As is the norm with LEGO sets these days, there are a fair few stickers in use for this item. I’m still not a fan of their use, but at this point in time, it is something I have come to expect and just get on with it now. In their defence, they do add to the overall presentation, making it that little bit harder to complain. As I said, this is my favourite of the three planes in the set, mainly because it looks superb and offers a great build experience. Seriously, I had so much fun building this. The instructions – as always – are clear, and it is not going to provide any major issues. Stability-wise, there are no concerns here, with the finished product very sturdy and, as proved by my daughter, can handle itself when being flown around the room by an excited seven-year-old. One minifigure can be seated at the controls, with suitable space for application and removal. The other pilot has its place on the top of the plane, with a single piece of black fencing to provide support for the death-defying pilot.
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.
In December 2012, the BBC's More or Less radio program asked the Open University's engineering department to determine "how many Lego bricks, stacked one on top of the other, it would take for the weight to destroy the bottom brick?" Using a hydraulic testing machine, the engineering department determined the average maximum force a 2×2 Lego brick can stand is 4,240 newtons; since an average 2×2 Lego brick has a mass of 1.152 grams (0.0406 oz), according to their calculations it would take a stack of 375,000 bricks to cause the bottom brick to collapse, which represents a stack 3,591 metres (11,781 ft) in height.
The definitive shape of the Lego bricks, with the inner tubes, was patented by the Lego Group in 1958. Several competitors have attempted to take advantage of Lego's popularity by producing blocks of similar dimensions, and advertising them as being compatible with Lego bricks. In 2002, Lego sued the CoCo Toy Company in Beijing for copyright infringement over its "Coko bricks" product. CoCo was ordered to cease manufacture of the products, publish a formal apology and pay damages. Lego sued the English company Best-Lock Construction Toys in German courts in 2004 and 2009; the Federal Patent Court of Germany denied Lego trademark protection for the shape of its bricks for the latter case. In 2005, the Lego Company sued Canadian company Mega Bloks for trademark violation, but the Supreme Court of Canada upheld Mega Bloks' rights to sell their product. In 2010, the European Court of Justice ruled that the eight-peg design of the original Lego brick "merely performs a technical function [and] cannot be registered as a trademark."
Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.
