Based on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.

How we estimate times · sources and method

Legs, body and small articulated elements need symmetry checks. The estimate also covers the human vehicle. Editorial planning ranges are roughly 65–145%, not measured averages or guaranteed limits.

Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.

Inside the set

Legs rather than undercarriages

Slender supports create an organic shape, distinct from the human vehicles’ wheeled chassis.

A separate human vehicle

The small white-and-blue vehicle is a separate build and counts towards the complete set’s building time.
