The minimum age for which this radio-controlled model is suitable. These recommendations are rather conditional, but it is still not recommended to deviate from them. "Adult" models 14+ with many adjustments, moving parts and power simply will not be able to master the baby. At the same time, models for the younger age category may not be interesting and boring for older children.
The presence
of a metal gearbox in the design of the tank.
A gearbox is a device responsible for transmitting torque from the engine to the driving wheels of the tank. Usually, the operation of such a device is based on the use of gears. Gearboxes are also called metal, in which the working gears are made of metal. This provides high strength and reliability of the design compared to another popular material — plastic — and allows you to work with high torque values, which is especially important for massive large-scale models. The main disadvantage of metal parts can be called high cost.

Plastic. Plastic caterpillars are lightweight and inexpensive. Usually, these are used in tanks with a plastic case. On the one hand, due to the minimum weight, such tracks do not reduce the battery life of the tank, on the other hand, they have rapid wear of the tracks (track links). But if the plastic tracks are worn out, you can always buy new ones. Additionally, plastic tracks can slip when driving on smooth surfaces: tiles, parquet, and even just painted wooden floors.

Rubber. Rubber tracks make the tank almost silent. Additionally, rubber provides good grip on absolutely any surface, even perfectly smooth. Rubber tracks are used predominantly in plastic-based tanks. The disadvantage of this type of solution can be considered susceptibility to rapid wear. In addition, it is not customary to drive tanks with rubber tracks out into the street, especially for driving on asphalt or primer, carpet, linoleum, parquet, tile and painted wooden floors are more suitable for them.

Metal. Metal tracks provide excellent traction on any outdoor terrain. Metal caterpillars have high strength, they are reliable and durable. Additionally, the clang of metal adds realism to the toy tank. Such caterpillars are primarily characteristic of tanks in a metal case, but in some cases they are placed on tanks in a plastic shell. Metal tracks make the tank heavy, w
...hich affects its battery life. Additionally, this type of solution has a higher price.
