Kyosho Ultima 87 WC Worlds Spec Kit - 20th Anniversary Ltd Edition

Celebrate Kyosho’s World Championship heritage with the Ultima 87 WC Worlds Spec Kit (K.30645B), a limited-edition release marking the 20th anniversary of Kyosho America. Based on the works team car engineered and driven by Akira Kogawa at the 1987 UK EP Off-Road Worlds, this kit blends period-correct styling with updated R/C engineering for today’s systems and power sources.

Gunmetal anodised aluminium and carbon fibre components, combined with a range of previously optional upgrades, deliver precise, responsive handling beneath the sharp low-profile Optima Pro-style body. The core 1987 design is faithfully reproduced, while refinements ensure smooth integration with modern electronics.
