Giant Cargo Aircraft C-3 X (old WIP)
Check out some photos of a truely ambitious, but unfinished project!
About this creation
Note:
The production of the C-3 X came to a halt a long time ago. Due to unsatisfactory and old design features, its enormous size and me not having enough parts to build the aircraft how I want it to be back in 2009, it has been dismantled since quite a while.

Various other aircraft, including cargo types, are on my building schedule.


























Like on the title picture, the next ones show the aircraft with fully outdriven air brakes. Note how there are some on top and underneath the wings:













As you can see, the tail rudder was supposed to become fully finctional. Its side rudder, subdivided into two movable sections, was all ready to go...





I used to really like the curves of the nose cone, as well as the entire front section almost. Looking at it now would make me want to rebuild it. Especially when seen from the side, the nose's shape is still too "rough", not smooth enough...



















Here´s a close-up view of the cockpit interior:



The retractable stairs:









And a bird's-eye perspective...





Some mobile stairs I made for standart aircraft. Their height can be adapted to different levels for different fuselages:









And finally, some size-wise comparison to my F-90 fighter jet:













To the dimensions:

Length: ca. 108cm
Wingspan: ca. 113cm
Horizontal diameter of fuselage: 16 studs
Width of cargo hold (front section): 10 studs on the ground (+ 4 studs on a higher level)
Width of cargo hold (rear section): 10 (+2) studs - I was planning make it wider in the back so even larger vehicles would fit in...
Loading options: One giant rear ramp & 2 side ramps (drivable with small vehicles)

Thanks for visiting guys!
Best regards,
Steffen

This is great... maybe you'll build the antonov an-225 one day??? i know i would if i had enough bricks 32 tires for landing gear... 6 massive engines. i imagine the cargo area would have to be atleast 16 studs wide. probably 20 would be more realistic though so it could easily fit 2 6-wide vehicles inside. anyway awesome plane i am looking forward to seeing it done and loaded up with cargo

It convincingly conveys that burly, beastly feel of large cargo planes. I don't think there is a problem about not finishing it. There are plenty of real world projects that get canceled too. This MOC could just be thought of as being about one of them. Love the flaps above and below the wings.

Hey Tony, thank you! I'm glad you like it. The nose is a question of taste. I´m gonna adapt at least the very tip of it. In general, I like it rather pointy, though. Just looks more interesting to me. And I admit I don´t really know how to imitate a really round nose cone yet... Steffen

I will be pleased if I can thanks.
Of course you can borrow ideas - if I wanted to keep secrets I wouldn´t post stuff here:)= And you know, if you think it´s something special - just say where you saw it - at least that´s what I always do when I borrow ideas from other builders. 12-studs-wide fuselage sounds nice - that´s a good size for a larger Lego aircraft IMO. After the C-3, I might make some smaller plane again, too - to substitute the C-2 which will be dismantled in the nearer future:)... Can´t wait to build again, but I´m gonna keep up the Lego time-out til December. Then, if everything goes well during the next couple of weeks, I´ll have my Master`s Degree and be mostly free until I find a real job. Now, I just have a student job.) Steffen

Didn´t you see the pics further below, Kade? For the most part, the fuselage still needs to be built. Also, the tail rudder (rudder of height/altitude control) needs to be integrated. Then the landing gear might undergo some changes... No,no, it´ll still take some time. Best regards, Steffen

Quoting Kade Groh Quote me please steffen but is this a comparison with the C-5 or An-225 mirya or the russel? anyway can you tell me where I can get the plane elements for my cargo's? pick a brick brickshelf? please answer this I will be please and answer the comparison too -kade- P.S. nice aircraft I will comment them later.
Hey Kade! Thank you for the nice comment! It´s loosely based on a couple of my favorite cargo aircraft and incorporates some of my favorite feautures of all of them: Ilyushin Il-76, Antonov An-124, Boeing McDonnell Douglas C-17. I wanted the nose to be rather pointy like on some Russian aircraft, high wings and a T-tail as well as a low lying fuselage. Some larger windows in the cockpit for better visibility, etc. What makes the plane different from all the above (real) aircraft is the angle of the wings: They´re only slightly backswept, which results in increased lift and a little slower airspeeds... But speed is less important than lift capacities, which is why I went for the current wing design. I´ll maybe remodel parts of the aircraft a tad, too. To the pieces: I have a big collection from my childhood of which I benefit a lot. I sometimes buy little sets, order pieces online or go to a Pick-a-Brick store to accomplish the collection. You can also order from Lego directly online - cause in the stores, they often don´t have what one currently needs... Steffen P.S.: Have you checked out the C-2 already? You might like it as well.

Quoting Kenneth Millar Awesome! Can you make an airliner next time please? :)
Hi Kenneth, I´m a huge fan of cargo aircraft. They look much more special and appealing to me than airliners. So I´ll rather make cargo planes in the future as well I guess. Another reason which adds to it, too: playability is just much better if you have a huge ramp in the belly of the plane (driving vehicles like trucks etc. in and out is so much fun!:):)) And I like to play as well:):):) I might use the standart Lego 8-wide fuselage parts for a smaller passenger aircraft, though!

