Motor model
The name of the engine installed on the boat. 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 professional grade model.
In addition to the name, this paragraph may also specify the type of electric motor (see "Motor") — collector or brushless.
The collector design 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 units. In addition, with a collector motor, it is more difficult to ensure high speed. As a result, this option is typical for relatively inexpensive and slow models.
Brushless motors are considered more advanced than brushed motors: they are more powerful, more economical, more durable, better protected from pollution and are 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 predominantly used in advanced high speed craft; the presence of such a motor is an indicator of a rather high class model.
Radio-cont...rolled models can be produced in two versions, differing only in the type of electric motor.
Maximum speed
The highest speed the boat can reach. For ARR models (see Package Contents) it is usually specified if the recommended battery is used; when you install a battery with a lower voltage, the speed also decreases.
Note that the maximum speed is traditionally given for perfect conditions: good weather, no waves, a full battery charge, etc. Therefore, in fact, it may well be lower than stated. Nevertheless, this figure describes the vessel's capabilities quite well. When choosing by speed, it is worth remembering that the faster the model, the more expensive and demanding it is to control skills, and the more free space you will need for its safe use. Therefore, it makes sense to specifically chase high speed values except for
sports use.
Battery voltage
Rated voltage of the battery supplied with the boat.
The voltage is selected by the manufacturer in such a way as to provide the required performance. Therefore, in general, it is a secondary parameter; you usually have to pay attention to voltage only when looking for a replacement battery or charger.
Note that in modern radio-controlled equipment, including boats, batteries with a standard voltage of 3.7 V, 7.2 V and 11.1 V have become widespread. volt battery instead of 3.7 volt battery for more power and speed.
Battery model
Model of the battery supplied with the boat. This data allows you to find detailed information about the battery and evaluate its characteristics; they also come in handy when looking for a spare or replacement battery.
Operating time
Operating time of the boat on one charge of the complete battery. This indicator is rather conditional, because. usually it is indicated for a certain average mode of operation, as they say, "without extreme"; the time of continuous movement at full speed can be noticeably less. Nevertheless, it fully allows you to evaluate the battery life of the boat.
Note that for models powered by AA and AAA cells (see "Battery type"), the operating time is not indicated: such cells may have different capacities, and, accordingly, the battery life of the model in each case will also be different.
