In box
—
RTR (Ready to Run) — the box contains a fully configured and ready-to-run model. Such models are equipped with a battery, a remote control, and a charger.
—
ATR (almost-ready to run). The model is almost completely ready for use, but some of the elements are still missing. The list of missing components can include both a battery and a remote control or charger. All of the above components may be missing at once. Missing parts must be purchased separately. Models in the ATR package are designed for advanced users, this package allows you to choose batteries or controls based on your own needs and requirements.
— PNP. the receiver and transmitter are not included in the package, and often there is no battery. Additionally, the PNP set may not contain control equipment. Radio models in the PNP configuration are designed for professionals who often use individual electronics. Usually, the design of the model itself is collapsible, which significantly increases the maintainability of the product. Many models sold in the PNP configuration are allowed to participate in prestigious exhibitions and competitions.
— K.I.T. For the most part, only body parts are provided in the kit. The kit has a lot in common with the designer, because from such a kit it is possible to assemble various options for the body of the radio model. The KIT package includes neither radio communication mod
...ules, nor control equipment, nor electric motors. That is, the user will have to buy / manufacture all the hardware of the radio-controlled model on their own. Radio models in the KIT package are designed for advanced users. KIT kits are suitable for assembling advanced models, which are often used in prestigious exhibitions and sports competitions.Purpose (class)
—
Tricks. Cars of this class are designed for driving with various tricks, mainly related to acrobatic numbers, jumping and overcoming obstacles. They have off-road type (usually "monster" or truggies, see below), a powerful engine, high ground clearance, large wheels and reinforced suspension.
—
Short-course. Short-course models are off-road vehicles (buggies, truggies, "monsters", see below), specialized for cross-country speed racing. They offer good protection against collisions and jumping shocks, have a heavy-duty construction, a rigid body that covers most of the sensitive parts, and shock absorbers designed for high loads.
—
Drift. Drift competitions on radio-controlled models involve the passage of an asphalt track at maximum speed with the constant use of a controlled skid. Based on this, drift cars must have rear-wheel drive, a rear differential lock, and tyres with a shallow pattern that are harder than most other models. It is worth noting that their appearance can repeat real cars much more accurately than in the case of
ring models.
— Ring. A variety of road-type models (see below), designed to pass flat tracks with a hard surface (like asphalt) for a while. A distinctive feature of most of these machines is a smooth, "licked" body shape to ensure aerodynamics (or to simulate one if the maxim
...um speed is low).
Note that some of the above specializations usually have professional models designed for competitions and serious automodel sports. If the class is not specified, the car most likely belongs to the entry level and has a purely entertainment purpose (although such models can also have quite advanced characteristics).Max. speed
The highest speed that the machine can develop. Usually, this parameter is indicated for certain "perfect conditions": a flat track, high-quality fuel or a full battery charge (depending on the type of engine, see above), etc. Real figures tend to be somewhat lower; however, different models can be compared with each other according to this characteristic.
High maximum speed is important primarily for "racing" cars (ring and short-course, see above); in stunt and drift models, it does not play a decisive role. Also, you should pay attention to the maximum speed values when buying an amateur model for entertainment — here you need to take into account the features of its application. For example, if the machine is intended for a 3-4 year old child as a toy in an apartment, high speed will not be an advantage, but a disadvantage (especially since the cost of the “apparatus” directly depends on its speed).
Battery capacity
The capacity of the battery supplied with the electric motor model (see "Motor"). Indicated only for variants using original batteries (see "Battery type"), measured in ampere-hours: 1 Ah corresponds to the capacity at which the battery is capable of delivering a current of 1 A for 1 hour.
The higher the capacity of the battery, the longer, usually, the “device” is able to work without recharging. However, the practical time of operation on a charge is largely determined by other characteristics of the machine — scale, purpose (see both points above), weight, model and engine power, etc. Therefore, in most cases, this parameter plays a purely reference role, and it is only possible to compare the battery capacity among themselves with machines that do not have any significant differences in other characteristics.
Battery model
The model of the original battery (see "Battery type") for which the machine was designed. Most often, such a battery is supplied with the “apparatus”. Data on the battery model may be needed if it is out of order and needs to be replaced, when looking for a spare battery or when selecting a charger (usually, charging capabilities are already provided in the standard package, but it is possible that a separate device will be required).
