Roar amends electric chassis rule

Roar Racing

Electric chassis rule amendment – After careful consideration, the ROAR Committee has approved some new wording to clarify acceptable chassis configurations for electric racing after the release of a number of “short” battery packs. These packs are generally shorter than maximum length, which are completely legal, given that the rules only specify maximum dimensions for the battery packs. The risk, however, is that a chassis might be built around a short pack, which would be a very negative development in the opinion of the Executive committee. While some members of the electric committee preferred a different approach, it was the judgment of the Electric Section Chair and by a unanimous vote of the Executive Committee, that it would be more prudent to clarify this rule before it becomes an issue. Waiting until one or a few chassis are configured in such a manner would not be in the best interests of members who invest in these products, the manufacturers that make them, or retailers. In short, it would not be a benefit to anyone. It’s the position of the Executive Committee that it would be a costly and unpopular decision for all involved, to wait until after everyone has an investment in a chassis configuration that would ultimately be deemed not legal.
