The structure designed to comfortably because the packages are well organized and the 6-parts manual is well constructed. For the second kit but there is no printed manual, which I find a bit steep but at the rather high price! The crane itself sellt is a technical masterpiece and receives in terms of complexity and functionality the full Punktzahll. A bit annoying I found the rather weak engine which properly has to fight with the quite demanding and energy-sapping features of the crane. The movements, such as the extension of the arm to take account of the correspondingly low translation quite a lot of time and taking place in accordance with the slow motion. All in all: A sophisticated and very lifelike object that knows how to seduce you with its functionality and complexity!
