowing about.

Building this is deliberately gentle, and I mean that as a compliment for the audience it is aimed at. The instructions break the set into separate mini-builds, each with its own booklet, so a young builder can finish the transporter, play with it, then move on to the turret or the ship itself without staring down one long marathon. The X-wing goes together with sturdy, forgiving connections and opening S-foils, and the side builds keep the momentum going. It is not a technically clever build for an experienced hand, but it is paced beautifully for a child.

The real story here is not a new mold or a rare recolor, it is the electronics. The SMART Brick is a wirelessly charged unit packed with a motion sensor, accelerometer, light sensing, and a sound sensor, and it reads the set's five SMART Tags (each a 2x2 studless tile carrying a unique digital ID) through near-field magnetic communication to decide what to sound like. The two SMART minifigures of Luke and Leia carry their own IDs too. It is a genuinely novel piece of LEGO engineering. Just know that on the traditional parts-value front, where we usually weigh printed and rare elements, this set is thin, because the value is meant to live in the brick, not the bricks.

Fun facts

01The SMART Brick was unveiled at CES 2026, making Luke's Red Five one of the first Star Wars sets tied to LEGO's debut electronics platform.
02The SMART Brick does not store or play any audio files; every sound is composed live on a tiny onboard synthesiser based on instructions sent by the tags.
03Each SMART Tag is a 2x2 studless tile that tells the brick what to become, and the system communicates through near-field magnetic signals rather than Bluetooth or WiFi.
04On LEGO's own store the set is one of the most divisive Star Wars releases in memory, with roughly 40 percent of reviews at five stars and 43 percent at one star.
