Comparison Remo Hobby Mmax Brushed 1:10 vs Remo Hobby Mmax Brushless 1:10

— RTR (Ready to Run) — the box contains a fully configured and ready-to-run model. Such models are equipped with a battery, a remote control, and a charger.

— ATR (almost-ready to run). The model is almost completely ready for use, but some of the elements are still missing. The list of missing components can include both a battery and a remote control or charger. All of the above components may be missing at once. Missing parts must be purchased separately. Models in the ATR package are designed for advanced users, this package allows you to choose batteries or controls based on your own needs and requirements.

— PNP. the receiver and transmitter are not included in the package, and often there is no battery. Additionally, the PNP set may not contain control equipment. Radio models in the PNP configuration are designed for professionals who often use individual electronics. Usually, the design of the model itself is collapsible, which significantly increases the maintainability of the product. Many models sold in the PNP configuration are allowed to participate in prestigious exhibitions and competitions.

— K.I.T. For the most part, only body parts are provided in the kit. The kit has a lot in common with the designer, because from such a kit it is possible to assemble various options for the body of the radio model. The KIT package includes neither radio communication mod...ules, nor control equipment, nor electric motors. That is, the user will have to buy / manufacture all the hardware of the radio-controlled model on their own. Radio models in the KIT package are designed for advanced users. KIT kits are suitable for assembling advanced models, which are often used in prestigious exhibitions and sports competitions.

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 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 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).
