R/C Car Racing

2017 Club Rules

 

Although the Ground Pounder Club is ROAR sanctioned, and all racers must be ROAR members to race, we do have Club Rules that we enforce at our events.  

 

Driver Etiquette: It is expected at our club races that drivers conduct themselves on and off the track with respect for other people’s equipment. Drivers should not intentionally make contact with another driver’s car. If it is done accidentally, the position should be forfeited back to the other driver. We expect our drivers to race cleanly and fairly. Ruff driving will not be tolerated.

 

CLASS RULES:  


Batteries: Depending on the class, any ROAR approved six (6) cell, or four (4) cell, NiCAD, NiMH or 3.7v and 7.4v LiPo battery packs, may be used. Batteries must be readily available to all racers. LiPo’s are used in most classes. Only Roar approved, hard cased, LiPo’s will be allowed. Racers are responsible for the proper handling, charging, and usage of their batteries. All Lipo’s must be charged in a “LiPo Sack” and must not exceed 8.45 volts after charging. For more info, and approval lists, please see Roar’s webpage www.roarracing.com  


Brushless motors: Must be Roar approved and on the most current Roar list. 

 

Exhibition Classes: If people have an idea for an exhibition class they would like to run this season for one race day they should bring the topic up to the board and then it will be discussed and voted upon at a general meeting.  If approved, the club will work the exhibition class in to the race schedule for an upcoming race day. 

 

Four to make a class clarification: There has been a slight misinterpretation of this rule the last few years, so we thought it best to clarify at the beginning of the race season.  “Four to make a class” refers only to the established classes already approved by the club for our normal race days (this goes along with the exhibition class notes.)  If there are approved upon classes on race day that have less than 4 cars sign up the board members will make the determination of how to handle the class (allow them to run or cut the race from that day.)

Race day entries: The board has decided to allow up to three entries per participant on a race day as long as corner marshal responsibilities are being handled.  It is up to the club member to arrange for this coverage. 

Heat and Main Race lengths for each class will be determined by the Race Director the day of each race unless specified below.


Novice Electric Road Course and Novice Electric Oval Classes: These classes are for beginning R/C Racers, most everyone will begin their racing career in a Novice Class.  No matter what type of car or truck you have, Novice Classes race them all together.  Novice Road Course will race the on-road track and Novice Oval will race on the Oval track. After a driver becomes better at controlling his or her vehicle, they will be moved out of this class and into a regular stock class for their car or truck. The Race Director has the final word on who can or cannot move up. Novice Class runs six cell batteries, or LiPo, stock motors or  BL 17.5, 21.5 and 25.5 motors.

 

Speed is not the issue in any Novice Class. Learning to drive a car or truck competitively on the race track, during a race, is what you should be after. Learning to have good control over your vehicle is a must in racing and a Novice Class is the most forgiving place to learn it. If you have any problems or questions, don't hesitate to ask other racers or the Race Director.  


17.5NR Sedan: This class is for the all Sedan drivers, giving everyone a class to race in while gaining track time and experience.
