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 or Mardave manufacturers spec are specifically not allowed. As an example a modification to the chassis to either add or remove material to enable the secure fitting of Lipo batteries is allowed and this may extend as far as widening the standard Mardave chassis or replacing the lower (main chassis) with one shaped specifically to allow Lipo mounting. However, the addition of shock absorbers, suspension modifications and the addition of other tie rods that are not available on the kit versions or  as recognized upgrades are not allowed.

In the case of Tamiya cars 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 to either car but locked differentials are specifically banned on Tamiya cars.
