As I found out commenting a recent review of the 10221, the model is a somewhat a controversial subject on this forum. To say that some people dislike it would probably be an understatement
But, despite all its flaws, I have found myself drawn to the model – perhaps because I like modding so much - and the 10221 indeed begs for modding.
Thus I planned to mod the model even before I had bought it. The result of the initial mod (Mod Mk 1) can be seen here.
I thought all was good in the world, but then one day I met a guy who goes by the name ‘Aeroeza’
We lengthily discussed the angles of the 10221 and how the model could be improved/rebuilt further. Aeroeza ended up making a 3D render based on the studio model to determine its angles and proportions.

AT 17,6km in length the Executor is about 5,94km wide. The hull is surprisingly flat… :D
We quickly discovered that some aspects of the model were not feasible in Lego. As also mentioned in another thread by Anio, the overall width of the ship will either be too wide or too narrow using existing Lego wedge bricks – unless you do a voxel model…
Thus using the render as a strict blueprint quickly proved nonsensical. But I could use it as inspiration. So, with Aeroeza’s work, together with a few hi-res photos of the studio model at hand, I made the following “wish list” for (further) modding:
- Extend tail a bit
- Extend the city a bit
- Lower the “city”
- Lower the angle of the top hull
- Remove the fake bridge – and the minifigs :)
- Lower the engine section – middle and back engines
- Lift the middle engines a bit to be in line with the back engines
- More detail on the engine section – next to the middle engines and the back engines’ “support struts”
- Redo and tilt the prong between the forward/lower engines (part of the bottom)
- Remove the flat bottom
- Extend the tip of the A-frame – needed after removing the flat bottom
- Create a new bottom and attach it using hinges (hopefully)
- Tilt the forward (lower) engines to slope with the new bottom/prong
- “Move” the hangar bay forward – to be more in line with the studio model
- (keep most Mk 1 modification intact – besides the stepped plate bottom)
I began from the “top” by removing the city and the fake bridge.

I removed the sloped tips of the structural “ribs” and some of the plating beneath the city. My initial plan was to remove some of the top spine and place it underneath - but that wouldn’t have solved the problem just “moved” it. I discovered that by simply removing or adding plates I could lower much of the city and engine section.
Now that everything had been lowered I could begin testing my solution for applying the bottom. My idea was simply to use the old “hinge-trick” - to go from studs-on-top to studs pointing down. Furthermore the hinges would also facilitate the slight sloping of the bottom plates. My only problem was that I didn’t want to apply the new bottom to the old – but if I removed the old bottom I wasn’t sure there was anything left to hinge on to. Well, I just had to follow Yoda and simply just ‘do’:

Removing the bottom… and

Voila! Seems someone already prepared the A-frame for hinges… hmmm… makes you think…
I quickly fashioned a test plate…

... but showing it applied would “spoil” the ending :P
While removing the rest of the bottom I took breaks to dust off my modded ISD - who was feeling a bit jealous …

…and extend the tail of the ship by elongating the top plates three studs worth.

Afterwards I could begin constructing the bottom plates – suffice to say they went through a “few” iterations, but these are the final ones.

The picture below shows how the hinges are applied to the plate. Also, to get the right look, and close a potential gap, I needed one stud more width on each plate. The problem was that it had to be applied to the “center” of the plates – in other words on the “bad” side of the wedge bricks …
Luckily using the “half” hinges – which have hollow studs, I found a feasible way to apply the extra row.

I extended the tip of the A-frame a bit and then I could begin to apply the bottom plates… snap, snap, snap…

I tried to match the sloping with Aeroeza’s render - and it should be pretty close.

Because of the backmost leg of the model, it made sense to construct the bottom prong between the lower engines separately. The challenge was to line up the angle with that of the lower wings.

Having the bottom angled I also needed to angle the lower engines. Looking at the studio model it was apparent that the forward/bottom engines follow the same angle as the bottom itself. Thus I needed a way to slope the engines – but without actually lowing them further. Here is the solution I found:

Using two 1 stud 1 x 2 plates and…

… Applying this hinge to the engines…

...I was able to angle the engines ever so slightly. In the above pic the extra detail I added is also apparent. Since my mod Mk 1, more detail is added next the middle engines and the support struts have been added to the back engines. Both inspired by the studio model.
Well enough talk – now some more pics:



In the pic above it can be seen that the top angle has been lowered a bit.

The slightly longer tail and extended city in focus.

Lastly a profile pic
My problem now is that the only space I have for the model is my windowsill. This means I would never actually get to see the bottom (unless I’m lying on the floor – which actually happens surprisingly often…), but knowing it is there gives me peace of mind.
Finally – and most important, thanks to the magnificent Aeroeza for inspiration and assistance!
So what do you guys think?

The diffence is that the detailing between the center engines now slopes downward to almost meet with the bottom plate - more in line with the real thing thing
