Comparison Remo Hobby S EVO-R Brushless 4WD 1:16 vs Remo Hobby Smax Brushed 1:16

The minimum age for which this radio-controlled model is suitable. These recommendations are rather conditional, but it is still not recommended to deviate from them. "Adult" 14+ models with a lot of adjustments, moving parts and power simply will not be able to master a young rider of preschool and maybe even school age. At the same time, models for the younger age category ( 3+, 4+, 5+) may not be interesting and boring for older children ( children 6 and 8+). It is also worth noting that radio-controlled cars are not always children's toys and there are models for modeling, racing — professional use.

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).

— 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 an 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.

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

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 diameter of the wheels that the machine is equipped with.

In inexpensive " children's " or "entertainment" cars, the size of the wheels, usually, is not indicated at all — this parameter is relevant primarily for professional modellers who pay attention to all the nuances of the design. In general, larger wheels handle various bumps and obstacles better, while smaller ones allow you to achieve higher accelerations and top speeds. Accordingly, for high-speed racing it is better to choose smaller wheels, and for driving on rough terrain and overcoming obstacles — more. Detailed recommendations on a specific wheel diameter for different situations can be found in special sources.

The width of each of the front wheels of the machine.

It is worth paying attention to this indicator if the machine is purchased not just for entertaining “rides”, but for more serious purposes — racing on a track or cross-country, overcoming obstacles, etc. Other things being equal, wider wheels provide more reliable traction, have less pressure on the ground (respectively, the risk of getting stuck is reduced) and contribute to stability. Narrower wheels, in turn, have less weight and resistance, allow you to reach high speeds and make the machine more manoeuvrable.

Note that the front wheels are sometimes made narrower than the rear — this, in particular, makes it easier to turn them from side to side and reduces energy consumption when steering. This design is especially popular among buggies (see "Type").
