Product	400013 Serpent 411 – ERYX 2.0

Serpent 411 ERYX 2.0 introduction

The Serpent 411 ERYX 2.0 is the next big development stage for the 411 platform. Featuring an ultra low centre of gravity, lighter, optimized weight distribution, high performance geometry and continue top quality materials throughout.
The new  version was used at the recent DHI Cup with Fischer qualifying 2nd and taking 3rd in the final, superclose to Volker and Berntsen.  3 x 411-Eryx in the A-main !
Key new items in the 411 ERYX 2.0

• 
  Lighter geardifferential with composite gears and coated alu outdrives; less rotating mass and smoother
  
• 
  Lowered steering system; for more direct steering feel and lower CG

More info to the new specs:

Lighter geardifferential with composite gears and coated alu outdrives

The geardiff housing is super compact and light already. For the new diff the small and large gears inside are made from a very durable and smooth composite, and the alu axles ar replaced by a composite X-shape axle . The steel drivecups are replaced by coated alumnium ones. The result is less rotating mass and smoother diff action.

The sintered alu gears and still be used in the diff-case, and some drivers also combine alu and composite gears for different gear-diff feel/ action.
Lowered steering system; for more direct steering feel and lower CG

The steeringposts are a much lower version than before, resulting in a lower CG and a more direct steeringfeel.

Innovative floating servo-holder combined with steering-system.

Serpent chief designer Michael and racer/designer David looked at all the new servo-holders recently introduced by other brands, but did not like the systems. The early version of the 411 car already featured a different servomount plate, which hardly influenced flex at all and was simple and worked fine. Time to take a fresh look at things and try to make something really new, and that worked out.

The new system is mounted directly to the steering-system, and a carbon fibre holder flows around the servo, and the servo thus floats above the chassis. The direct connection to the steering system and thus to the center of the car, makes it the optimal solution, and it also keeps the CG even lower and weight more centerered in the car.
Super - Short RCM Shocks

Serpent redesigned the RCM shocks to make them shorter to mount them lower in the car and lower CG. This was achieved and same time keep same travel and volume as before, and also enable use of the same shocksprings as before ( or any other you may like to use) . Softer membrames make the update complete. Same SS shocks used front and rear.

Lower shocktowers FR and RR for lower CG

The lower carbon shocktowers enable the lower mounting of the shocks and thus lower CG. The shockowers offer mutiple angle positions and the front one allow mounting a 3rd bodypost

New chassisplate 2.25mm for mounting split blocks

Split suspension brackets inner FR and RR for more flex

To allow more chassisflex Serpent tested the use of split supension blocks since the Wc 2012. Both on front and rear the inner suspension mounts are now split type blocks. The new holders are made such way that they can be used either left or right side and have different setting that way, mirrored. The kit also includes new size 0.5mm spacers for further finetuning.

The new 2.25mm chasiss allows space for mounting of the new split system.

Improved harder suspension M arms FR and RR and C-hubs for more traction

The front and rear arms have been beefed up by adding material in some area’s. Stress simulation software was used to analyse the flex to able to add material in exactly the right locations. Also the composite material used is a new harder version. Same for the c-hubs. A new H type arms ( so even harder than new M arms) will follow later this year.

Lower mid-shaft holder

1mm lower to allow more flex of the topplate. In case needed the space can be filled up with shims and the 2 screws can be applied to reduce flex.

Kit includes 2 type of alu support brackets for the motormount, allowing more or less flex.

The bracket to hold the motormount in the center of the car. There are 2 versions and both are included, so you may choose the optimal one per track.
