Since the LEGO Technic website got its last transformation, it is not providing an RSS feed for its own blog.
Hence it has not been as easy as before to follow the sporadic posts published there, by the LEGO Technic Designers team, or to notice them shortly after their publication.
This is the reason why it took me a couple of weeks to notice the latest posts, where LEGO Technic designer Markus Kossman writes about the design process followed with the 2013 flagship, the huge 42009 Mobile Crane MK II.
Across two excellent articles, he give us an overview of the process, the requirements, the difficulties arisen, the way they were overcome, some exclusive images from design studies and much more.
Nothing that I had not already guessed before, but it was interesting to read in first hand the real motivation/need behind the design of the newest Technic 3x11 curved panels.

Have a great reading!
