Review: 31086-1 - Futuristic Flyer

Alternate Builds and B-models, Sub-Sets and LEGO Idea reBuilds, together with MOVs and Modifications and Free, Premium and Freemium MOCs, these are LEGO creations that, besides Rebrickable, no other website in the world can offer you. If you have no idea what I am talking about, then allow me to review set 31086 Futuristic Flyer and show you all it creative possibilities.

The Build


I will admit it. My favorite theme is Creator 3-in-1. The reason is simple. I like building. The basic process of looking for parts, picking them up and orientating them, and then clicking them in their right place; that process is the most relaxing experience I know off, especially when I am building from an BI, a Build Instruction, so I don't even have to think about which parts to pick, and where to put them.

Building from a BI, I have recently noticed, is much like reading; the more you practice, the better you become at it. I'll get back to that later on. But in terms of opportunity for BI building, the LEGO Creator 3-in-1 sets undoubtably hold the highest scores. Each set allows you to build three different models from printed instructions, and usually LEGO adds a fourth model model with digital instructions you can download from their Service website. In Rebrickable we call the main model the A-model, and the additional models B-models. Using only the parts with the set, you can only build one of them at the same time, and you have to take it apart to build another.

Sometimes a set contains two or more distinct models. Those we call sub-sets, and you can build all of them together using only the parts within the set. And when LEGO depicts an extra model on the box, but doesn't provide instructions to build it, we call those LIBs, or LEGO Idea reBuilds, and we provide inventories for all of them. Check out our help page on Set Types if you want to know more.

But using the parts from a single set, you might also try to build some of the Alternate Build MOCs, which can be either Free or Freemium, with instructions freely available; or Premium, where you have pay a small amount to download the instructions. Modifications are MOCs that are variations on the model itself, that use most of the parts of the set plus some extra ones. Finally, you can use Rebrickable to find inspiration to build MOVs, or My Own Variations, where you try rebuild an existing set or MOC as closely as possible, yet using only the parts from a particlar set.

In the Build chaper of the following review I will show most of these different possibilities, and in next weeks review of set 31088-1 - Deep Sea Creatures, I will show you some others. Please note that both sets are relativily new, they were released only a few month ago, and so the number of Alternate Builds is still somewhat small. Knowing the creativiy of our MOC designers, I have no doubt the number of Alternate Builds will increase significantly in the coming month.

The Set

Get set for supersonic fun with the LEGO Creator 3in1 31086 Futuristic Flyer, featuring an awesome dark red and white color scheme, forward swept wings, tinted cockpit, fixed landing gear and a flaming jet engine. With this LEGO Creator 3in1 set you get 3 different build and play experiences. Build the Futuristic Flyer and then rebuild it into a Futuristic Spaceship toy or a Futuristic LEGO Robot with wings and backpack for more sci-fi fun. [1]

This set is part of series of Creator 3-in-1 sets modeling Jet Aircraft:

The set was designed by John Ho, Senior Play Designer, who has been working at The LEGO Group since June 2013, and who was also responsible, among others, for:

The Box

The box measures 4.5 x 14 x 12 cm and weighs 277 gram. It contains two unnumbered bags with parts and the Build Instructions.

The Instructions

Each model has its own instruction booklet, all measuring 125 x 197 mm:

  • Main Model: Futuristic Flyer (6263523) contains 60 pages and 68 steps.
  • Second Model: Futuristic Spaceship (6263524) contains 40 pages and 37 steps.
  • Third Model: Futuristic Robot (6263525) contains 36 pages and 55 steps.

The pdfs can be downloaded here.

The Parts

The set contains 157 parts and 5 spare parts, in 12 different colors, and 20 different categories, with a total of 65 unique parts/color combinations.

Main colors are:

Main categories are:

The LEGO shop price is €14,99, Brickset list the RRP at US $14.99, but Bricklink offers new sets as low as €11,-. I've got mine for €12,75. Price per part is 9.6 ct (official) or 8,1 ct (discount). The Bricklink Part-Out Value varies from US $18.45 (parts and spares) to US $19.03 (with instructions and box).

The set doesn't contain any new parts, but it does contain two rare colors.

  • 2x Dark Red 33909 - Tile Special 2 x 2 with Only 2 studs
  • 1x Dark Red 47407 - Wedge Plate 4 x 6

The Build


Main Model: Futuristic Flyer

As can be expected from the parts category overview above, that shows that 99 out of the 162 parts are plates or tiles, the build is basically SOT (Stud on Top), and you're just sticking plates and tiles on other plates. The only special techniques are the connection of the tails, parts 6239 - Tail Shuttle, which are placed on two 3937 - Hinge Brick 1 x 2 Base, and wedged against two 85984 - Slope 30° 1 x 2 x 2/3 to prevent rotation; and the connections of the forward swept wings, using a small ball joint connection with 14417 - Plate Special 1 x 2 with 5.9mm Centre Side Ball and 14704 - Plate Special 1 x 2 5.9mm Centre Side Cup, while vertical movement is restricted by protruding plates above and below the wing connection.

Futuristic Flyer measures over 2" (7cm) high, 7" (20cm) long and 8" (22cm) wide. The inventory for this model is the main inventory of the set, you can find it here.

Second Model: Futuristic Spaceship

To see the second model of this set, you need to go to the set page (use the link right above), and select the Alt Builds Tab. Scroll down until you see the heading B-Models. Select the first one, 31086-1-b1 - to see the official LEGO image for the Futuristic Spaceship, and its inventory.

