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.

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.

2145-eryx3.0_14.jpg

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 now pivots on lower steering-shafts, creating a more direct steering feel. The bearing in the levers are pressed inside for a play-free assembly

2145-eryx3.0_05.jpg

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 ERYX is equipped with separately 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

2145-eryx3.0_07.jpg

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.

Chassisplate

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.

2145-eryx3.0_04.jpg

Battery-stays

The battery pack is kept in place by 2 mounts on the centreline 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 these the carbon Lipo battery holders are mounted.

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.

2145-eryx3.0_15.jpg

Lower Shocktowers

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

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.

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.

Rear section with improved 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.

Indentical

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.

Central section

The new machined alumnium motorbracket is superlight and superlow an suits both stock and mod garing well. The motormount and middleshaft holder assembly with 2 longer legs connect to a seperate small alu bracket. 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.

Composite Gear differential v2 with 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 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).

Super Short RCM Shocks

The new super-short Serpent onroad shockabsorbers lower the center of gravity even further. They come with threaded hard coated shock-bodies, pre-load shock nuts with o-ring, softer membrames , supersmooth and strong shock-rods with nut to hold the piston, perfectly moulded pistons ( 1,2,3 and 4 holes in kit), toplevel 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.

De nouvelles photos (12) -> http://www.petitrc.com/gallery/browseimages.php?c=222

Avec une interview du designer de la voiture, Michael Salven :

an interview with Michael Salven, designer of the ERYX 3.0 (and chief designer for Serpent, as well as main shareholder of Serpent).

Hello Michael,

Below we like to ask you some questions concerning the introduction of the new ERYX 3.0

Q: Which drivers and developers are mainly working on such new version, and when did you get started ?

A: In Germany we have 2 key drivers that assist in the development of the 411 ERYX, which are Marc Fischer as topdriver and David Ehrbar as driver and analyser/engineer. At the races and on internet we pick up the feedback of drivers, and together with my own experience in racecar design, we decide on the developments. You cant really say when we started as its an ongoing process, day and night  but at some point you need to decide an introduction date and confirm what to include. Many new idea’s are being developed and tested again now, as we also are in the year of the Worlds in USA ….

Q: The ERYX 3.0 has the aluminium chassis as standard. Why did you choose that and what is specific about the design ? and please also confirm that earlier versions of the carbon chassis, like the hard 2.0 and the 2.25 chassis still fit.

A: We have performed tests with a number of aluminum chassis, different shapes, thickness and with lowered side area’s and without, indoors and outdoors and decided pretty fast for this final one, as its always better so far. The lowered section on the side influence flex in the right way, as a full alu plate is too stiff. The lowered area also means the battery and other components can be mounted very low, which is good for center of gravity. The carbon chassis as used on the 411 1.0 and 2.0 also still fit, and the 3 version topdecks too, so you can “play”with many variations depending on the track and griplevels..

Q: What effect has the new motormount you developed ?

A: The motormount is a lot lighter and very low and its mounted to the alu chassis very close to the centerline, so influence on flex is even. It doubles up as midshaft holder . Both for stock and mod it fits very well.

Q: we all know that playing with flex in Touringcar is a big thing, what has the ERYX 3.0 to offer in that repect

A: Main component is the new alu chassis for sure with the lowered sides. Then the flex type topdeck plays a main role. The topdeck mounts to the front and rear brackets and there is an additional mounting point near the motormount using a spacer. On top of that we have an optional stiffener which mounts in the centerline of the car. When you use that, you have two options to use the spacer, in the rear and near the front. You can use the spacer then only front or only rear or both. It will also depend whether you run stock or mod. All electronic components can be mounted in such way that influence on flex is very small, so the chassis and topdeck can do the “work “. Serpent offers the suspension arms in v2 hard and medium. Mostly used now is v2 hard, but medium may work well in some lower grip conditions as well.

Q: In the list of specs I see that a lot of attention went into weight reduction. The new lower brackets, alu trackrods and camberrods, lighter motormount, alu spool, composite anti-roll bar centerers. Is the ERYX 3.0 closer to the minimum weight and what results has it ?

A: For sure weight has a major influence on handling and performance, but more so the center of gravity. With the slightly higher weight of the alu chassis we put the weight as low as possible and tried to reduce it higher in the car. We wanted to make sure that you still can play with the seperate weights we offer to create the preferred balance.

Q: The ERYX 3.0 has the new version double joint cardan shafts as standard, that many drivers will like, can you explain again the main reason to use those and whats new on the v2 type ?

A: The double joint cardans are made in v2 type with clips instead of the shrinktube. Makes maintenance easier. The DJC’s prevent chatter, which may occur under high grip conditons and under close to full steering angles. They provide more turn-in and a much smoother steering. We had to put it into the kit because it was such a favourite item.

Q: The spool is now a version with blades . What is the key benefit ?

A: It’s a one pieces spool is lighter, hard anodised and has the drivecups integrated. The blades will increase lifespan a lot !

Q: I see that also the ERYX 3.0 has this cool looking servomount system. Can you explain the key benefits ?

A: The servo mount is connected to the mounts which also hold the steering system in place. Its mounted basically in the centerline of the chassis, so no negative flex influence. In this way very few parts are needed, and the center of gravity is as low as possible.

Q: the ERYX 3.0 has all the new V2 hard suspension parts inside, what is the main reason for that ? and why the new shockmount position and mount the anti-rollbar in front of the rear arm ?

A: The hard suspension arms give the best performance, so the shocks, springs and anti-roll bars, combined with chassis-flex can be used to the max. The new position of the shock was a request of a lot of drivers who felt that the older two position where either to far in or to far out. We think that the new center lower shock position gives more grip. Same with the new rear anti-roll bar mounting position.

Thanks for the interview and giving insights in the development and why’s of the news.

C'est exactement ce que je pense depuis l'annonce, comme sur les 710 et NTC3 (entre autres) ça n'a jamais vraiment marché, ni été catastrophique. Je me réjouis de voir le truc.

Ma BMT avait deja ca en 95, et si mes souvenirs sont bons mes SST aussi... je ne comprends pas pourquoi ce n'est pas plus repandu, il doit bien y avoir moyen de trouver le sweet spot. A mon avis papy Salven est la bonne personne pour le faire marcher en 2014 ;) Me rejouis!

Parce que si tu mets trop de variation en virage ça génére aussi du bumpsteer en ligne droite et ça peu vite devenir compliqué ! (c'est ce qu'on trouve sur vos vénérables ancêtre mais aussi la problematix).

S'ils ont un système qui réagit par l'effort latéral transmis par le pneu et non par le déplacement vertical de la roue, là il y aura innovation...

Moi j'dis ça, j'dis rien !

MDR, c'est exactement cela... back to the future

Pour info, bien avant la BMT active, il y avait cela sur des buggy Nichimo 1/10 genre 1985~1987; et probablement d'autres.

-J'imagine à peine les prises de tête que cela va créer pour ceux qui ne maîtrisent pas le réglage.

-J'imagine par contre très bien le jeu et surtout les angles néfastes que cela va prendre sous les gros efforts.

J'espérai un truc plus novateur, comme par exemple un axe de bras outboard non parallèle à l'axe inboard, comme inventé par Eric Birrer au début des années 90 et très vite copié (dans le mois suivant le chpt d'europe lors duquel Eric a roulé avec) par Schumacher à l'avant de son 2WD ("SACHS" ou un nom du genre).

La RC, c'est un éternel recommencement: --> retour au diff à pignon --> retour au châssis alu --> retour à la suspension active et bientôt quoi ? moteur à charbon ? vario mécanique ? ^^
