Comparison Xiaomi R-Racing RCSB-001 1:18 vs Himoto Spino E18XBL 1:18

— 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 name of the engine installed in the machine. Usually, knowing this name, you can easily find information about the features of the engine — both official manufacturer data and reviews from users — and determine how much you are satisfied with its characteristics. This can be very important when choosing a model for professional motorsports.

In addition to the name, this paragraph can also specify the type of electric motor (see "Engine") installed in the machine — collector or brushless.

The collector design of the electric motor can be called classical. It allows you to create fairly light, compact, inexpensive motors, which are also easily repaired. The disadvantages of this option are relatively low efficiency, a tendency to spark (especially when overheated), as well as less durability than brushless models. In addition, with a collector motor, it is more difficult to ensure high speed. As a result, this option is typical for entry-level and middle-level models (relatively slow).

Brushless motors are considered more advanced than brushed motors: they are more powerful, more economical, more durable, better protected from pollution and well suited for overclocking to high speeds. On the other hand, such engines are much more expensive, and the complexity of the design does not allow you to repair the motor on your own. In light of all this, brushless motors are used primarily in advanced high-speed cars; the presence of such a motor is an ind...icator of a rather high class model.

Some models of radio-controlled cars can be produced in two versions, differing only in the type of electric motor.

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).

Type, model and other features of shock absorbers installed in the car. For details on the meaning of this parameter, see "Motor model".

— 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 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).

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 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.
