Bezerk RC upgrade for Schumacher TOPCAT offroad buggy. Design with Craig Langman to replace the more fragile plastic counterpart (U7554), these are machined down from a 6.0mm thick piece of carbon. It has integrated gussets on each side to minimise the flex. Two 0.5 and two 1.0mm shims are provided to make up the overall thickness and allow a little adjustment up and down.
