Comparison WL Toys WL-24438-B 1:24 vs Maisto Rock Crawler Extreme 1:14

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.

— Highway. Also known as "touring". These are cars that outwardly copy passenger cars — both ordinary production cars and tuned ones, and even special cars like NASCAR cars. They can have a ring or drift purpose (see above), in general, they have high speed and good handling.

— Buggy. Full-size buggy-type vehicles are light all-wheel drive vehicles for off-road driving, primarily sand, with a characteristic body structure (angular panels, open frame elements, safety arcs) and suspension (wheels are most often noticeably moved to the side on the suspension arms). Radio-controlled buggies have a similar design. The body, however, is often stylized as racing cars, but this type of specialization is primarily off-road — for example, many short-course models (see "Destination") are specifically buggies.

— Truggy. This class is in many ways similar to the buggies described above, but differs from them in larger wheel diameters, longer suspension arms and increased ground clearance (see below). This may slightly reduce the speed, but increases the throughput; truggies are used for both short-course and trick riding (see Purpose/Class).

— SUV (monster). As the name implies, such models copy monster trucks — cars stylized as pickup trucks, the most striking feature of which are huge wheels, powerful engines and corr...esponding chassis features (large suspension travel, high ground clearance). Like the full-size originals, radio-controlled monster trucks are in many ways similar to buggies (see above), and differ from them only in the described features. "Monsters" are relatively poorly suited for high-speed driving, but they have high cross-country ability, due to which models for tricks and short courses are found in this type (see "Destination (class)").

— Rally. Such cars are a cross between "touring" and full-fledged SUVs. Outwardly, they are similar to road models, but have significantly more suspension travel, more powerful engines and improved mud protection. At the same time, rally cars are not designed for full-fledged off-road driving, overcoming significant bumps, etc.; their maximum is a dense coating like packed sand or fine gravel.

— Crawler. A specialized type of radio-controlled cars designed to overcome obstacles. Externally, the crawlers are somewhat similar to the “monsters” described above, but differ from them in a higher suspension height, which provides a characteristic silhouette: a body raised high on long “legs”. This design allows crawlers to cope with difficult obstacles — like stone scree with steep slopes. Note that the speed characteristics of this category of cars are quite modest, because. the emphasis in them is primarily on high cross-country ability.

— Changeling. Models of cars that even turned over will be able to continue moving. At the same time, from different sides, the body of the machine may look different. Such models have good cross-country ability and are considered stunt models (see "Purpose (class)").

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).

— Protection against moisture. The presence of protection in the design of the machine, which prevents moisture from entering the sensitive elements of the structure and the corresponding unpleasant consequences (short circuits, corrosion, water hammer, etc.). This feature is practically mandatory for outdoor models, especially off-road types with internal combustion engines (see above). However, the specific degree of such protection differs significantly in different cases: one model can be designed, for example, for a maximum of splashes from wet asphalt or light rain, while the other will calmly survive driving through a puddle “hood-deep”. Therefore, this point should be clarified according to the official data of the manufacturer.

— Protection against dirt. Protection to prevent dust and dirt from entering parts that require cleanliness. Similar in many respects to the water protection described above — in particular, it is very important for outdoor use and can vary significantly from model to model.

— Centre differential. The presence in the design of the machine of a differential located between the front and rear pair of wheels and distributing torque from the engine between the front and rear axles. By definition, it is found only in models with all-wheel drive (see above). The main function of this mechanism is similar to cross-axle differe...ntials — it allows the wheels, in this case the front and rear, to rotate at different speeds so that the chassis and tyres do not experience increased loads. A similar need arises, in particular, when cornering at low speed. In addition, the centre differential improves patency: when one of the pairs of wheels slips, it distributes the torque so that most of it falls on the wheels that retain traction.

— Metal main pair. The main pair is called two gears responsible for transmitting torque from the engine to the transmission: one of them is located on the engine shaft, the second — on the transmission shaft. This is one of the most important structural elements of the machine, which is subjected to significant loads during use. The main pairs made of metal are much stronger and more reliable than plastic ones; if you are purchasing a model for riding in difficult conditions (for example, a short course or tricks, see "Purpose (class)"), the presence of such equipment will be very desirable. At the same time, for entertainment purposes, it is rather an excess — after all, metal gears are more expensive than plastic ones.

