Number of pieces
The total number of parts included in the delivery of the designer. At the same time, the calculation, usually, also takes into account the details that make up individual characters (torso, arms, legs, head, etc.) — despite the fact that the figures are most often delivered assembled and are not designed for disassembly during normal use . Also note that the kit may include several spare parts, in case of breakage or loss of any of the main elements.
Moving elements (mechanics)
Details and elements that, after assembling the designer, can move, but are not driven by a motor; in other words, moving parts that need to be moved manually. These can be, for example, windows and doors, hatches, screws, crane booms, etc. The exception is rotating wheels — in this case they are not considered moving elements.
Mechanical moving elements can be combined with motorized ones (see below).
Moving elements (motor)
Parts and elements that, after assembling the designer, can move due to
the drive from an electric motor. In the simplest versions of such constructors, the movement is turned on and off using a switch on the model itself, in more advanced ones, remote control with quite extensive capabilities may be provided.
Note that this feature is indicated only if the motor is supplied in the delivery set. Kits that allow the installation of an engine, but are not equipped with it, are not motorized.
