Review by Andrea LEO (RC LEO Andrea on Facebook) who since 2017 collaborates with HighestKorea and the distributor for Italy "IconRc" as tech support and driver.
We wanted to enter the heart of one of the last born of the "Highest" house, the Torque B210 with brushless motor, but to do so, to lift a lot of "strength" contained in just 73 g of weight, we needed "heavy vehicles" "and so we used our best bulldozers.
The now proven Korean company Highest, which in recent years has made itself heard on all tracks and competitions in the world, introduces the new Torque B210 servo to the market, offering all drivers of categories 1/8 Off-Road and 1/8 On-Road, an electronic engineering masterpiece combined with top-level mechanical features.
But let's go "Step by Step" as the British say.
The elegant packaging of our B210 contains inside a dedicated 25T black aluminum bracket including "Highest" engraving and an additional safety closure that allows together with the main fixing screw to obtain an effective and stable anchorage of the bracket.
Nothing has been left to chance and therefore the four aluminum bushings that recall the red color of the elegant lines on the black anodized case could not be missing. Elegance is at the highest level.
The case, built entirely of 6061-T6 aluminum to facilitate the dissipation of the heat generated during use, is divided into four parts, each including a sealing O-ring against the intrusion of dust and humidity, "modeled" with machines CNC that accentuate its extraordinary machining precision. Very important is the presence of the particular o-ring placed inside the case in the upper part, which creates an additional seal that makes it impregnable.
The gears, made of high-strength steel, are supported by two 6x10x2.5 size bearings built according to the best precision standards to which, after a first examination, we can attribute an Abec 5-7 construction tolerance, a specification that ensures a transmission extremely smooth, a decrease in vibrations and therefore a feeling of fluidity while driving.
In the lower part we find the PCB with all its components and of course our MCU (Micro Controller Unit), that is a 32-bit microcontroller with a high efficiency architecture, could not miss. These numbers refer to the dimensions of the data buses, that is, with a larger data bus, it is possible to perform more complex calculations by the microcontroller.
When we ask for precision we need a higher quality potentiometer, and Highest has not failed to meet our expectations, offering the B210 a potentiometer capable of having a constant millimeter precision of the position of the servo and a longevity that translates into 1,000,000 of guaranteed cycles.
But let's get to the strong point, where technology and innovation come together to create an extraordinary Brushless motor with very high efficiency and Japanese manufacture, specially designed to obtain an engine torque of 31.1 Kg/cm at 7.4V at a "slew rate" of 0.09sec/60 °.
I can say that with the aforementioned characteristics, the Torque B210 servo together with the brother Speed B200, are candidates for the throne of the best servos currently on the market in terms of performance and reliability.
