The natural progression in TCS is to start in the Novice Spec GT class and work your way up as you gain skill and experience. As you become more proficient in the GT categories, it will also be possible to select other race classes that begin with higher degrees of skill and proficiency such as Formula One and 1/12 GT.

Expert: High degree of racing experience with excellent and dexterous driving abilities.

Advanced: Experienced racer with proficient driving abilities.

Intermediate: Some race experience with adequate driving ability.

Novice: Minimal racing experience, early stages of driving development.

Classes

Note: Full factory sponsored and professional drivers should read below, as they are not eligible to participate in the TCS series.

“Factory Team” drivers (drivers who are, or have ever been, employed or supported by a factory, manufacture or distributor as part of a factory racing team) are not allowed to compete in the Tamiya Championship Series. Individuals that received or receive sponsorship entailing a monthly salary from a factory/manufacture and received paid airfare/accommodations to racing events are also excluded from TCS. TCS regional host sites and Tamiya America will do their best to exclude professionals and semi-professional individuals. If the host site deems it necessary, they may also bar those drivers who receive partial sponsorship. It is further at the discretion of the host site to determine which racers fall under the criteria and definition of “factory/sponsored driver”. Tamiya America cannot possibly know every individuals claims of who is or isn’t a sponsored or factory driver and therefore relies on the judgment and discretion of the host site to weed out the factory/sponsored driver that does not meet the average hobbyist criteria.

Note for Host Sites: Host sites must be careful not to confuse racers who get a deal from their friends that are employed or work for “motors R us” or get a discount at their local hobby shop. There will always be racers/hobbyists that will try and get a deal of some kind. Tamiya America strives for balanced conditions wherever possible.

Marc Rheinard, David Jun and Viktor Wilke are prime examples of racers that Tamiya America would not allow to compete. These individuals are clearly supported by a factory and would not be eligible to compete as Tamiya America supports their racing careers in all of the above mentioned points. Individuals that have 50% discounts from manufactures and distributors as part of a support factory team are also banned from TCS.

Past TCS Winning Champions: Racers that have won the “GRAND” prize (a.k.a. TCS National title) ARE eligible to participate in regular season TCS races. They are also eligible to win the first place trophy at these regional races; however they are not eligible to win the prizes that are associated with first place. In turn, we ask past champions to donate their first place prize to any participant or spectator of their choice. All former TCS national title winners that won the trip to Japan are eligible to participate at the TCS North American Finals under the “Past Champions” grudge match class and any special classes that are developed. National title winners that did not win a trip to Japan are eligible to compete again at the Nationals in a trip winning class.

CHASSIS

8. The use of thin shims (available at most hobby stores and made available by Tamiya) to space out the slop or play in suspension arms, steering bell-cranks and wheel axles is permitted in all vehicles except in the spec class.

18. LIPO TECH rule: In the interest of safety and fairness, all LIPO batteries will be volt metered at TECH prior to a “race or qualifying” heat. LIPO batteries exceeding 8.44 volts will not be allowed to race on the track until they have been discharged to meet the 8.44 rule.
19. Any battery connector or direct hard wiring to the battery is allowed.

Measured once only, 10 minutes after the race or sooner after the race heat or main, using the Tamiya, Much More or Peak motor checker in “step mode” (7.2V) for 22 seconds. The top 3 of each Qualifying or Main race will have their motors’ MAX RPM checked at the discretion of the race director or lead tech official. The car can not be taken back to the pits when selected for motor rules conformity. If the motors’ MAX RPM exceeds the set limits, penalties such as disqualification of times will be given. Please note that the motor will be hot after running and will thus have 200-300 higher RPM. Adjust your break-in methods accordingly to conform to the rules and measurement method!!

30. Tire conditioners are allowed on rubber/foam tires in all classes, but may be restricted at certain venues. (Some TCS host sites do not allow additives due to ventilation issues) Tires may not enter the TECH inspection area in a wet condition.
