Practice

• Practice will be separated by like speed classes. Rocky Mountain Spec - F1, Stock - 3500 GT, LMP/LMH - Mod AWD, Mod GT, Mod Open
• Practice will be 3:00 sessions with 30 second driver transition time, session time is dependent on time constraints.
• No more than 10 drivers on the stand per practice session.
• The number of practice sessions each class gets will be determined by the number of entries per class. For example, if there’s 27 entries in Stock and 15 entries in F1, there will be 5 sessions of practice to allow every driver in those classes an opportunity to get a practice session in.

Qualifying

• There will be a Pre-Qualifier plus three qualifying runs (Q1, Q2, Q3) for each class. Depending on entries and time constraints a 4th qualifier (Q4) may be added. The race director will decide that before the event starts.
• Pre-Qualifier will last for 3 minutes, Q1, Q2, Q3, and Q4 rounds will last 5 minutes with 1 min warm-up and 30 second driver transition time.
• All Qualifying rounds, the drivers will be called out individually to start, and will be on their own clock (IFMAR qualifying).
• For the Pre-Qualifier run, the starting grid will be randomly sorted. Your top 3 consecutive laps will count towards the sorting order for Q1.
• The 1st – 4th qualifying rounds will be resorted by your best laps and time result from all qualifiers to that point.
• There will be only 1 racers minute allowed per race if needed, racers minute will last a maximum of 1 min. The track will be closed during the racers’ minute.
• The racer’s final qualifying position will be based on your best single qualifying run, laps and times of the 4 qualifying rounds. TQ will be awarded to the racer with the best laps and time from a single round (Rocket Round).

Mains

All Mains

• The winner of each main will score: 1 point, 2nd place will score: 2 points, 3rd place will score: 3 points, and so on, scoring one point less for each driver down to the last finishing position. If a driver does not start a main, they receive 14 points.
• 2 turn rule - there will be no passing in the first 2 turns of any main unless a driver wrecks in front of you.
• There will be only 1 racers minute allowed per main if needed, racers minute will last a maximum of 1 min. The track will be closed during the racers’ minute.

A-Mains

• All “A” mains will run 3 times for 6 minutes using a point system to determine your final position. Your best 2 finishes of the 3 “A” mains will count towards your final points. Least number of points wins.
• All “A” mains will be 10 drivers maximum.
• A driver who wins the first two mains of a triple A-Main event must sit out the third main.
• The “A” mains tiebreaker is the best single finishing position (1-3 beats a 2-2) If there’s still a tie then the best Laps/time from the best finishing position run is the final tie breaker (IFMAR).

Lower Mains

• All lower mains will run 2 times for 6 minutes using a point system to determine your final position.
• No bumps from the lower mains to the “A”.
• lower mains 4 minimum, 13 maximum.
• The tiebreaker is whoever finishes higher in the 2nd main.

Classes

• 8 entries make a class, if 8 entries fail to sign up, the class will be dropped.
• Awards will not be ordered if we fail to get 8 entries signed up 2 weeks prior to the event but will be run if 8 entries show up the day of event.
• AAA Stock and LiPo Stock will be combined if not enough entries sign up for either of those classes.

The above list is non-comprehensive. The purpose and spirit of the rule are to allow functional performance modifications to the body while preserving the scale appearance and realism. The technical inspector has final authority in the judgment of body modification legality. If you have modified your body and have questions regarding the legality of the modifications, please submit the body in question to technical inspection PRIOR to racing qualification or main event rounds. This is to prevent any inadvertent disqualifications. The technical inspector will judge the legality of body modifications and photograph the body in its legal state if necessary.

If the body is further modified post-inspection, the modifications may or may not be legal. For the racer's protection, please re-submit the body in question to technical inspection IMMEDIATELY if significant modifications have been made. If the body is damaged, the condition of the body may or may not be legal. For the racer's protection, please submit the body in question to technical inspection IMMEDIATELY if significant damage occurs. If the damaged body is judged illegal, it must be repaired or replaced for the next qualification or main event round. Qualification or main event results during which racing damage occurs on track will be allowed, as long as the body is not judged to be intentionally designed to break away to benefit performance.

Lexan Bodies

Aftermarket Lexan, molded plastic, 3d printed, and carbon wings are allowed. Maximum wing size cannot be bigger than the original wing cutting line. The rear bumper may be removed up to a maximum of 20mm from the ground.

Because a body isn’t listed above doesn’t mean it’s not allowed. Check with the race director before the event to get a final answer on whether your particular body is allowed or not.

*Subject with Bodies Rule

Any production or 3D printed parts not publicly available before the start of an event, are considered prototype parts. Any new parts must be publicly announced via social media or website and be available for purchase on a national scale to be considered publicly available. 3D print files shared with the public 30 days before the start of an event, and can be printed by the public, will meet the requirement of being publicly available for that particular part.

• Proper manners and good sportsmanship are expected from all drivers at all times. It is important to understand that general bad behavior like cursing, intentional bad driving, etc. will not be accepted and can result in a driver being penalized, disqualified, or even asked to leave in extreme cases
• All participants will be expected to attend the drivers' meeting. Drivers will be expected to understand and comply with each rule by the time they leave the driver's meeting. Ask any questions at this time.
• If there is a rule dispute between drivers it must be brought to the attention of the race director or race personnel. The officials at the track will do their best to resolve any issue to the satisfaction of everyone.
• If a racer notices an illegal item on another racer's car. Please report to the race official after that racer's race, so the car can be inspected without interference.
• Substitute drivers are not allowed in any qualification or main event race. Immediate disqualification from the event for both drivers will result.

Motor tech procedures

All motors to be ran in AAA Stock, LiPo Stock, F1, LMP/Hypercar, and 3500 GT classes must be Pre-Event teched and marked for motor rule compliance.

• Motor must be unsoldered, and sensor wire removed before handing it over to the tech official
• The motor will be teched for Kv using a SkyRC Motor analyzer (SKY-500020)
• SkyRC Motor analyzer will be powered using a 72 watt variable power supply set to 8.4 Volts (SHNITPWR)
• SkrRC analyzer will be set to the first option, Kv analyzer, power knob will be turned to full throttle level (all lights lit)

Race Director or Technical inspector can tech any car at any time without reason.

Pre-Event is considered, any time prior to the first race of the event. Every driver can submit his car for pre-event tech to make sure they are in compliance with the rules. All Stock, F1, and 3500 GT entries must Pre-Event tech the following items, all motors, pinion gears, and spur gears to be ran in the event. Those items will be marked for easy Pre-Race tech.
