The programmable Lego brick which is at the heart of these robotics sets has undergone several updates and redesigns, with the latest being called the 'EV3' brick, being sold under the name of Lego Mindstorms EV3. The set includes sensors that detect touch, light, sound and ultrasonic waves, with several others being sold separately, including an RFID reader.[52]
^ Jump up to: a b Alexander, Ruth (3 December 2012). "How tall can a Lego tower get?". BBC News. Archived from the original on 4 December 2012. Retrieved 4 December 2012. The average maximum force the bricks can stand is 4,240N. That's equivalent to a mass of 432 kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000. So, 375,000 bricks towering 3.5 kilometers (2.17 miles) high is what it would take to break a Lego brick.
This was bought for my son's 5th birthday. If your kid likes to really play with the sets like mine does (not just bought for building it) be aware that the door of the airplane likes to pop off if it is not opened/closed just the right way with gentle hands. My son is a typical rambunctious boy and is not great at opening/closing things gingerly, so the door presents a bit of a problem for him. He doesn't have the dexterity or patience to snap the two tiny joint pieces onto the little pole just so yet, so whenever the door comes off he gets frustrated and needs help. Which is fine, we help him and he will eventually learn to do it himself, but just wanted to make y'all aware of this in case you have someone who is picky about the door opening and closing easily/correctly :) I know some little ones get fussy about these things!

The rest of the model is pretty standard for a Marvel release. Most of the larger sets revolve around a vehicle and/or small structure. This one doesn’t disappoint in that respect. First up, you get the airport control tower. It’s fairly uninteresting, although they have added an exploding wall-play feature which kinda makes up for it. Otherwise, though, it’s simply a tower. In addition to that you get a small baggage car, which is pretty neat. In fairness, as cute as it is, it feels like an attempt to bump up the number of pieces. Lastly, the set comes with a Quinjet. This particular vehicle is considerably smaller than the previous two minifigure-scale Quinjets that Lego gave us last year and in 2012. That said, it’s a great model with some great features.

@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.
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.
Colour-wise, it is mainly yellow, with only a dash of green and red, and a little more white, there to break it up. The worker has space to stand and drive the vehicle, and has a walkie talkie attached on the side of the car. Around the other side is a coiled-up, what I assume is a, fuel pump. It looks pretty good when coiled up on the side of the car. Stickers come into use again here, this time for the number plates.
