SpaceX Falcon Heavy Block 5 (Saturn V scale) UPDATED




This is a major update to our previous Falcon Heavy Block 5 design. This 1:110 scale is the same as the official Lego Saturn V.
This version contains all the key interesting features of the original. In addition, we updated the colour of the side-booster nose cones, added the black fuel lines on all 3 main cores, and include a stickers! Specifically, it uses these office envelope labels in clear.  (This requires an overnight for the ink to dry if you use an inkjet printer.)

We hope you enjoy building and play with this wonderful and complicated rocket.  I created the instructions using LDraw, Bricksmith, & LPub. Thanks to the creators of those pieces of software!

    Have not yet applied any stickers on the build. Any news update when the SpaceX Letters will be available? I also would take the large falcon logo on the cargo bay. Don´t bother if consistent or not.

      Ok new stickers are in the updated file I just uploaded.  You'll find the vertical SpaceX logo (3x) as well as a huge Falcon logo for the fairing.  Let us know if you run into troubles or want to see further changes.

        I will take a look on it. Unfortunately the instruction file still shows March 2019. Maybe it will take a while until I see the new one.

        Update: Still can not see any new file. It still shows the old one from March

          I just checked the admin page and it shows the the labeled "more stickers" and Oct 2019.  Please check one more time.

            HI guys,
            It took me a time but I had to alter the idea abit. Unfortunately the mentioned avery sticker in not available in the EU but a similar version. as the Letter 4 format is a bit entirely smaller as our A4 format, it wont fit. I searched for the appropriate logos and located them properly on the A4 avery labels. I find it quite good looking.

    Finished it On sunday. Liked it. Unfortunately the instructions do not show the installation of the feet hinges, when the feet are folded Out. They are only shown beside the Rocket. I also found a picture showing the Block v Heavy Center falcon showing also the spacex Letters ans the large heavy Logo in the Cargo halfs in the top..
    Can you provide the missing information ans the additional decals?

      Hi thanks for the comment and your purchase! Glad you liked it. Let's address your two concerns. (1) It sounds like you're having trouble figuring out how the supports attach between the rocket's body and legs.  I will make that update this week; you should be notified when new instructions are available for download.  Thanks for highlighting this omission. (2) You're right that the current design only includes two stickers. The large Falcon Heavy logo on the payload fairing isn't consistent. For example the Arabsat launch had the Arabsat logo on the fairing.  The long SpaceX logo along each booster was tricky - we'll keep working on that and hopefully find a solution.  Thanks again!

        Great thx. To be honest I assume to have the correct Position but i am not Sure If they are attached to the Legs, to give more stability, or If the lower part is only touching the Legs and clamps it by the rockets own weight.

        I also altered the external fuel lines. The Set tells you to use a black hose but i only received curved / deformed ones. So i took some wodden design Sticks from my vase, that are luckily perfect straight and black. The also provide the perfect diameter to match with the clamp bricks.  😂

          There are now 2 photos showing an example of attached landing legs.
          Thank you for the idea on the fuel lines. Someone else mentioned using 3-mm diameter welding rods, which also come in black. Great suggestions!

            Yeah I'd like to see an update to the stickers as well; even if it's just the stickers from the previous model included in this one. The build instructions for the central booster would just need to be changed to align all the curved panels vertically.
            As for the external fuel lines, I had the idea of using automotive electrical cable cut to the right length, as it's the right diameter and has the right appearance. The copper in each end would need to be removed, but that's not hard with a set of wire cutters and pliers.

              Interesting idea for the electrical cable - if you have tried it, does it curve or bend?  Hopefully it stays rigid.
              Regarding the stickers - there is a new version uploaded with vertical SpaceX letters for each booster as well as a bigger Falcon Heavy one for the payload fairing.  Enjoy!
