Ultimate Racing RSX8 1/8 37KG 0.075s. Brushless Servo W/ UR1813-25 Horn

This is the RSX8 Brushless Servo with the stearing servo horn UR1813-25 from Ultimate Racing, designed for 1/8 scale cars and with performance figures of 37 kg and 0.075 s. It meets all the durability, performance, and quality requirements needed for the highest level of competition. It can be used for both steering and throttle/brake.  

A black anodized aluminum top case and a red anodized aluminum bottom cover give this servo a distinctive look. The 5 grooves on the top case and 7 grooves on the bottom cover provide efficient heat dissipation and help reduce weight.  

In this servo, the O-ring seal has been repositioned inside the screws to prevent moisture from entering through them.  

This servo does not require washers for assembly. The servo mounts have countersinks for using tapered screws, allowing for assembly without washers. It includes 4 M3x14mm tapered screws.  

It comes with two flat rubber pads perfectly shaped for the servo to be mounted between the servo and the radio tray, acting as both a silent block and to prevent the bottom of the servo from touching the chassis. These rubber pads are much better than conventional ones because they reduce vibrations, prevent the servo from moving and do not deform when screws are tightened.  

It includes an M3 cap head screw to mount the servo horn. This screw is ideal for the different servo horns from Ultimate Racing.  

The servo packaging is an EVA box with the Ultimate Racing logo, which can be reused for other purposes.
