[MOC] Imperial T-4a Lambda Class Shuttle

[Evilkirk]

The ultimate Imperial Shuttle Lego MOC: The Sienar T-4a Lambda Class. 
Two years of meticulous building, design, redesign and re-build - and now she's finally here!

3 different sets of instructions have been prepared for this ship - and every buyer will have access to all 3 models - available on Rebrickable.

The Imperial Lambda Class Shuttle, 5420 parts.

These elegant transports were the workhorse of the Empire; initially used for transporting Imperial officials and officers around the galaxy - and in later days as these shuttles became more common, they were often used as simple troop transports and even light cargo ships. Lord Vader himself was known to use a Lambda Class Shuttle - and this was also the same design as the famous Shuttle Tydirium, which was stolen by the Rebels and used to transport the Endor strike team in Return of the Jedi. 
There are various floor-plans out there for this ship, but I chose the official design which makes most sense to me + it was the layout used in the "Incredible Cross Sections" book which featured this ship. It's as close as I could get it whilst using Lego, although you will have to allow me some 'poetic license' here and there :)

I've also designed an "empty" display version, with no interior and 4817, perfect just for display or modding with your own interior design! ...and then, there's the Emperor's private shuttle, which I'll be posting separately 

There's a choice of 2 display stands for showing the ship in flight mode - both are FREE downloads available on my Rebrickable page.

Lastly, I’d just like to add that personally, this was always more than just a Lego creation.
It's a Lego brick-built replica of what is, to me, the single most elegant and beautiful ship in all of Star Wars. This is something that I've dreamed of making since I was a kid in the 70's - and now it's time to share it with others.

I don't think I have the words to describe just how good this is. This could have been used as a model in the original films and people would not have been able to tell it was lego. The shaping is immaculate, the interior detailing even more so. The small hatch to access the maintenance compartment is a neat addition that really shows off the detail and scale of the model as a whole.

Thank you so much - making it fit the correct amount of minifigures and 'not looking like Lego' were always top priority for me! I'm glad you like it :)

Fantastic job on this! Also kudos to your wife for test building it.

Thanks! ...and yes, it took her 18 hours with no help from me (apart from finding the pieces for each step) split into 3 sessions <3

Absolutely stunning job! I love the stand too, it really complements it. And so many awesome details, well done!

[hazelhorn]

Gorgeous! My favorite detail is the angled panel line you managed to capture in the top wing.

Thanks very much! It really needed a fancy-looking stand :)

 

Thank you!!

DOIN' IT!!

Instructions purchased, first parts order already completed...now to sift through piles of inventory to see what I have and what I need.  My 10212 will also be torn apart soon.  This will take a while...my guess is early Spring for completion.  Building is the easy part - it's the planning, printing, sorting and sourcing that takes all the time.  I can't even imagine all the hours you invested to DESIGN the damn thing!   Forever grateful.

Original fleet shuttle, or Emperor's version? I look forward to seeing it in Spring! 

[lowlead]

I like the executive interior so I'm leaning towards the Emperor's version - with the fancy stand, of course - but I also like small bits of color variation on the stabilizers.  I might ignore the official versions and do a hybrid of the two just cuz I prefer the look.  Surely the Emperor had a spare shuttle or two on hand.

My completion goal is earlier than Spring but work always impedes.  I will double my efforts!

I HOPE SO LOWLEAD, FOR YOUR SAKE. THE EMPEROR IS NOT AS FORGIVING AS I AM!

"...I tell you, this shuttle will be operational as planned."

...Christmas arrived a few days ahead of schedule!

This design is incredible - I'm at a loss for words.  A few interior tweaks to accomplish, more photos to follow....

Ahhhh it makes me so proud to see my builds in other peoples displays and houses! 

I'm really glad you're happy with the finished product + the display stand looks as Imperial as I hoped it would! Impressive, most impressive

"Oh...it's...beautiful!"

EK, I cannot repeat it enough - you have achieved greatness here...right down to the ultra Luxe display stand!  You are among an elite handful of MOC designers who presented a creation that immediately inspired me to begin gathering parts.

In other news, I changed my mind about the interior - I went for the fleet model with aft weapons locker.  Due to a small error in a Bricklink order I'm missing a DBG 1x3x3 door so the 'refresher' currently has no privacy  But the transparent yellow round tile made me laugh!

I'll make a point to post more photos as I go - your design deserves all the press it can get.

Thanks again mate - I was tempted to put the yellow tile on the floor (as stormies tend to miss) but I didn't want to overdo it
