Just a note to say that this is a lovely scale model with some great parts and technical details. However whilst I love the new linear actuators (i.e. 'hydralics'), because they are unlubricated (for reasons I can work out), they fail to deliver any force when under any load (even when load is in same direction of travel). Enjoyable, and lego is as great as it's ever been, but ultimately this is just short of five stars because it's too weedy to deliver what it visually promises. I have to say this is true of most current lego sets - look great, nice build and parts, but is not as solid as the old-skool way of building with regular bricks.
