M-TC Rules & Guidelines 2021/22

Below are the current M-TC (Mini touring Car) Class rules.

Welcome to the M-TC.org.uk rules & guidelines update for the forthcoming 2021/22 season. The M-TC class of RC car racing is based upon the ethos of controlled and competitive sport. Since its inception in 2015 M-TC has been well suited to newcomers and experienced racers alike. Being of 1/12 scale it is particularly attractive to club racers where track size is often limited. In recent times there have been many new manufacturers bringing their M-TC offerings to the table. The variety of models means that M-TC has something to suit everyone in terms of price and specification. In these rules we have taken to limit items such as motors by specifying the actual make and model. There are restrictions on ESC’s in terms of the running mode and also of price. This approach ensures that all cars racing in the class will have remarkably similar amounts of power available irrespective of the cars brand, price or model.


Our goal with the following is to provide a framework for clubs who wish to run the M-TC format to base their rules upon. To that end we have kept them as straight forward and simple as possible.


M-TC.org.uk will run a “Clubmans” UK race series once we can return to some form of normality. In the meantime, we intend to offer our support to clubs and individual racers alike. Hope to see you all trackside soon.
