I collected a couple complete rollers of the Serpent 2wd Impact, but have lost interest in them. I got solid, ball, and slipper diffs for them, as well. PM me, if someone would like to help me clear off my shelves.

Hi,

I have copied the french specs rules for " Classiques" or 1/8 flat chassis.
The initial rules are the same that 1/8.

Source FVRC

2.2.3 Catégorie CLASSIQUE :
• 4 roues.
• Propulsion par les roues arrières.
• Pas de transmission a rapport variable (Boite de vitesse,
…).
• Différentiel autobloquant ou de type TORSEN interdit.
• Châssis monobloc sans articulation, pouvant être
constitué de plusieurs éléments fixés solidairement entre
eux et formant un ensemble non déformable, hormis la
flexibilité naturelle des matériaux.
• Pas de roues indépendantes :
Pas de déplacement relatif entre les roues d’un
même train en dehors de l’effet de braquage.
train en dehors de l’effet de braquage.
Les paliers d’un même train (avant où arrière)
doivent être fixés sur un même élément (plaque articulée
où châssis).
En cas de train arrière articulé, les paliers de
l'axe d'entraînement dynamique des roues motrices
doivent être fixé sur un même élément.
• Les réglages de pincement, de carrossage, et de voie
sont autorisés sur toutes les roues, mais doivent rester
constant en fonctionnement.
• L’utilisation de cardans est acceptée.
• Pas d’amortisseur ou de quelconque systèmes flexibles
sur le châssis lui même, seule la possibilité d’un élément
support de train avant où arrière articulé en 3 points
maximum est autorisé.
• Pas de suspensions, même bloquées.
• En cas d’utilisation de fusées leurs fixations doivent êtres
assurées par (au moins) un palier solidaire de l’élément
support de train (Av ou Arr.)
• Poids minimum : 2300 grammes (sans transpondeur et
réservoir vide).


Some points have been added since 2 years because a french manufacturer ( Contact 300) has created a new car that has imposed new questions.

To see on my website,

A thread on the Motonica

The same about the WRC GT DUE

Un small thread about the DXF


The BRX 4 REDBALL
This car ...the BRX is another french car made by Eric LECOUR.
You'll find on his website more about the BRX4, or the Intrepid from Mantua, Information about a first price car the SUPER AVANT

This last car from Mantua was their first new flat chassis before the Intrepid.
The old racers will recognize the SG VCS from Mister SABBATINI.
Normal... Mantua has bought the parts models

About all the flat chassis story,Thierry SIMON has made a very big work to read ....


Hope to help You

Nice links in the above post. Some of these cars look really cool.

Rockets might actually refer to the pivot balls.

Hi,

About the special point "rockets",

The Contact 300 was a flat chassis but has shown a failure in the rules.
All seemed rigid but it could have deformation on rear in fact.

It was very ingenious.
This car has been stopped and now it's the Contact 310.

But Rules keep eyes on this point.

The Contact 300



You'll find all on RC CONTACT

then " Nos réalisations"

then " Plus d'infos ici"


The spec ......... the Flex system

Ce qui a motivé le développement de cette auto est principalement la volonté d'intégrer un système innovant dénommé "flex" dont le principe était de permettre au chassis de se déformer sur toute sa longueur, y compris sous le moteur. Cela devait permettre au train arrière (parfaitement rigide et fixé sur le chassis), de rester "collé dans les courbes en dépit de l'effet de la force centrifuge.

Ce principe ayant été jugé "limite" du point de vue du règlement, il a été mis de coté pour l'instant afin d'éviter toute discussion en attendant que le règlement soit rédigé de manière plus précise.

Le système "flex" a donc été supprimé sur toutes les autos du team avant la première manche du CF de Lentilly.


So

What motivated the development of this automobile is mainly the will to integrate(join) a called(mentioned) innovative " flex " system the principle of which was to allow the chassis to deform on all its length, including under the engine. It had to allow the back train (perfectly stiff and fixed to the chassis), to remain " stuck in curves in spite of the effect of the centrifugal force.

This principle having been judged "limits" from the point of view of the regulation(payment), it was put of quoted(esteemed) at the moment to avoid any discussion until the regulation(payment) is drafted in a more precise way.

The system " flex " was thus eliminated on all the automobiles of the team before the first sleeve of CF of Lentilly.




With the new rule of the FVRC, The Contact 310 comes.

This one hasn't got the flex system

The Contact 310

Judge,

Thank you for the Information you posted. We are trying to get the "classic" cars running in this country. There seems to be some interest. Thanks again for sharing you knowledge of this class.I will receive a DFX Vortex and the Motonica P8C this week. I am going to build both cars as a comparison.

Sorry I have not found this earlier, I am usually on the european forums. But just FYI, I am trying to get a WRC through Italy and the quote was 410 euro.

Default 1/8 Pan Cars... back to basics

My name is Danny Alvarado and I don't think there is a more appropriate time for a resurgence in 1/8 pan car racing than now. I see a few good reasons for why but the ones that stand out are lowered cost and simplicity.

Written earlier in a previous posting was how do not shoot ourselves in the foot again. I believe this was in reference to the loss of the 235 class due to a change in rules and the increase in expense that came with the new rules. I have to say and this is only my two cents, that if this class is to grow and have longevity, that the rules must be written with the idea that it must remain consistently cost effective with little or no deviation.

I have been a huge fan of 1/8 on road since 1979. I have seen the class grow and later shrink over the years. I always felt that this class needed an entry level class. Looking back over the history of 1/8, you will find that there was always an 1/8 class that fed the next generation of technology. Begining with pan cars progressing to 2WD suspension cars then to 4WD. In 1990, as the popularity of 1/8 declining in the late eighties and early nineties I was excited to learn that Serpent would be producing a 1/10 or 235 chassis. I thought that this would be an easier class to promote as far as expenses were concerned and the skill required to drive one. I believe that this may actually have worked and may have been a "feeder class" to 1/8 as the years went by. However, we all know what happened to that class. That being said, I would love nothing more than to see a resurgence of 1/8 pan car racing. I think it should be embraced as a class all it's own and as time goes on it may help to feed the 4WD class. I am looking to it as more of an entry level class. A car and type of racing that will help to promote 1/8 racing and most importantly, draw new blood into the sport.

One thing that I would like to add to the rules mock up would be that the engines should be kept stock. Knowing racers, they will seek out every edge possble including engine mods. That might only encourage others to spend extra money to "keep up". Keep the rules simple and with little deviation, I hope, might lead to growth and longevity for this class. I have an RC 300 BD and will look into getting it together to go out and try soon.