Thank you! I know, I love cargo planes, too! They are so awesome, and everytime I see one at work, I´m utterly excited:). The nose and cockpit section was actually a lot of work and difficult to work out, mainly because of the SNOT work on the the lower front fuselage and the retractable and securable/fixable front landing gear (there´s a retractable strut going through it [right behind the gear´s main strut] that can fix it - I´ll show the openable "playability"-shaft of the support strut later on the finished model). It was quite hard to figure out and the gear is a bit tricky to get out again after you retracted it, but it works.

Hi Josh:), how are you doing? Thank you for your very kind comment! I know, I havn´t been very active here recently other than writing a few comments every now and then... It´s because of my "Magisterarbeit", which is the old German equivalent to a Master's Thesis in English speaking countries. I´ll have time until June 15th to finish it, so I decided to not build anymore until after that. I really miss building though, it´s very hard to see the giant plane over here on the table and not continue... I´m sorry, I´m really bad with MSN... I usually don´t go online there cause once I start, it´s hard to stop chatting with friends... BTW, have you changed just your name or the entire account on MOCpages?

Hey, thank you very much Michael! I think it´s mainly my English that makes it a bit confusing and hard to understand... If you could show me some pictures that describe what you mean- that would be awesome! I know a little bit how some real ones work, but doing it in Legos seems kinda hard since you´d have to compress so many special technic pieces in a small space(I think each single pair of wheels of an Antonov-124 turns and then folds in... - quite complex stuff). Of course I could just build it so it looks neat while standing, but I want it to really retract somehow... To the nose: I kinda like it like that, but just to have an alternative I might build one out of thin plates etc.- I guess that´s what you and Ralph meant? I don´t want to make the entire nose pointier anymore - I like it and it was actually a lot of work to shape it like that and integrate the working front gear. The main gear is the hardest thing for me I must admit. Thanks again for all the advice! Talk to you soon, Steffen

Wow. Beauty and the Beast all rolled into one. A few critisisms - I'm not completely sold on the very tip of the nose. If it was me I'd either try and make the entire nose a little more pointy, or round the very tip. As for landing gear, a look at the main gear on Spencer R's Space Shuttle Discovery might be handy. One point that might be helpful to know: A lot of our landing gear isn't so 'retractable' as it looks, its more 'dismantleable' and 'hinged' simultaneously. I usually have an accurately-hinged main strut, and a support strut that detatches and tucks away to hold it in place when the gear's down. So it's like this: |/ The first strut is hinged accurately, the second detatches and folds independently. Don't know if that helps, or if it just makes everything more confusing... maybe I should take a few shots of what I mean and post 'em somewhere... All-in-all, this is an awesome and ambitious build that seems to be coming along quite nicely. I'll be looking forward to the finished result!

Hey Steffen! I agree with most of the other comments that this is shaping up to be your best creation yet! I love all of the functionality, it gives it a really nice sense of realism and detail. Speaking of detail, there is so much for such a large aircraft. I don't know how you managed to make it this large, knowing your lack of pieces. I don't think I even have enough white bricks to build just the wings or the bottom of the fuselage! The look from the front makes it very intimidating and the size of the engines just makes it seem even more powerful. Congratulations on all the positive feedback you've gotten, and good luck with the rest of it! Talk to you later - Jeffery Smith

Thank you Jeffery:) Half a year ago, I coudn´t have built this plane how I´m doing it right now. Briefly before last Christmas, I got my brother's Lego collection for 200 Euros - he didn´t care anymore. So my collection was all of a sudden enlarged quite a bit:) It is true though: an aircraft of that size is incredibly part-consuming. I´m gonna come up with a cool black&white color pattern so I don´t have to build it "all white": I think would have enough white normal bricks for the fuselage, but the thin pieces have almost all been used for the giant wing... I have a small box with some more white thin pieces, the white "Heavy Hauler" I could dismantle as well as the mixed-colored yellow and white semi&trailer. Other than that - that´s it (I don´t want to dismantle the C-2 yet). Don´t know if it´ll be enough, so I was already thinking of a cool black&white scheme:)... That should be fine then.

  March 20, 2009
Hey Ralph, thanks a lot for your advice! Those windows, I must admit I really like them. I could maybe try out a different design of the radome built with little plates - that would make it a tad "studier" but could look nice. To the main landing gear: Adding maybe 1 or 2 of these wheels might work, to give it the look you mentioned. Bigger wheels - hmm - I don´t know how to integrate them well in the fuselage. Even those little ones need an enlargement of the fuselage in width that is quite considerable... The problem here is that I wanted the fuselage to sit rather low. And I must admit that I don´t really know how to make better landing gear that folds in differently (mine would just folds in to the side and closes its "cage" from the side. How do you get wheels (especially bigger wheels) folded into a smaller "cage" and still keep it stable (cause the weight will be quite considerable later)? Landing gear is always the biggest problem for me. And then, the fuselage held low for the unconventional side ramps also makes it somewhat hard to integrate functional landing gear. I wish you could actually help me there. Steffen

By the way, the aircraft is loosely based on some of my favorite real cargo jets, of which the Ilyushin Il-76, Antonov An-124 and the Boeing C-17 can be mentioned as rather influencial for this creation. The C-3 here doesn´t exactly look like anyone of them, but incorporates my favorite features of all of them. For instance, I wanted the nose to look "Russian" in terms of engineering - pointy and longer than on most Western aircraft...
