S32 American Thunder
American Thunder I
This event focuses on North American automotive and racing history and overlaps with several R32 classes: Hot Rod (HR) including Street Rod (SR), Rat Rod (RR), Street Machines (SM) and Gasser (GS); Boulevard Cruiser (BC); Indy Roadster (IR); Trans Am Plus (TA+) and CAN AM (CA) but limits models to those that are scratch built only.
Our current definition of scratch built is very wide and casts a large net (many would argue too large) to include any model for which at minimum either the body or the chassis is prepared by the builder.
Ready to run white kits are ineligible. Mating a RTR/production chassis to a different RTR/production/pre-painted body also falls short of the mark. If you are unsure, please ask.
To qualify as scratch built all models must be ‘one of a kind’ meaning that they must be unique, regardless of whether they were made by the builder or bought second hand. Liveries need not be unique but the model as a whole must be.
Our emphasis is on encouraging and promoting scratch building above all other aspects of this hobby. Participation is essential and while we all strive for quality and performance in the models we make we must never discourage, deter or frustrate the efforts of any participant. To promote participation and a grid of diverse models some classes may focus on originality and attention to detail/quality over performance.
Both historically accurate liveries and period correct fantasy liveries are strongly encouraged.
Overall completeness for all scratch built models is essential and includes:
- appropriate racing numbers (where expected or required)
- period wheel detail including painted inserts
- interior detail with painted pilot/co-pilot (if applicable) detail
- appropriate exhaust and mirror detail
Building and presenting up to three models per class is encouraged and those that do will have an opportunity to race them each as a separately scored entry – time or rotation constraints may limit the number of allowed entries per person though.
Do not be discouraged from participating if you do not have an eligible model for some or many classes… because one day you will! And remember, every model that participates in this event whether in person or by proxy will be entered into our Scratch32 database and will have its own gallery in our models gallery area.
Hot Rod (HR)
Sub-Classes: Street Rod (SR), Rat Rod (RR), Street Machine (SM) & Gasser (GS)
Sub-classes will be scored separately. Limit of three Hot Rod (HR) entries per builder regardless of sub-class.
- Street Rods (SR) – (aka Hot Rod) – Any modified or customized car or truck model from 1948 or earlier with or without fenders in paint or in primer;
- Rat Rods (RR) – Any custom car or truck model with a deliberately worn-down, unfinished appearance, typically lacking paint, showing rust, and made from cheap or cast-off parts;
- Street Machines (SM) – Any modified or customized car or truck model from 1949 or later with fenders in paint or in primer; and
- Gassers (GS) – A vintage drag car that was popularized in the ’50s and ’60s (up to 1968) that ran on gasoline and used a straight axle front suspension which gave the model a very high front end stance. Most gassers also sported Halibrand wheels, no front bumper, and had a front mounted Moon tank. The gasser form was dictated by function and most builders looked to eliminate as much weight as possible. Having their exhaust pipes exit through the front fender to shorten the length of exhaust tubing is another common characteristic of gassers. Builders used 1930s through 1950s production coupes or sedans to create these highly modified racing vehicles, including (but not limited to) the following: 1933 Willys Model 77 Coupe; 1940 Willys; 1941 Willys Americar; 1948 Anglia; 1949 Chevy Fleetline or Styleline; 1951 Henry J; 1955 Ford T-Bird; 1955 Chevy Nomad; 1955 Chevy; 1957 Corvette.
