Tamiya Mini Rules

General

It is intended that this class be a lower cost fun class to attract new racers. For this reason the use of custom chassis’ which differ widely from the standard M Class chassis spec is specifically not allowed.

Any of the recognized Tamiya Hop Ups may be fitted either as Tamiya parts or as those manufactured in the style of Tamiya by the likes of 3 Racing, Yeah etc.

Ball Differentials may be fitted, but locked differentials are specifically banned.

If you use a gear diff, only use the grease that is supplied with the kit.  Other greases or oils are not allowed as they are more likely to leak on the carpet.

Motors

Any commercially available sealed can (non-rebuildable) brushed motor with no less than 20 turns.

Alternatively, the Hobbywing Combo-B1 brushless system may also be used.  Combo-B1 consists of the EZRUN-35A speed controller, the 13T@3000KV EZRUN-3650M brushless motor, and programming card.
