Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS). As of September 2008, Lego engineers use the NX CAD/CAM/CAE PLM software suite to model the elements. The software allows the parts to be optimised by way of mould flow and stress analysis. Prototype moulds are sometimes built before the design is committed to mass production. The ABS plastic is heated to 232 °C (450 °F) until it reaches a dough-like consistency. It is then injected into the moulds at pressures between 25 and 150 tonnes, and takes approximately 15 seconds to cool. The moulds are permitted a tolerance of up to twenty micrometres, to ensure the bricks remain connected. Human inspectors check the output of the moulds, to eliminate significant variations in colour or thickness. According to the Lego Group, about eighteen bricks out of every million fail to meet the standard required. Lego factories recycle all but about 1 percent of their plastic waste from the manufacturing process. If the plastic cannot be re-used in Lego bricks, it is processed and sold on to industries that can make use of it. Lego has a self-imposed 2030 deadline to find a more eco-friendly alternative to the ABS plastic it currently uses in its bricks.
Structurally, the plane model is sound and very well-built. A little too well-built in some areas you would say, but they are necessary measures like the awkward humps in the interior of the plane you will discover. Space is very wisely used in this model as they’ve managed to fit a proper looking cockpit for 2 pilots and even managed to squeeze in a sink, a mini-bar with the one drink, seats for 6 more passengers and even a tight little space of a washroom. That door hinge though, is a work of art.
@DrDave : My thoughts were not that the hangar should be big enough to hold *all* aircraft simultaneously - which would, indeed, make it huge! - but that it should at least be big enough to hold any one of them. Just a few studs wider should cover the wingspan of either jet (judging from the photos). Add a few centimetres to the height - by whatever construction means - and that'll accommodate the oversized tail on the Viggen-styled plane. If/when I pick up this set, that's the mods I'll be making to it.
Last to be assembled is the hangar, which given its size is a surprisingly quick build – even though I’m a notoriously slow builder it took me barely ten minutes to put it together. The first step involves stacking dark bluish grey and orange plates and tiles to create a three-sided enclosure covering an area of 24 x 32 studs. Two side walls are then constructed from 1 x 6 x 5 rectangular girders topped off with dark bluish grey bricks and orange tiles, after which the roof is assembled, predominantly from a few large plates including a black 8 x 16 plate only previously available in two sets, and four dark bluish grey 6 x 24 plates which are only appearing in a set for the second time ever. A couple of stickers at the front of the structure identify it as an Airshow Hanger; to be frank, describing it as a hanger is probably exaggerating the case a bit as with its open front and rear it’s more akin to a large shelter.
MPDCenter, developed by Michael Heidemann, helps you to maintain all your MPD files. You can check for OMR conformity (only formal not the layout itself of course). You can extract models with all depending files. Change Author, License, Keywords, Theme, History and Filetype (LDRAW_ORG line) on the fly for all LDR files in the MPD. MPDCenter is part of the AIOI - LDraw All-In-One-Installer.
The cockpit, including the stickers on the sides and the canopy, is identical to that of the first jet, as is the front of the aircraft. As previously noted, however, the wing configuration is different, as is the tail design which features twin tail fins and a pair of fuselage-mounted tailplanes. The red 4 x 1 x 3 tail fins, which have appeared in a total of seven sets including this one, are angled outwards similar to the arrangement on an F/A-18 Hornet. Overall, it’s another sleek design but once again the smooth lines are somewhat spoiled by the prominent canopy.
Attention then shifts to construction of the three aircraft. When I first spied this set I assumed that the two red jets were the same, but closer examination reveals a number of differences. First up is a red jet with a canard wing configuration as seen in the Saab Viggen amongst others. The lower fuselage is fashioned from a number of double and triple inverted 45 degree slopes with a pair of 1 x 14 Technic bricks running through the centre; there’s no obvious reason for Technic bricks to be used in this situation – standard 1 x 14 bricks would have done the job just as well - so I assume that LEGO just happened to have a bunch of them lying around…. A printed black 1 x 2 tile in the cockpit represents the instrument panel, while a substantial air intake is attached on either side of the fuselage at a 90 degree angle by way of brackets.
LDStructure, developed by Michael Heidemann, is a tool for analyzing ldraw parts library. With LDStructure you will get a tool that tells you which parts are required to show the current part and where the current part is used in. You will get this information within a second or even quicker. So this tool is a "needs to have" if you are working on parts for the ldraw part library.
@josekalel: I think the size of the terminal is kept in check for price reasons more than anything. This is a $100 set, and while bigger and pricier City sets exist, they tend to be few in number. What's more, the disadvantage to having a plane wide enough to seat two rows of passengers is that it inevitably takes up a big portion of the budget even for a larger set like this one. If the set were just the airport with no plane, then the terminal could probably be around twice this size at the very least… but then the set would not offer such a complete play experience.
In contrast to the first jet with its delta wing configuration and forward canard wings, the second jet features a more conventional straight wing configuration with tapered leading and trailing edges. As you might expect, construction of the fuselage of the second jet is in many ways similar to that of the first, although in order to accommodate twin exhausts the rear isn’t tapered, and the air intakes which flank the fuselage are of a different design.
The set has an impressive assortment of minifigures - I quite like that it has six, allowing for a lot of play opportunities. All the major parts of the plane - the wing, cockpit, tail and body - are new to this set in their colours. The inside of the plane has a minimal amount of details, with five seats, a galley and a lavatory. The outside of the plane looks quite smart with all the stickers applied.
