Measured once, soon after the qualifying, or main race, using the Tamiya, Much More, or Peak Racing, motor checker in “step mode” (7.2V) for 22 seconds. The top 3 of each race will have their motors’ MAX RPM checked at the discretion of the race director. The car cannot 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: 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!!

7.8 Brushless motor classes: See class category specific rules for the legal motors that may be used for your entry.

7.9 Brushless motor rules: Tuning Rotors are legal in classes where a specific “spec” motor is not used.

(We want to encourage racers to get creative with any of the TCS race cars they own and show them off in Best of Show, regardless of what class they’re racing in for that event.)

9.8 As judges, we look at various aspects of the finished product. Individually, we will judge your car subjectively. We will be judging on, but not limited to, itemized categories as follows:

• Body trim-Quality of body trimming • Paint-How clean is the paint applied? Symmetry, clean lines, overall quality. • Wheel and tire details • Mirror & body accessory details • LED Light details • Livery-How well does the livery recreate a racecar, or theme? Replica, or fictitious? • Interior details-Does the car have an interior, LED lights, brake/exhaust. • Overall presentation

21.1 Former TCS “Ticket to Japan” winners must sit out competing in another “Ticket to Japan” class for 2 years before competing again in a “Ticket to Japan” class.

22.7 In the event that a “Ticket to Japan” winner is unable to attend the Tamiya World Championships, for any reason beyond the control of Tamiya America Inc., an alternate will NOT substitute. The class champion is considered a “Past Champion” in all future TCS events and must compete accordingly as such.

22.8 The 2025 TCS National Finals will follow the same regulations and class structure as the regional rules but will incorporate a few dynamic tweaks to the “Ticket to Japan” classes to tighten up fairness and bring something fun to one of the classes. A sneak preview to the 2025 National Finals can be viewed in November.

23.1 Added the Hobbywing FTM (Fixed Timing Motor) to the Spec Brushless motor rules for the GT-1, GT-2, GT-Pro Spec, and GT-E classes. In the mentioned classes, the HW FTM may be used in addition to the REEDY FT motor in 2025. The Reedy motor will eventually be phased out in the future.

23.5 Cleaned up and simplified some of the wording in the TCS National Finals eligibility rules.

23.6 Removed “the use of O-Rings” on shock ball ends and turn buckles in the General Rules. This former rule violates “build the car per the instruction manual” ethos. You may no longer use O-rings on ball ends.

23.7 Removed some redundant wording in some of the rules.

23.8 Added a TCS 2025 National Finals announcement regarding a few tweaks to the “Ticket to Japan” class regulations that will be taking place specifically for the FINALS.
