RS3147 shots, foot to the floor, three cakes fused into one straight firing block. The RS3 from Brothers Pyrotechnics is named after the hot hatch and behaves like one. No clever cornering, no fancy choreography, just straight line aggression. All 30mm tubes, the biggest bore you can buy. Every shot lifts a full break: golden brocade crowns followed by deep colour changes that thud in your chest. 3kg of powder, lasting over two minutes, a beast of a cake
