Draft Rules – discuss options in our Forum 

F1, (Formula One) is one of the most exciting motorsports, with a level of international recognition like the World Cup, Tour de-France, Olympics and British Open. It’s ancestry starts back in the 1920s as one of the European Grand Prix races, and it’s legacy of surviving world wars, pandemics etc. hints at it’s popularity. Versions of F1 GP racing paralleled the early racing scene in America during the 20s-40s, with both continents fielding race specific manufacturers, as well as being showcases for the performance capabilities of some consumer brands.  The modern incarnation of F1 rules and technology were spawned in 1946-47 period, when rules were defined that allowed large-displacement (> 4 liter) naturally-aspirated engines to compete against small-displacement (< 2 liter) supercharged engines. The cigar-shaped open-wheeled bodies were adopted by Indy-500 teams, and the two have somewhat paralleled each other ever since, sometimes inspiring hot racers to cross continents and technology (not with guaranteed success!)  With a total of ten international teams and therefore only twenty drivers(!) per year, the competition in both driver skill and technology is at an intense level. In the last few decades the engineering specs have become more stringent, and although engine technology is constrained by source (tends to be two) and modifications prohibited, the remaining components of the cars are often built in-house by the “manufacturers”, although they must past stringent technical specifications.

ASCC’s 2021 series celebrates an exciting period from 1986-89 when aerodynamics and power systems were bound by a range of options in an effort to increase competitiveness by reducing technology options and hence wild investments that resulted in “pricing-out” smaller privateers; while also decreasing safety risks from experimental technologies. This period was dominated by Williams and featuring legends such as Ayrton Senna, Keke Rosberg, Gerhard Berger, Alain Prost, Nelson Piquet, Nigel Mansell, Teo Fabi and others.

Austin Slot Car Club has dabbled in Formula series in the past, most notably in 2011 with a Scalextric box-stock series that proved a supreme challenge (even after expert tuning, the cars had unpredictable handling, and suffered damage to the spindly suspension, motors and other “detail” parts.) More successful series were held in 2015-16, based on the AllSlot generic, early 2000s format, formula cars; first with the fragile ABS chassis, followed in 2016 using the aluminum and carbon-fibre hybrid chassis (no longer available) from SVQ Slot.  An exciting option for the 2021 series is a set of accurate 1/32 scale helmets featuring many of the 1986-89 legends and even recent stars!