— Anti-roll bars. The presence in the design of the machine of special devices that prevent the tipping of the structure to one side, in particular during sharp turns: during cornering, the stabilizer distributes the load on the wheels in such a way as to reduce chassis roll. However, this is not the only purpose of these parts — stabilizers of different stiffness are also a tool for distributing the grip balance between the front and rear axles. For example, if the front stabilizer is softer than the rear, the grip of the front axle will be higher, which ensures good steering, but reduces the sensitivity of the control; with a softer rear stabilizer — on the contrary. These points are described in more detail in special sources. It is worth noting that stabilizers are not a 100% guarantee against a coup — however, the likelihood of such an event is significantly reduced if they are present.

— Metal deck chassis. The deck is the basis of the chassis of the machine, the frame on which the engine, transmission and body are placed. The high strength of the deck is important for models that are subjected to significant stress during riding, for example, when used for short corsets (see "Purpose (class)"). Aluminium alloys are often used as a material for metal decks in modern cars — they combine good strength and low weight. However such materials also affect the cost of the model, respectively.

— Opening doors. Opening doors enhance the similarity of radio-controlled cars with real cars. You can put a toy driver behind the wheel of such cars in miniature, and passengers in the passenger compartment. Also, through the doors, access to the interior of the radio-controlled car is provided.

— Light effects. The presence of various lighting effects in the model: headlights, parking lights, flashing beacons (flashing lights), bottom lighting, etc. Such equipment not only makes the machine look like a real car, but also makes it more noticeable to others and reduces the likelihood of unpleasant incidents. At the same time, for advanced models, these moments do not play a key role, so lighting effects are found mainly in inexpensive entertainment cars.

— Sound effects. The presence in the model of various sound effects — for example, a horn, a siren, the sound of a powerful engine, etc.; sometimes there are even built-in melodies. To play sounds, usually, a small speaker is provided. This function is purely for entertainment purposes and is found only in simple and inexpensive models designed for the younger age group.

— Driver. A toy pilot seated behind the wheel of a radio-controlled car. The presence of a pilot allows you to give free rein to your imagination - driving a car from a distance, you can imagine that it is being driven by a little man.

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 maximum time that the machine can operate on a full battery charge. This item is very conditional, since it is measured when using the model not at maximum power. But in general terms, it can tell about the battery life of the machine.

The ability to charge the battery of the machine from a standard USB port.

This feature provides very extensive features for finding energy sources: USB ports are available not only in all computers and laptops, but also in various other equipment — TVs, car radios, etc. In addition, USB adapters are available for household sockets and car cigarette lighters. And in the absence of outlets nearby, the energy supply can be replenished from a standalone device — for example, from the same laptop or power bank. The disadvantage of this charging method is the relatively low power and poor suitability for high-capacity batteries, which is why it is found mainly in small entertainment machines.

The frequency at which the transmitter of the model control box operates.

— 27.145 MHz. One of the frequencies used for radio remote control for a long time; in some CIS countries it is even reserved by state regulatory bodies for this very purpose. Such transmitters are relatively inexpensive, but suffer from one serious drawback: they do not provide channel separation when several consoles are operating in close proximity to each other. In other words, if the machine stays in the coverage area of two transmitters, the signals from them will be mixed, which is actually tantamount to a loss of control. This is most often unimportant for recreational models, however, in competitions with several cars on the track at the same time, it can create serious problems and requires tricks with the design of the frequency grid and the use of interchangeable crystal oscillators. As a result, in professional motorsport, this frequency is gradually being replaced by the more advanced 2.4 GHz standard.

Separately, we note that among car models there may be transmitters with frequencies of 35, 40 and 75 MHz; according to the main features, they are completely similar to the described 27.145 MHz and differ only in the operating frequency.

— 2.4 GHz. The most advanced communication standard to date, used by remote control cars. Its main feature (and difference from those described above) is the possibility of normal operation of several transmitters of this...format in close proximity to each other. To do this, various technologies are used that provide automatic distribution of receiver-transmitter pairs over their own channels (similar to how it happens, for example, in mobile communications). Theoretically, the 2.4 GHz band may be more prone to interference, as many modern electronics work in it (in particular, Wi-Fi and Bluetooth modules); however, due to the aforementioned distribution of channels, such problems arise only in very unfortunate cases.
