Classes
The Track
The Track
Oval cars are usually, but not always, pan cars (or some variation) with a solid rear axle. Sometimes touring or buggy chassis can be converted (with a body change) to create a visually striking oval class.
The largest differentiations from one pan car class to the next is in body, tire, and motor specifications.
Oval "weekly" classes

NOTE: This class will run on a reduced "footprint" track better suited to the vehicle size, not the full 1/10 oval.
The following is the suggested race format from the 1RC rules for reference, and is NOT NECESSARILY INDICATIVE OF HOW RACING AT COASTAL RC WILL BE CONDUCTED FOR THIS CLASS: Suggested Race Format
As more racers are starting to build tracks, we have had a lot of requests to come up with a general race format for tracks to use. Below is a race format we have used in the past that works well. This format provides you a lot of wheel time and allows for you to have a bad heat race or two but not ruin your whole day of racing.
Qualifying
- Each car will get four (4) qualifying laps. Your fastest lap is your qualifying lap and is how you are seeded into the heat races.
Heat Races
- Based on your qualifying time, you will be grouped into heat races consisting of 5-6 cars.
- Heat races are 10 laps in length and you will run 4 complete heat races.
- In the first round of heat races the lineup is inverted, fastest car in the back, slowest in the front. In the 2nd heat race, the line up is inverted from the order of finish from your first heat race and so for the remaining heat races.
Main Events
- Main events are sorted into 5-6 car races and your main event position is determined by your fastest 10 lap heat race finish.
- The lowest main event will run first.
- Starting position B-Mains and lower are heads up, the fastest car in that main event starts in the front. The A-Main will be a draw to see how many rows are inverted.
- Laps for main events are as follows:
- A-Main - 50 Laps
- B-Main - 40 Laps
- C-Main - 30 Laps
- D-Main and Lower - 20 Laps
- Top finisher from each main event will bump to the back of the next higher main event.
Re-Run
- Once the entire race program above is completed, you will run this entire program again as many times as you have time to complete.
As mentioned, this is only a suggested format but it works great and provides you a lot of racing. This format allows you to have a bad heat race or two and not ruin your whole night of racing. The most important thing with any race program is to have fun and that is what these cars are all about.
