Mould King21009 Technology Remote Controlled Sand Crawler Model, 13168 Pieces 2.4G/App RC Sand Crawler UCS MOC Kit Sandcrawler with Full Interior Large Collection for Space Star

This build is truly impressive, even to those who aren't Lego or Star Wars fans! I really enjoyed the build and had it done in about 2 weeks. Nothing was too complicated or anything, a rather straight forward build with lots and lots of pieces... so many pieces. Buuuuut...Why only 4 out of 5 stars? Well for starters, and probably my biggest gripe: The instructions. They are hard to read. The shade of brown ink used for the instructions makes it almost impossible (except in the best lighting) to see what bricks go where because I couldn't differentiate between the brown bricks and the lines separating them. This makes building some parts where there's many small pieces lining up end to end hard to figure out where they belong. Many times I had to turn on my phone's flashlight and stick my face right up to the book to see where the pieces actually belong in a given step. Is it a deal breaker? Nah. Is it annoying? Very. Also in the instructions at the start it has you letter the motors with stickers. When you are putting in the motors for the track pods it doesn't tell you what motors go where as the picture of the motors lacks the lettered stickers. You will need to skip ahead several steps to see which ones actually go where.My second (and I guess small) gripe: So this MOC is... let's say "inspired" by someone else's. Well all the white on Mould King's is light bluish grey on someone else's MOC. I disliked the look of the white enough (because white isn't very Tatooine, is it?) and I went and bought all the pieces in light bluish grey that are visible in white on MK's model and, honestly, makes the model look much better in my opinon. This cost me about an extra $125 in buying the parts. Is it necessary to buy the parts in light bluish grey? No. Will the Sandcrawler look better for it? In my opinion no one asked for, yes.I made several modifications to the model's front panels so they align better. The picture used on the Amazon listing is not how the panels align in the instructions you will get. They don't droop over one another. However they don't align perfectly and won't look like the pictures I posted if you follow the instructions. If you Google "Mould King Sandcrawler Modification" and follow the Reddit link, a user posted a very helpful guide on how to make all the front panels line up better and avoid gaps. You will need extra parts however to make that work so Bricklink will be your friend.All in all I am very happy with the model and glad I bought it. It now and forever will be the center on my ever growing Lego and "Not Lego" collection. The model is sturdy and the bricks feel like they fit more snugly to one another than Lego's bricks do. I'd highly recommend this to anyone who has the time, money, and the fingertip fortitude to put 13k bricks together!

You can always tell the quality of a company by how they address problems. My set was missing an entire bag of parts (bag 19 missing, bag 31 duplicated). I reached out to Mould King via the Amazon App and received a response within a few hours. They graciously offered to ship me the replacement bag directly. I could not have been happier with the transaction.The set itself is a beautiful MOC, meticulously reproduced from CaveGod’s original. Instructions are well designed; colorful, easy to read, beautiful pit together in two bound volumes. Pieces fit together perfectly, comparable to Lego (and interchangeable with Lego). I opted to replace all white pieces with gray and dark gray to give it a more natural feel and my back stock of Lego blended seemlessly.Very happy with all aspects of the set and as a result of this transaction and the quality of the product I just today purchased another Mould King set (the Rollercoaster one). My third Mould King set so far and definitely not my last.(Note: My Crawler has been modified from the instructions to make the front panels properly mesh, and I created the Spec Plate. Additionally, I replaced all white plates with dark or blueish gray plates to give it a more worn-in look)Well done guys!

Those measurements weren't exaggerating, the set truly is a beast.For the price, it's pretty close to a great deal, perhaps if it was an extra $100 cheaper since most of the pieces were a variety of common 1x2 flat pieces and 1x1 single bricks.I have built many sets, and so far this one took the longest, almost 2 weeks (and not just 1-2 hrs a day, I mean almost 7+ hrs a day). Make sure you buy a few packs of super glue, sets of these size and weight/density/etc. don't have good self stability, many areas broke apart from the slightest stress. It truly is a crawler since it goes at about 2 feet per minute, can't blame it since the set is around 40lbs.The reason for the 4 instead of 5 star rating was like the other reviewers, the instruction booklets are truly difficult to tell the different shades of brown apart. I had to use my phone and take several pictures from different angles of lighting to compare and see if it's the same shade or a darker one, and to separate the flat gray from the gloss gray, all they did was add a tiny sparkle symbol on the image piece... which isn't mentioned and I didn't notice until many steps have passed. The final parts were very difficult to clamp together, in fact some would not bend or reach the joints, so modifications had to be made to make the set presentable. The surprising part was that the set barely missed any pieces. For a set of over 13k pieces, I was only missing 2-4 common pieces, not bad.

Although this is a beautiful and huge kit, the instructions are flawed in several places. The last steps of installing the front panels are particularly bad. Also, the dark brown printing in the manuals makes it extremely hard to discern the stud counts etc... Overall, very nice, but needed some major modifications to make everything line up at the end.

Can’t give too detailed a review since it’s not been opened yet due to it being a Christmas present. But based on a few videos I’ve seen, it’s awesome.

40 lbs of awesomeness, Instructions are easy to follow packaging is well marked, I can't wait to show it to my friends and family. I will be a repeat customer. Very professional Thank you.
