Introduction
Serpent enters the competitive electric touring car market with the S400, which like all our previous cars, has been designed to win straight out of the box. Featuring an ultra low centre of gravity, optimized weight distribution, high performance geometry and top quality materials throughout, the S400 should see you in the winner’s circle in no time. In fact everything associated with this car is of the highest quality, from the packaging and supplied manuals, right through to the product and race support.
Rear end
The rear end of the Serpent S400 has been designed for high performance and ease of maintenance. The rear bearing blocks have been designed in 2 pieces which allows the topside to be simply removed with 4 screws, giving you easy access to the differential for maintenance or adjustment. All the parts have been machined from aluminium and have anodized in gun metal grey.
Rear suspension
The rear end of the S400 features strong 1-piece lower wishbones and aluminium uprights. As with all the wishbones on the car, the lower wishbones can be used on both the left and right sides, minimizing the number of spare parts needed to bring to the track. The rear upright features a pivot pin mounting point on the bottom and three upper camber link mounting holes for fine-tuning camber rise.
Rear Differential
The kit version of the S400 comes supplied with a lightweight and smooth rear ball differential. The diff halves are made from hard anodised aluminium which is lightweight yet extremely strong, while the use of high quality balls and steel plates ensure a long lasting and smooth diff action.
Drive train
The S400 drive train utilizes a 2-belt system with rear ball differential and front spool, while 4 CVD (constant velocity drives) transfer the power to the wheels. The motor, which is mounted to an aluminium plate, powers the main spur gear and hard anodised aluminium pulleys.
Front suspension
Similar to the rear suspension in configuration, the front suspension sports a lower composite wishbone while the upper camber adjustment is handled using a track rod which is solid, lightweight and can easily handle impacts.
Front C-hub system
A standard system on all high-end touring cars, the S400 features a front C-hub system, which is a lighter alternative to a pivot ball steering system. The car comes standard with a 4-degree caster block but is also supplied with a pair of 2 and 6-degree blocks.
Servo Saver
The servo saver on the S400 features 4 steering rod mounting points to allow the user to easily adjust the cars Ackerman. The servo saver system itself features a nut for adjusting the spring tension of the saver.
Chassis
The chassis plate has been machined from a plate of 2.5mm thick carbon fibre, which creates a perfect platform for the cars electronics as well as stiff structure, especially when combined with the equally rigid 2.5mm thick carbon fibre top deck. All holes in the base of the chassis have been countersunk while on the top of the plate, the area around the motor has been milled down to allow it to sit as low as possible. The plate features cooling holes below the motor and speed controller.
Anti-roll bars
The S400 is supplied with colour coded anti-roll bars front and rear that are held in place using a 2 piece anti-roll bar mount. The anti-roll bars are available in a number of thicknesses and are connected to the wishbones using short adjustable track rods. Stiffness is quickly and easily adjustable by changing the linkage mounting points on the lower wishbones or alternatively by changing the position of the ball joint pivot point on the roll bar itself.
RCC Shock absorbers
The RCC shock absorbers are the smoothest and easiest to build shocks ever designed. Machined from aluminium and unique in that the shock bodies only open on the bottom half, they are really simple to assemble. The result is an ultra-smooth and air-free shock absorber thanks to the self-bleeding system incorporated into the design. The shocks are supplied with 4 different shock pistons.
Another great benefit is that these shock absorbers come pre-assembled in the kit, so you need only add shock oil.
Front axle
The car comes supplied with a front spool which has been made from hard anodised aluminium while its shape has been optimised to ensure that the part is as light as possible without compromising strength. The drive is provided through the attached pulley into the lightened steel drive cups, which are held in place using steel pins.
Shock towers
The Serpent S400 features 2.5mm thick carbon fibre shock towers on the front and rear of the car. Each tower sports numerous holes for adjustment of the shock absorber angle while the rear tower also acts as the mount for the rear body posts and the front tower accommodates a 3rd front body post.
