S120 Link by Serpent: Tunable 1/12 Pan Car Platform
The Serpent 410003 S120 Link combines lightweight carbon fiber construction with serviceable aluminum components to create a versatile 1/12 pan car kit. It is designed for racers who value precise adjustment and repeatable handling across different track surfaces.
Detailed Front Geometry
The front assembly offers a range of setup choices to dial in steering and turn-in. Fixed lower arms are paired with a central dampening strut using rubber o-rings for measured compliance. Upper wishbone mounts come anodized with multiple caster options, and a 6 degree mount is supplied for starting setups. Spring-loaded kingpins help route cornering loads through the upper arm for consistent corner entry.
Floating Monoshock Design
The lateral floating monoshock reduces chassis-to-motor pod flex and smooths transitions over bumpy sections. Changing piston sizes and shock oil viscosity gives noticeable differences in midcorner balance and roll control, making the car adaptable for low to high grip conditions.
Middle Section Setup and Roll Control
The central area uses a main shock plus spring-loaded lateral bars and pivot balls to control roll, bump, and alignment. This configuration, based on Serpent chassis concepts, helps maintain traction while preserving nimble handling.
Secure Bodywork and Battery Options
Robust adjustable body posts let you set body height for aero and clearance. Multiple battery mounting points and included Lipo spacers support different weight distributions, helping to tune front-end grip and rear traction.
Rear Drive Components and Ease of Service
The graphite rear axle and eccentric inserts enable quick ride height adjustments without striping threads. The ball differential uses quality steel balls and plates for long service life and straightforward maintenance access.
