This was a pretty technical build and I even accidentally did a step wrong near the beginning but didn't effect the rest of the build till I was finished and the lift arm didn't work.  Look through the manual/instructions and right near the beginning first bag I missed putting two cogs on... opps. It also has quite a few stickers which can be quite fiddly to put on... That being said overall I enjoyed this build, but it is a little more complex than you might first realise.
