Racing Info
Track Guidelines
​
-
Pay for practice or racing before getting onto the driver's stand.
-
Never stop your car on a straightaway or any other section that will impede other drivers. Pull off to an area that is well outside the racing line.
-
Always be respectful of your fellow drivers. Even if they are new and may not have the skills and control you have with your cars.
-
We are a family-friendly facility, and expect people to keep that in mind and keep their discussions respectful of that.
-
Cars have the right of way, and drivers may not see you. If you are marshaling or walking across the track, check for oncoming cars before stepping onto the track.
-
Call out your crashes. If you crash anywhere that may result in other drivers colliding with you, loudly and clearly announce where you have crashed so that to your fellow drivers so they can avoid an incident. This is especially important in high speed areas such as a straightaway.
-
Clean up after yourself when you leave, so your pit area is ready for the next driver.
-
Do not block aisles with your pit bags or chairs.
-
Cars are limited to 1/10th scale or smaller, with a maximum of 2S LiPo batteries.
-
Take a turn marshaling now and then when you are practicing. It can make everyone's else's practice session more efficient and enjoyable.
-
The purpose of this hobby is to have fun, so please relax and put that first.
​
Race Rules and Etiquette
​
-
Marshal immediately following your race/qualifier. If you have back-to-back races or a physical limitation, you are responsible for finding a substitute marshal. You should only take the time to drop your car and radio off and get back to the track immediately.
-
Sign up as early as possible. Signups typically close 30 minutes before the race begins. Late signups can cause numerous issues for the race director who is configuring the heats.
-
Do not yell at marshals. If they are not paying attention and are ignoring your crashed car, respectfully raise your voice to get their attention.
-
Respect that your fellow drivers are trying to concentrate during a race, so regardless of what happens to you or your car, refrain from yelling, obstructing other drivers' views, excessive talking, stomping off the drivers stand, etc.
-
If you cause another car to crash, wait for them to pass you before you resume driving.
-
Give space to any driver who has lapped you, and allow them to pass. Do not try to race with them.
-
During IFMAR qualifying where each driver is on their own clock, allow other drivers space. You are not racing head to head for position, so it's best to allow other drivers room to drive their line.
-
Using reverse is not allowed during a race. Wait for a marshal to help you if your car is face-first against an obstacle.
​
Marshaling
​
-
Pay attention to the area you need to marshal and be ready for any incidents that may occur there. Do not get distracted watching the race.
-
Carefully place cars on their wheels, facing in the correct direction.
-
Do not place a car in front of oncoming traffic.
-
Do not step in front of cars who are still racing. Causing a crash of an innocent driver is much worse than taking another second before marshaling someone who already crashed.
-
If a car breaks during a race, place it upside-down outside the race lanes and resume marshaling.
-
First in, first out. Marshal cars in the order in which they crashed, as this is the most fair approach. (during practice, this is not required, and you can just marshal in the order of who is closest to you)
-
If a car crashes off the track, return it to the spot where it crashed, when practical. Do not skip a section of the track to help compensate the driver for lost time.
-
Don't place a car on the take-off of a jump if doing so will make it difficult for the car to clear the jump.
-
Be aware of the danger involved in marshaling. If a young child wants to marshal, make sure they have guidance regarding how to do so safely and effectively.
