Jan 17, 2013 No Comments by

This new touring car is loaded with great features like an independent suspension, a carbon fiber chassis and top deck, aluminum suspension mounts, and much, much more. Check out all the details below:

The Serpent 411 ERYX 2.0 is the next big development stage for the 411 platform. Featuring an ultra-low center of gravity, optimized weight distribution, high performance geometry and top quality materials throughout, the S411 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.

Key new items in the 411 ERYX 2.0

  • Lighter gear differential with composite gears and coated alu outdrives; less rotating mass and smoother
  • Lowered steering system; for more direct steering feel and lower CG
  • Innovative floating servo-holder combined with steering-system; for less flex-influence
  • Lower shock towers FR and RR for lower CG
  • Super – Short RCM shocks with softer membranes (same springs as before) for lower CG and improved shock action
  • New chassis plate 2.25mm for mounting split blocks
  • Split suspension brackets inner FR and RR for more flex
  • Improved harder suspension arms FR and RR and C-hubs for more traction
  • Kit includes 2 type of alu support brackets for the motor mount, allowing more or less flex.

Ball-bearings

The 411 is supplied with high-quality lightweight bearings throughout, making the drive train very efficient and allowing it to run very smoothly.

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. The lower plate can be cut to the desired size and shape.

Steering assembly

The Serpent 411 utilizes a centrally mounted balanced dual pivot steering assembly-rack in aluminum. 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 now pivots on lower steering-shafts, creating a more direct steering feel.

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.

Suspension brackets

For adjusting the cars toe-in and track-width, the S411 is equipped with separately mounted suspension brackets on both the front and rear of the car. Each bracket features an easily recognizable 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 blocks 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.

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.

Chassisplate

The newly designed very narrow chassis plate has been machined from a plate of 2.25mm thick carbon fiber, which creates a perfect platform for the cars electronics as well as stiff structure, especially when combined with the flex type 2.0mm thick carbon fiber 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 chassis further features extra holes to mount weights and narrow slits to guide the battery-tape. All holes are as close to the centerline of the chassis, to create even flex.

Battery-stays

The battery pack is kept in place by 2 mounts on the centerline of the car, and 2 special nylon mounts with slits to mount the glass-tape. The mounts can be reverted to move the battery more forward or backwards. Below these the carbon Lipo battery holders are mounted.

Belts – drivetrain

The S411 features a 2-belt configuration with a long front and a short rear Kevlar reinforced low friction belt that combined with precision molded gears makes for a super smooth and free drive train.

Lower Shock towers

The Serpent S411 features lowered shock towers 2.5mm thick carbon fiber shock towers on the front and rear of the car. The upper shock-mount height is now 5,7mm lower than in the 411-TE. 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.

Spool

The car comes supplied with a front spool which has been made from hard anodized aluminum while its shape has been optimized 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. ( a composite spool is optional )

Anti-roll bars

The S411 is supplied with coded anti-roll bars front and rear with alu 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 wishbones.
The anti-roll bars run in small nylon inserts in the right size same as the anti-roll bar, and the anti-roll bar is centered through one captured center bushing.

Harder C-hub front

A standard system on all high-end touring cars, the S411 features a front C-hub system. 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 a track rod which is solid, lightweight and can easily handle impacts.

Rear section with improved harder arms

The rear end of the S411 features stronger lower wishbones and composite. 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 2 upper camber link mounting holes for fine-tuning camber rise.

Identical

The front and rear end of the Serpent S411 are fully identical 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 aluminum and are anodized in gun metal grey.

Central section

The motor bracket is separated fully from the aluminum mid-shaft brackets to isolate motor-vibrations better. The separate machined brackets hold the light aluminum middle shaft/ 19T pulley. The now 1mm lower holders feature separate alu bearing holders, which give the best possible support to the mid-shaft section. The 1mm lower mid-shaft holders allow more flex of the top plate. In case needed the space can be filled up with shims and the 2 screws can be applied to reduce flex. The kit features 2 versions of the alu support bracket, to allow for more or less flex.

Composite Gear differential v2 with composite gears and X-axle

The S411 comes supplied with a lightweight and smooth rear gear-differential. This super small differential can handle all the power of BL motors. Gear-diff can also be used on the front. The new version has composite internal gears and 3.5mm x-shape shaft and features coated aluminum outdrives. The metal gears can also still be used or mixed with composite. ( The ball-diff is optional).

Super Short RCM Shocks

The new super-short Serpent on road shock absorbers lower the center of gravity even further. They come with threaded hard coated shock-bodies, pre-load shock nuts with o-ring, softer membranes , super smooth and strong shock-rods with nut to hold the piston, perfectly molded pistons ( 1,2,3 and 4 holes in kit), top level o-ring /bushing package, light spring-cups, strong balljoints. Main advantage is better response of the shocks under hard sudden impact, e.g. when touching a curb.

The volume of the SS shocks remain same as the earlier short shocks, and the key 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.

Set-up

Ackermann: two positions on the steering blocks , and the steering plate with shims
Camber: adjustable front and rear
Toe-in: adjustable front and rear
Front Caster: 4° static ( 0°, 2° or 6° as optional )
Downstops: adjustable front and rear

Packing

The S411 kit comes without body/tires/spur gear and electronics. Its packed in a very small strong box with nice graphics, which can be re-used as parts or tire box later on. The box contains bags which are numbered in same sequence as steps in the manual.

Manual / decal / set-up sheet

To allow you to build your car with the greatest of ease, Serpent supplies a full color instruction manual and integrated reference guide section that contains all the exploded views and latest options. Serpent 411 logo decal sheets and set-up sheet are included.
