Performance Scale... luokka kaikille?
Lähetetty: Ke 05.12.2018 22:37
Jo keväällä heräsi pieni mielenkiinto Australiassa marraskuussa ajettujen Crawlereiden MM-kisojen lisäluokkaa kohtaan. Luokka vaikutti hyvinkin yksinkertaiselta ja toimivalta. Kyse oli 1.9” renkailla varustetusta scaleluokasta missä ajaminen ja auton suorituskyky oli pääosissa eikä niinkään scale pisteiden kerääminen. Nopealla vilkaisulla luokka vaikutti täydelliseltä “sisäänheitto” luokalta.
Autoksi kävi periaatteessa lähes mikä tahansa nykyisin kaupasta ostettava scaleauto varsin pienin muutoksin jos niihin edes oli tarvetta.
Maailmallakin on herännyt voimakasta kiinnostusta luokkaa kohtaan koska joka puolella maailmaa painitaan saman ongelman kanssa mistä saada lisää harrastajia niin crawling kuin scale puolellekin eli kilpailun aloituskynnystä pitää madaltaa.
Olemme hieman harkinneet ottavamme tämän luokan Suomen kisasarjan ohjelmaan mikäli kiinnostusta löytyy riittävästi. Tässä olisi nyt loistava tilaisuus ajaa kilpaa niin scalemiesten kuin crawlinghöpöjen kanssa samassa luokassa sekoitettuna sopivalla määrällä aloittelijoita taitojaan koetellen.
WRCCA:lla eli käytännössä crawling luokkien kattojärjestöllä on aikomus ottaa tämä luokka siipiensä suojaan. Eli hyvässä tapauksessa joka puolella maapalloa ajettaisiin samoilla säännöillä. Tämä tarkoittaa myös sitä että olisi ehkä mahdollisuus ajaa PM-kisoja ainakin kyseisen luokan kohdalla ehkä jopa muidenkin scale luokkien.
Facebookissa on tällä hetkellä kysely mitä luokan sääntöjä olisi tarve/halu muuttaa. Olemme jo alustavasti crawling porukan kanssa keskustelleet asiasta. Laiton liitteeksi sekä alkuperäiset säännöt, että omat “korjatut” säännöt mitkä ajattelin esitellä WRCCA:n väelle. Haluaisin nyt kuulla mielipiteitä ja mahdollisia korjausehdotuksia sääntöihin mikäli tarvetta ilmenee.
Pääajatus luokasta on tarjota hyvä trial kilpailusarja niin lähes täysin vakioautoille kuin myös sääntöjen “rajamailla” rakennetuille kulkineille. Tämä toki vaatii aika paljon ratojen rakentajilta sillä perusradan pitää olla ajettavissa lähes vakioautolla ja bonusporttien suoritettavissa kehittyneemmillä värkeillä. Ajo tapahtuu crawling säännöillä eli kyseessä on nimenomaan “ajettava” luokka. Vinssit, ajosillat ym jätetään varsinaisten scale luokkien harrastettaviksi.
Nyt on sanavapaa ja toivon että keskustelu käydään “vanhanaikaiseti” foorumilla mistä kaikki tieto on löydettävissä myös pitkän ajan kuluttua...

PERFORMANCE SCALE VEHICLE SPECS
WORLDS 2018*
1 General Specs
• 1.1 Vehicles should represent a vehicle that has been modified to become a capable trail rated rig and is not necessarily street legal.
• 1.2 Vehicles must run a minimum full body from the grill to the B-pillar. Wheel arches may be radius'ed or trimmed for clearance. Where the vehicle is run in a cab-only configuration any kind of rear body design is acceptable. Chassis must have frame or bar work, bare chassis and shock hops is not acceptable.
• 1.3 All vehicles shall have the motor, transmission, and electronics covered and hidden when viewed from above.
Removal of the roof is allowed so long as a roll cage/half interior is fitted.
• 1.4 The body must be (3"/76.42mm) longer than the wheelbase.
• 1.5 A front bumper is required and must be wider than the chassis. Bumpers that are moulded into the body qualify. Chassis mounted bumpers need to project forward at least 3mm past the body.
• 1.6 Sectioning or narrowing of the body is allowed from the A-Pillar Forward and the B-Pillar Backward. But the body must still follow reference 1.2 and 1.8.
• 1.7 Body / Cage work must be at least 4.5"/114mm minimum height.
• 1.8 The inner wall of front tyres, measured at the axle centre must be covered by bodywork when viewed from above at rest. Flares can be added to the body to obtain coverage.
• 1.9 Minimum body width is 5”/127mm at the A pillar.
2 Tyres/Wheels
• 2.1 Vehicles are limited to 1.9 inch wheels/rims or smaller at the bead surface. 122mm / 4.8" maximum external diameter. Tyre size will be determined by advertised manufacturer specs. (Tires without available specs will be measured off the truck as mounted on the wheel laid flat).
• 2.2 Modified tyres ARE ALLOWED so long as they meet the above specifications and start out with a commercially available 1.9 Tyre Tread Pattern.
• 2.3 Tyres MAY also be modified from other sized tires using ONLY a pliable rubber but must meet rule 2.1. Pin tyres are not permitted.
• 2.4 A maximum width of 50mm from side wall to side wall Tires without available specs will be measured off the truck as mounted on the wheel laid flat) See Rule 2.1
• 2.5 Siping, grooving, cutting and removal of lugs is allowed.
3 Drive train
• 3.1 Vehicles are limited to front wheel steering only.
• 3.2 Vehicles must be shaft driven only and powered by a single motor. No "Motor On Axle" (MOA) of any kind. Your axles must be driven by one transmission or transfer case and a minimum of two drive shafts . No separate throttle control of drive shafts or axles.
• 3.3 No front or rear digs are allowed. Drive may be disconnected from the front axle only (for example, shifting from 4WD to RWD), but locking of the free axle is not allowed.
4 Chassis
• 4.1 Vehicles must be built on a plate, C-channel, or tub style chassis. Chassis must extend in one continuous length from the front axle centreline to the B-pillar as defined by the body. TVP chassis are not permitted.
• 4.2 Vehicle wheelbase is to fit the dimensions of the body used. In the instance a tray back is fitted, the wheelbase will be approximately defined as between double the distance of the front axle to the A-pillar and double the distance of the front axle to the B-pillar.
• 4.3 Batteries must be mounted to the chassis.
• 4.4 The section of the chassis that counts as the one continuous length must also have the skid plate attached to it directly.
*Note: this is not an official WRCCA class, it is a special class to be run at 2018 WRCCA World Titles only.

Motor mount cannot be part of or directly coupled to an axle
• 3.3 No front or rear digs are allowed.

*Note: this is not an official version of the rules. The are just my vision how they should be.
I have tried to honnor the original rules and the spirit of the class. And not modify them too much.
I have regulated the rules litle bit more just to keep costs down and cars more simple.
Allso to help lower the step for the new commers to come to the class.
Hard front bumper with minimum width will even the differences of different body design styles.
The factory-made tire and the wheel/rimm rule will help the new commers and keep the costs down.
