Reigning 1:10 200mm World Champions Infinity have released a new version B clutch weight for their IF15 kit. These innovative clutch weights sit between the flywheel pins and offer a higher clutch meet than the normal type weights making them suitable for use with basic engines such as O.S. 12TG . Set screws are included to adjust the weight and clutch meet pressure. The version B weights are also usable with high power engines.
