At Coastal RC, the track surface is CRC black carpet, so there's no shortage of traction. There's a distinct lack of dirt, but the jumps won't leave any doubt what Off Road racing is all about on the 88 x 52FT surface that sees a regular rotation of layout and jump features.
Buggies are quick, light, and fast reacting, with narrow tires, minimal bodies, and the signature wing finish the iconic open wheel look. Available in 2WD and 4WD varieties, racing in separate classes, buggies are an off-road staple class and a crowd pleaser.
Stadium trucks are the slightly wider, larger tired cousin to Buggies. Still open wheel, but no wing, and a larger coverage body. Stadium trucks are a little easier to drive, but that doesn't make the racing less exciting.
Short Course Trucks look like the full size thing. Full coverage bodies that cover the wheels and tires allow for real "fender rubbing" contact racing, while "under the lid" you have the tunability of a stadium truck.
The Traxxas truck that kicked off the Short Course class. This class is about getting started racing with minimal starting cost against others with identical equipment.
What is Stock? Short answer: a motor type/wind has been identified for the class.
Modified: you can run as fast of a motor as you want.
In many cases, there could be a stock and modified class for each chassis type.
Rules can be a bummer, but racing on a "level field" is hopefully enough reward to get through this bit.
