The Serpent ERYX ERYX 4.0 is the next big  development stage for the 411 platform.   Featuring an ultra low centre of gravity, optimized weight distribution, high performance geometry and top quality materials throughout, the ERYX is your car for personal best times !

Michael Salven the Serpent chief onroad designer has worked intensively over summer  with  Marc Fischer and Viktor Wilck to  develop the 4.0  new parts. Most of the testing was done by Marc and Viktor and the parts have been used in recent races already.

SERPENT HERITAGE:

Serpent started of in the electric 1/10 class as early as 1990 already with the Tenforce full suspension car, designed by Rody Roem, former 1/8 gas onroad World Champion.  At that time all the racing was with pancars only,  so the TenForce was its time (too) far ahead.   Only years later the full suspension class became more widely accepted and grew into the largest onroad class overall.


Serpent re-started the electric touringcar line with the famous Serpent S400 in 2008, which was also successfully raced by Billy Easton. Later followed by the Serpent 411, which was renamed to ERYX since version 2.0.   Michael Salven is in charge of the design of the touringcar class, with assistance of very active racers in this category.  In the latest update of the 411 platform, the ERYX 4.0.

CHASSIS PLATE ALU:

The newly designed very narrow chassis plate has been machined from 2mm 7075 6 aluminium, lowered sides to lower the center of gravity and mount the electronics lower.  All holes in the base of the chassis have been countersunk . The chassis further features extra holes to mount weights and additional stiffners .  All holes are as close to the centerline of the chassis, to create even flex.

CHASSIS PLATE CARBON FIBRE:

The newly designed very narrow chassis plate has been machined from 2.25mm carbon fibre, lowered sides to lower the center of gravity and mount the electronics lower.  All holes in the base of the chassis have been countersunk . The chassis further features extra holes to mount weights and additional stiffners .  All holes are as close to the centerline of the chassis, to create even flex.

DJC/CVD'S SPRING STEEL:

This car is supplied with a complete set of 4 high quality hard coated spring-steel CVD shafts, which are a highly consistent, efficient and durable way to transfer all the power the surface. The front ones are v2 type double joint cardans DJC, the rear regular CVD style shafts.

DJC/CVD'S SPRING STEEL:

Steering Assembly

STEERING ASSEMBLY:

The Serpent ERYX utilises a centrally mounted ballraced dual pivot steering assembly-rack in aluminium. Offset steering linkage for correct steering geometry and ackermann. The steering assembly allows for very precise steering and great control. The ackermann is adjustable by using shims. The system pivots on wider low steering-shafts, creating a more direct steering feel. The bearing in the levers are pressed inside for a play-free assembly.

UNIQUE SERVO HOLDER:

The unique and innovative servo holder has zero  influence on tweak, as its floating above the chassis and mounted directly to the steering-assembly in the center of the car. This also keeps the weight lower than any other design.

UNIQUE SERVO HOLDER
SHOCK TOWERS

SHOCK TOWERS:

The Serpent ERYX features lowered shocktowers 2.5mm thick carbon fibre shock towers on the front and rear of the car.  Each tower sports many 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.

SUSPENSION BRACKETS:

For adjusting the cars toe-in and track-width, the ERYX is equipped with seperately mounted suspension brackets on both the front and rear of the car. Each bracket features an easily recognisable number that corresponds to the setting being used and due to the way they are mounted allows the user to easily and accurately adjust their cars settings.  The brackets  are designed such way that they can be used in any position in the car.   The inner brackets FR and RR are now split type, to allow for more flex.   The split suspension blcoks are mirror type, so you can use them either left or right and obtain  a different desired setting.  This way less different blocks are needed for a good variety of settings. Standard ones:  :  3.5/ 0.5 split blocks in the rear, 2.0/ 0.5 in the  front

BUMPER:

The front bumper has been made from a high impact absorbing foam material and is shaped to protect the entire front end of the car in the event of a crash. The bumper is held in place with a large top-plate.

Suspension Brackets and Bumper
BATTERY STAYS CARBON/ALU

BATTERY STAYS CARBON/ALU:

The battery pack is kept in place by 2 mounts on the centreline of the car, and 2 special carbon/alu  mounts with slits to mount the glass-tape.  The carbon brace can be easily moved fronr or rearwarsd  to move the battery more forward or backwards.  Below these these the carbon Lipo battery holders are mounted.

CENTRAL SECTION:

The new one piece machined aluminium motorbracket is superlight and superlow and suits both stock and mod gearing well.   The small front alu bracket, can be fitted with an alu bushing with long screw to connect to the top-deck. It can also be removed to create extra flex.  The seperate machined brackets hold the light aluminium middle shaft/ 19T pulley.

Central Section
IDENTICAL

IDENTICAL:

The front and rear end of the Serpent ERYX are fully indentical and 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 are anodized in gun metal grey.

REAR SECTION WITH HARDER ARMS:

The rear end of the ERYX features stronger  Hard lower wishbones . 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 Hard upright features a pivot pin mounting point on the bottom and 2 upper camber link mounting holes for fine-tuning camber rise.

REAR SECTION WITH HARDER ARMS
ANTI-ROLL BARS

ANTI-ROLL BARS:

The ERYX is supplied with coded anti-roll bars front and rear with a composite centering bracket. The anti-roll bars are available in a number of thicknesses and are connected to the wishbones using short adjustable track rods, connected with a pivot ball to the lower front wishbone, and with a ball directly to the rear lower wishbone.

The anti-roll bars run in small tapered nylon inserts , and the anti-roll bar is centered through one captured center bushing.

.

BIG BORE SHOCKS:

The new Serpent bigbore onroad shockabsorbers lower the center of gravity even further. They come with threaded coated shock-bodies, pre-load shock nuts with o-ring, harder  membrames , supersmooth and strong shock-rods with clip  to hold the piston, perfectly machined pistons ( 1,2,3 and 4 holes in kit) in a new yellow material , toplevel x-ring /bushing package,  light spring-cups, strong balljoints.  The  advantage is that you can continue using the normal size springs as before.

High quality race-springs included with color coding, grinded flat for even load.
HARDER C-HUB FRONT

HARDER C-HUB FRONT:

A standard system on most high-end touring cars, the ERYX features a front C-hub system in Hard composite. The car comes standard with a 4-degree caster block but is also supplied with a pair of 2 and 6-degree blocks.  The C-hub is large enough to take out the drive-shaft assembly without dis-assembling the c-hubs.

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 an aluminium  track rod which is solid, lightweight and can easily handle impacts.

FRONT SUSPENSION
SPOOL

SPOOL:

The car comes supplied with a front spool which has been made from hard anodised aluminium and are used with blades to increase lifspan. The shape has been optimised to ensure that the part is as light as possible without compromising strength.

BELTS - DRIVETRAIN:

The ERYX features a 2-belt configuration with a long front and a short rear Kevlar reinforced low friction belt that combied with precision moulded gears makes for a super smooth and free drive train.

BALL BEARINGS:

The ERYX is supplied with high-quality lightweight bearings with orange seals throughout, making the drive train very efficient and allowing it to run very smoothly.

COMPOSITE GEAR DIFFERENTIAL WITH NEW MATERIAL COMPOSITE GEARS AND X-AXLE:

The ERYX comes supplied with a lightweight and smooth rear gear-differential.  This supersmall differential can handle all the power of BL motors.   Gear-diff can also be used on the front. The new version has new type composite internal gears and 3.5mm x-shape shaft and features coated aluminium outdrives.   The metal gears can also still be used or mixed with composite.  ( The ball-diff is optional).
