I searched and didn't see this one but if it already exists mods please merge.

So I was breaking down my Tumbler, selling it as used, and I was just amazed at the level of complexity to this build. It gave me a new appreciation for some of the different techniques that are used when I was taking it apart

So what were some of your most challenging builds and why? This may help others select their next set or help them avoid one.

My top 3 easiest to hardest:

3. United Nations, after 40 years of not playing with Lego I saw this set at BN and those translucent blue tiles were just calling my name, little did I know what I was getting into. As a kid I just did free building never had sets with instructions so I had no clue what that Arch book was or how to follow them. This was deffinetly not the best set to start off with. Trying to fit my fingers in the tiny interior and do sideways building was a struggle but I loved the finished product, still one of my favorite sets.

2. R2, at the time I built the droid it was my first UCS set and second most number of elements behind FB. This set had some challenging building techniques, getting those columns of 1x1 alternating white and blue tiles perfectly aligned put a hurting on my fingers. The most difficult part of the build for me was the mistake of using the ipad PDF instructions. Not only were there mistakes in them but telling the shades of blue apart on R2's dome was a task

1. The Tumbler, the winner by a landslide. This set gave me fits at times to the point I had to walk away and take a few days off, I don't know how you guys who knock these sets out in a few hours do it. The combination of building at night with poor lighting, my old eyes, and all the black elements made mistakes the norm. There were three times I had to do rebuilds plus parts like to move and fall off of this awesome set. I would highly recommend this set to build. I think I will avoid the ToO knowing that the black elements and I do not get along.

Well I hope this post helps someone and I look forward to your responses, I am hoping there is a good sleeper set out there waiting to be built.

10212 Imperial Shuttle.  Not a difficult build really, but very time consuming.  All of the white starts to blend together after a while, especially when building the wings.  Also, it's a 2500 piece set with no numbered bags, it's the first time I actually took time to sort the pieces before building rather than just dumping them in a pile.  It was also hard to tell the difference between gray, dark gray, and black in the instructions.  I ended up with 2 dark gray 1x4 plates when building the stand at the end, so the correct black ones I needed are buried somewhere in the shuttle.

I think the posts on the older Star Wars sets show just how much better directions have gotten over the last several years.

In terms of print quality the color problems still exist in brand new sets I've bought this year.  Some books are better than others, but it's still a pain to tell the difference between some colors.

 

In terms of the actual steps, I find that the baby steps instructions have get tedious.  There is no reason most of the time to have 2-3 instruction books, especially for the sets aimed for older teens and adults like UCS.

For me this would absolutely be the Taj Mahal. I actually have a couple of these and decided to build the 3 used ones I have. Talking about a repetitive build. But with a great end results. Ended up just changing up the sequencing of the built

It could just be the sets I have built, but Lego seems pretty good about not having the same type of piece in multiple similar colors (grey, dark gray, black).

Let me introduce you to my little friend

Did it also have 2 instruction books?

I hope that one had numbered bags..,
