Serpent 411 ERYX

Esta é a nova versão do 411, mudou bastante coisa, parece que ficou melhor. Está mais baixo, com novo sistema de esterçamento, montante de motor, torres e amortecedores. Vejam mais fotos e o release da marca a seguir.


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 development team work of David Ehrbar and Michael Salven, feedback of Marc Fischer and other Team drivers and customers, was all combined to create this new Snake.

New Features

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
-Innovative floating servo-holder combined with steering-system; for less flex-influence
-Lower shocktowers FR and RR for lower CG
-Super - Short RCM shocks  with softer membrames (same springs as before) for lower CG and improved shock action
-New chassisplate 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
-1mm Lower  mid-shaft holder to allow more flex of the topplate
-Kit includes 2 type of alu support brackets for the motormount, allowing  more or less flex.

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 can 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

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

Innovative floating servo-holder combined with steering-system.
Serpent chief designer Michael and racer/designer David Ehrbar 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

Super - Short RCM Shocks
Serpent redesigned the RCM shocks to make them shorter to  mount them lower in the car and lower CG. The SS RCM shock are 6mm shorter than before.

This new shocks still keep same travel and volume as before and also enable use of the same length shocksprings as before ( or any other you may like to use). The shockbody has a shoulder in the top as limiter for the shocktop, so the membrame wont deform. The shockrod is sealed/supported with 1 or-ing and 1 bushing. Softer membrames make the update complete. The RCM SS shocks are used front and rear.

Lower shocktowers FR and RR

Lower shocktowers FR and RR for lower CG
The lower carbon shocktowers  enable the lower mounting of the shocks, 5,7mm lower than before, and thus lower CG. The shockowers offer mutiple angle positions.

New chassisplate - split blocks

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

Improved harder suspension M arms FR and RR  and harder 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

Lower  mid-shaft holder
1mm lower to allow more flex of the topplate. This creates a gap between the mount and the top-deck of 1mm to allow for more flex. In case needed the space can be filled up with shims and the 2 screws can be applied  to reduce flex.

Alu support brackets

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.
