The Barn Raceway
Racing at The Barn Raceway is meant to be fun! It’s also meant to be enjoyed by the entire family. We will strictly enforce our “attitude” rules. Our drivers have voted on a $5.00 “guilty” penalty for the upcoming winter season. If you shout out from the podium, address a turn marshall or competitor in a less than respectful manner, etc. – you will incur a $5 “fine” that will go toward the drivers point fund and/or future special events prizes. If you incur a fine, you will not be permitted to compete again until your fine has been paid. Although this is meant to be a lighthearted way of addressing the problem, we will take it very seriously. We expect our racers to treat others with respect and remember that our track is meant for one thing – fun! We appreciate our racers volunteering this rule as a means to make a positive outcome from a broken rule.
-No reverse in any class other than the novice class. The penalty for reverse is one lap from your current race and a stop and go penalty for your next race. If you have a problem with remembering not to use reverse – program it out of your ESC! - Any tire additives that are used must be wiped clean from the tires before any races or practice sessions. -All racers are responsible for turn marshalling the race following their own. If you are physically or otherwise unable to turn marshall – it is STILL your responsibility to find someone to fill your position. Races will begin at no longer than 2:30 intervals if you are not in position to turn marshall the following race, you will be assessed a stop and go penalty in the following round. You will also be deducted one lap in your next race. - Turn marshals may not work on or repair cars during a race. Turn marshalls must be 16 years of age or have been approved by the race director. Prior experience for those under the age limit will be considered. - All cars must be made available before and after races for tech inspections. Once a car has gone through tech before the race it must go directly to the track and not to pit area. Any time that your car is deemed illegal in tech, you will be moved to the last qualifying position for the following round. If you are found illegal during the rounds of mains, you will be scored last in your respective class. You may not continue to race until your car has been passed by tech. - Cars must enter and exit in designated areas of the track only (turns 1 and 4). -The race tone will sound at no longer than 2:30 following the previous race. If your car is not in position on the race track at the 2:20 mark, your car will forfeit for that round. There will be no heating/heat sources of batteries, tires, etc. inside or at our facility. We will ban any such items that may be a safety risk. Race directors will have ultimate authority over rules enforcement. The primary basis for any rules decision must be based on what will be best for the majority of racers. If an item is not addressed in the rules listed here then you should assume it is not legal.
4 cars may be considered as a minimum to run a class. Classes with less than full fields may race a limited schedule. Having 4 or more of a class that is not on our class list does not mean that we will race that class.
The RC Dirt Oval scene is an ever changing dynamic. We welcome changes, but also realize that there needs to be a reasonable progression for allowing/adopting new rules, new products, etc. into our racing program. New rules are typically announced months in advance of them taking effect. Similarly, new chassis kits/conversions, newly unveiled products, etc. are welcome at our track. As a general rule, we adopt all products as "legal" once they have been in production and available to the general public for two months or more. This allows everyone an equal opportunity to compete with those new products.