Note: at the moment of writing this review, the inventory for this b-model is still empty. I hope I have some time left during the next few days to add the parts to it, or perhaps, one of our other members will do that.

Futuristic Spaceship measures over 1" (4cm) high, 6" (17cm) long and 5" (14cm) wide.

Third Model: Futuristic Robot

To see the third model of this set, you need to go to the set page (use the link right above), and select the Alt Builds Tab. Scroll down until you see the heading B-Models. Select the second one, 31086-1-b2 - to see the official LEGO image for the Futuristic Robot, and its inventory.

Note: at the moment of writing this review, the inventory for this b-model is still empty. I hope I have some time left during the next few days to add the parts to it, or perhaps, one of our other members will do that.

Futuristic Robot stands over 3" (10cm) high.

Alternate Builds

If you selected the Alt Builds Tab on the main set page, you might have noticed it starts with an Alternate Builds (MOCs) heading. Usually sets like this generate much interest with MOC designers, and after a few month, several alternate builds should have been added. In this case, however, there wasn't that much interest. But have no fear, one of our younger Master Builders decided to go on a building spree while taking a journey through the empty cold of space onto the dangerous and forbidden planet of Gorg... and upon his return, this Master Builder decided to share his creations with all of us.

Wesley (age 4 1/2) was disappointed that there were no alternate builds for this set, so he invented three of his own. They can all be built simultaneously. [2]

Well done, Young Master Wesley! Keep on building!


As the models of this are single models, this set does not contain any sub-sets or LIBs. In my review of next week I will show you a set that has a few sub-sets.


There is also a Modification available, MOC-21136 - Sukhoi Su-47 "Berkhut", but the photos the designer uploaded are all watermarked in such a way, that you can't really see all the details. It seems a bit overdone, for a 145 part MOC, especially because it is a free MOC. And the Studio file is not available, just a PDF generated with Studio, so I couldn't render the model itself. If you do want to see the MOC, just click on the link, but I'm not going to show crippled photos of it.


The main idea of MOVs (My Own Variations) is that you can use an existing set or MOC and try to rebuild it using a small selections of parts, which will force you to consider both color changes and part replacements. You might see a blue and orange plane, such as set 609-1 - Aeroplane and obviously, this set doesn't contain any Blue or Orange parts. So why not rebuild something like in White and Dark Red? Also, there are lots of ways in which certain parts can be replaced with other parts, without changing much to the model. The obvious example is a 3623 - Plate 1 x 3 that doesn't occur in this set, but it can usually be replaced with a combination of a 3024 - Plate 1 x 1 and a 3023 - Plate 1 x 2.

To get inspiration for your MOVs you start by searching the Rebrickable sets or MOCs for certain keywords. For example, click the Search Button in the Main Menu, type "plane" in the text field, select Sets and press the Looking Glass: you will see around 200 sets, most of which models of planes, that you might like to try out. Another possibility is using the Build system:

  • Select the Build Main Menu Option
  • Deselect your sets and parts
  • Enter 31086-1 as Extra Set 1
  • Press Change Build Option
  • Set Part Color Sensitivity to Ignore
  • Do NOT ignore Printed Parts, Molds Variations and Alternate Parts
  • Do NOT Exclude minifigs and non-buildable parts
  • Do NOT include Accessory Sets
  • Press Find Sets You Can Build

Most of the results will have match % less then 100% percent, but that is NOT important in this case. The important issue is that the system show the smaller sets first, which increases your chance to be able to create a variation. If you see some model you like, just press the Build and study the missing parts. Does you set contain similar parts in a different color? Or a different part that looks quite similar to one you're missing? Can you combine some part you have to create a replacement? Why not try to build it anyway, and see how far you come?

I am absolutely no designer, and yet, in a few spare hours, I created the my own variations:


In this basic review I have tried to show that even a simple and affordable set like this Futuristic Flyer can enable dozens of hours of building, especially when you become part of the Rebrickable community. To my knowledge, no other website in the world can offer you this combination of official LEGO sets, b-models and sub-sets, and MOCs and Modifications; and everything I have shown you is freely available, you don't even have to register as a member. If you have any questions, please use the comments, or become a member of our Forum. Please note that the main website and the Forum have their own registration system, so you can choose yourself whether to become a member of the first, the latter, or both.

A final thought.

Half a century ago, when I started to learn how to read, I remember vividly that the first few weeks, I was reading single letters. Then, the next few month, I started reading simple words, and after a year or so, I could read complete long words instantly. Being an avid reader, after another few years, I realized I was reading short sentences asif they were single words, and nowadays, it feels like I read an entire sentence at once. So you're not just getting better with reading when you practice a lot, you actually move to an entirely different level, which couldn't even be imagined when you first started to read those first letters.

I think building by instruction works exactly the same. A few years ago, when I got back into LEGO, I used to look at the parts list of each step, carefully select all the parts I needed for that step, and then, one by one, look-up the parts in the build image and click them in place. The single pieces are like letters, and I building by single pieces. But nowadays, I just glance at the parts list, take a quick look at the build image, then I pick up all the parts I need, and I know exactly where to place them. I think I have now moved to full words, and I am building by steps. This makes me wonder what will happen if I keep practicing. Will I ever just glance at a model and then simply build it, without even looking at the instructions? Is that what it is like to be a Master Builder? I think I've said enough: time to build! -smile-

Take care,

    Good review, and thanks for all the info. I used to buy these smaller 3in1 models when on sale to get cheap parts, but now I have found Rebrickable (and read this article) I can now see them in a different light. Might have to pull out some of my instructions and see what happens. Thanks :)
