This is the 37 Kg. and 0.075 s. Ultimate Racing RSX8 Brushless Servo for 1/8 cars that meets all the durability, performance, and quality requirements necessary for the highest level of competition. It serves both for steering and throttle/brake.
An anodized black aluminum top case and a red bottom cover made of the same material give this servo a distinctive look. The 5 lines on the top case and the 7 on the bottom cover provide efficient heat dissipation and help reduce weight.
In this servo, unlike others, the location of the sealing O-ring has been changed, placing it inside the screws to prevent moisture from entering through them.
This servo does not require washers for installation. The servo mounts have countersinks to use conical screws and install it without washers. It includes 4 M3x14mm conical screws.
It incorporates two flat rubber pads shaped exactly like the servo to mount between the servo and the tray, acting both as a silent block and a riser so that the bottom of the servo does not touch the chassis. These rubbers are much better than conventional ones because they reduce vibrations but do not allow the servo to move or deform when tightened.
Includes a cylindrical head M3 screw for mounting the servo arm. This screw is ideal for the different servo arms from Ultimate Racing.
The servo packaging is an EVA box with the Ultimate Racing logo, reusable for other purposes.
