All radio control car-racing hobbyists are welcome to join the series. Whether you’re new to the sport or a seasoned racing hobbyist we invite you to partake in the Tamiya Championship Series where fun and good competitive racing is our top priority.

“Factory Team” drivers (drivers who are, or have ever been, employed or supported by a factory, manufacturer or distributor as part of a factory racing team) are not allowed to compete for prizes or awards. This includes drivers that received sponsorship that entailed a monthly salary from a factory and received paid airfare/accommodations to racing events.

There will always be racers who will try and get a deal of some kind. This cannot be avoided and therefore we ask for a balance as much as possible. The hardcore factory sponsored driver may not participate. An example of racers that Tamiya Canada would not allow to compete would be Marc Rheinard or Keven Herbert. These types of drivers are clearly supported by a factory and would not be eligible.
