Comparison Sulong Toys Speed Racing Drift Sword 1:24 vs Sulong Toys Off-Road Crawler Rock 1:18

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).

— 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)").

— Full. As the name implies, in such models, traction from the engine is transmitted to all 4 wheels. The main advantage of this scheme is its high cross-country ability: the machine keeps well on difficult terrain, and even getting stuck with a pair of wheels in the air is not critical for it. Also, four-wheel drive can be used for drifting (see "Appointment (class)"), although it loses a little in this role to the rear one; however, a lesser tendency to drift can be an advantage. Its main disadvantage is the rather high cost associated with the difficulties in production. In addition, 4WD vehicles tend to be less fuel efficient than "single wheel drive" vehicles.

— Rear. Models with power transmission from the engine to the rear pair of wheels. This scheme is quite unstable and requires careful control at high speeds — if you turn too sharply, the car easily goes into a skid. On the other hand, it is precisely because of the instability that this option is considered optimal for drift racing, and the design of the rear-wheel drive is very simple, reliable and inexpensive. As a result, most non-4WD RC models use it.

— Front. The front-wheel drive has a high degree of stability: you can only send the car into a skid intentionally (and then you need to try hard), and the withdrawal from it is extremely simple. At the same time, stability is not always a...n advantage — for example, in drifting, it only creates additional problems. In addition, the design of such models is quite complex due to the need to combine the drive from the engines and steering on the same pair of wheels; as a result, in terms of price, reliability and ease of maintenance, they lose to rear-wheel drive. Therefore, front-wheel drive is not widely used in radio-controlled cars.

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

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.
