Age
Age recommendations are rather conditional, but it is still not recommended to deviate from them. So, building blocks for older children may contain small parts that a curious little child can swallow. At the same time, sets for little ones are easy to assemble and uninteresting for adult children. And an age-appropriate construction set can be too complicated and uncomfortable, upset or even scare the baby.
Note that the age category to some extent also characterizes the maximum age at which the constructor can be useful. For example, a set for
1+ and
2+ is unlikely to attract an
8-year-old or even a
7-year-old elementary school student, and a complex design of
14+,
16+ and even
18+ often turns out to be interesting even for adults over 30 and even over 40. However, even within the same age category, much depends on the characteristics of a particular set, in particular, on the type of game. And there are options for designers for any age. In addition to those listed above, there are also
3+,
4+,
5+,
6+,
9+,
10+,
11+,
12+.
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.
Models in assembly
The number of models that can be assembled from this kit according to the instructions. For example, if a helicopter, truck or boat can be assembled from a set, 3 models will be indicated in this paragraph. Most modern designers are designed for just
one model, quite often there are sets of
2 – 3 and
4 – 10 options, and in the most extensive sets this number can be
10 or more. Of course, a young inventor may not be limited to instructions and come up with his own assembly options; however, the most perfect and functional are usually the models that were originally provided for by the instructions.
Note that kits that allow multiple assembly options usually do not allow you to assemble more than one model at a time — that is, you can assemble a new model only by disassembling the previous one. However, there are exceptions to this rule — mainly among extensive sets of 5 or more options.
Inertial motion
The possibility of movement of the assembled model in an inertial way.
In such models, the wheels are connected to a spring or other similar device capable of storing mechanical energy. To start, you need to pull the structure back so that the wheels turn, "charging" the spring. After that, it is enough to release the model — and the spring will spin the wheels, allowing you to drive a certain distance.
Inertial "motors" are simple, inexpensive, and can be quite fast. However their “charge” lasts less than a few seconds, but this cannot be called a serious drawback — launching inertial models can be quite fun.
