Japanese company KO Propo have introduced the RSx3 line of standard size high-performance servos. The range includes the RSx3 Response HC (0.06s/17.6kg-cm) and RSx3 Power HC (0.11x/31.6kg-cm) with aluminium upper cases as well as the RSx3 Response (0.06s/17.6kg-cm) and RSx3 Power (0.11s/31.6kg-cm) with composite upper cases. All four feature aluminium middle sections with laser-etched graphics, they are high-voltage compatible, allowing to use them with up to 7.4V input, they are equipped with hard-anodised aluminium gears, coreless motors, gold-plated connectors and black servo leads. On top of this the RSx3 line makes use of KO Propo’s new Highspeed Communication System HCS, in combination wit HCS-compatible receivers, for a more linear steering feeling and they are programmable using the company’s ICS Servo Manager software in order to fine-tune the servo’s behaviour for different classes or track conditions.
