Official Rules
ROCCK Racing
This class is intended to be a fun class for racers of all skill levels. To keep a level playing field, no performance upgrades are allowed to the truck. Only a few optional durability upgrades are allowed to the truck. Ideally, a Ready-To-Run Slash, with a transponder added, can win any Spec Slash race in the hands of the right driver.
Allowable Models: This class is open to any RTR 2wd (Brushed or Brushless) Traxxas Slash, as well the Traxxas Slash Unassembled Kit (58014-4).
Cheating: Cheating diminishes the joy of the class. Do not ruin it for other racers by being dishonest. If you are caught cheating, you will be banned from the class and likely from racing at ROCCK in the future.
Class Race Fee: $25
Definitions:
Kit – referencing original equipment contained in the original box that the vehicle was sold in. In its original factory form. Not aftermarket.
Aftermarket – not original equipment. Not offered as part of the original equipment line of parts, from the manufacturer.
Vehicle Modifications and Parts:
Body: All trucks must use a Traxxas SCT body. You may elect to purchase a clear body and supply your own paint scheme. That is permissible as long as it is a Traxxas brand body. Cutting holes in the body for airflow is not allowed. It is permissible to remove torn, or broken pieces of the body, to prevent cuts/physical harm to turn marshals.
Chassis: No modifications may be made to the chassis system. Vehicle must be raced in its stock form. No LCG chassis allowed.
Suspension: Both the front & the rear suspension systems must remain in stock form. Original Traxxas parts only. No aftermarket replacement components may be installed with the exception of placing the upper shock screws with longer screws and a nylon nut. This is allowed because the shock cap screw tends to get loose in the shock tower over time, and tends to back itself out. RPM rear hub carriers are allowed for durability improvements. Stock (kit) shock collars may be used to adjust ride height.
Legal Tuning Parts: Original Traxxas Kit Shock white Springs (#5857 front, #5858 rear) may be used. Shock Caps may be replaced with Alum Shock Cap #3767 (or any other related color). Shock oil may be changed for maintenance purposes.
Steering: No modifications may be made to the steering system. Original kit parts only. Traxxas metal gear conversion for the stock Traxxas servo is allowed. (See bottom of page for approved servos).
Bearings: Original Traxxas kit bearings are preferred, but any inexpensive bearings (less than a couple of dollars) may be used as normal wear and tear occurs. Ceramic bearings are not allowed. Keep it cheap, and keep it fun.
Electronics: Original RTR Kit electronics Speed Control XL-5, BL-2S, or HobbyWing Justock 13.5 combo & Servo (2075/2075x) only. You may run a receiver that is compatible with your race radio.
