Comparison Meizhi Bugatti Veyron 1:14 vs Meizhi Hummer H2 1:24

The scale allows you to estimate the overall dimensions of the model — it describes the ratio of its dimensions to the dimensions of a full-size machine of a similar type (see below). For example, the length and width of a full-sized buggy average about 4 m and 2 m, respectively; this means that for a radio-controlled model on a scale of 1:10, these parameters will be 10 times smaller — about 40 cm and 20 cm (plus or minus).

Miniature scales are considered to be 1:24 or less ( 1:28 and 1:32), while in the largest scales it reaches 1:6( 1:5) — such models are not much smaller than children's cars (however, they are not intended to replace them). A small size is considered optimal for use in residential areas, a large one — in open areas. Most road models (see 'Type') are available in 1:10 scale, SUVs in 1:8, and larger scales are found in advanced internal combustion engine models (see 'Engine'). The most common scale options are 1:14, 1:16 and 1:18, which are found in both the low-cost and high-end segments.

— 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).

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).

The type of power source used in a machine with an electric motor (see “Motor”).

- AA. Replaceable elements of a standard size, popularly known as “pen-light batteries”. The main advantage of battery-powered cars over battery-powered cars is the ability to quickly replace dead batteries. On the other hand, the power of such power supply is quite modest, so they are found mainly in models for younger people.

- AAA. Such elements are almost completely similar to the AA described above and outwardly differ from them only in their reduced size (which is reflected in their common name - “little finger”).

- Ni-Mh. Specialized batteries made using nickel-metal hydride technology like other batteries ( Li-Pol, Li-Ion, Ni-Cd, LiFePO4, branded) are superior to replacement batteries in capacity and compactness and are better suited for powerful electric motors. Ni-Mh batteries themselves are notable primarily for their ability to withstand high charge and discharge currents without consequences - the first is important given the “gluttony” of electric motors, the second has a positive effect on the charging speed. In addition, such batteries are resistant to low temperatures, do not h...ave a “memory effect”, and are relatively inexpensive. At the same time, they are inferior to Li-Pol elements in terms of capacity (with the same dimensions).

- Li-Pol. Specialized batteries made using lithium-polymer technology. For more information on specialized batteries in general, see above (Ni-Mh). Li-Pol technology itself makes it possible to create batteries with high capacity, small size and weight, and without the “memory effect,” however, it is quite expensive.

- Ni-Cd. A relatively old battery manufacturing technology, the predecessor of the Ni-Mh described above. The common features of these technologies are resistance to high charge and discharge currents, low temperatures, and low cost. True, nickel-cadmium batteries are subject to the “memory effect” - a decrease in capacity when charging an incompletely discharged battery; however, this can be corrected by using advanced chargers and following operating instructions. But the clear disadvantage of this option is considered to be environmental unsafety during production and disposal; This is typical for all batteries, but it is most relevant for Ni-Cd cells, so they are used less and less.

— Li-Ion. Batteries made using lithium-ion technology and not belonging to any of the universal standard sizes (like AA). Lithium-ion batteries are practically not subject to the “memory effect”, are easy to use and charge fairly quickly. Their disadvantages include a higher price and less resistance to high and low temperatures.

— LiFePO4. Lithium iron phosphate batteries are actually a modification of lithium-ion batteries (see the corresponding paragraph), developed to eliminate some of the shortcomings of the original technology. They are notable above all for their high reliability and safety: the likelihood of a battery “exploding” when overloaded is reduced to almost zero, and in general LiFePO4 can cope with high peak loads without any problems. In addition, they are quite resistant to cold and maintain operating voltage almost until discharge. The main disadvantage of this type is its slightly smaller capacity.

— Branded battery. This category includes all specialized batteries (see subparagraph “Ni-Mh” above), for which the manufacturer did not indicate the manufacturing technology. We also note that if “ordinary” specialized batteries can be standard and can be used in different models of radio-controlled equipment, then branded batteries often have an original design and are designed only for cars from one manufacturer.

The operating voltage of the battery supplied with the machine. For models for AA and AAA cells (see “Battery Type”), it is not indicated — the specification of these cells assumes a common voltage standard, about 1.5 V. In other cases, battery voltage data does not play a significant role in everyday use, but may be useful , if you need to pick up a charger, a spare battery or a battery to replace a damaged one, but you do not have data on the battery model (see below).

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.

The number of batteries (namely AA or AAA batteries) required to operate the car.

The greatest distance between the remote control and the machine, at which the transmitter of the remote control is still able to guarantee normal controllability of the model. Note that official specifications usually provide data for perfect conditions: full battery charge, no obstacles in the signal path, extraneous interference, etc .; in fact, the range may be somewhat less. However, according to this parameter, it is quite possible to compare different models of radio-controlled cars with each other.

The higher this indicator, the farther you can let go of the machine from the remote control, the less often you have to move to keep control. However, a large range means not only a long range as such — it also speaks of a good signal penetration, its ability to pass through various obstacles.
