Kyosho Ultima RB7.5 2WD 1:10 Competition Racing Buggy EP Kit

Rennbaukasten ohne Fernsteuerung und ohne Antriebskomponenten

Kyosho’s 1/10 scale Ultima EP buggy boasts a rich racing history, including multiple world championship titles, and continues to offer a diverse lineup ranging from entry-level to high-end models. Now, its top-tier RB7 has evolved into the upgraded RB7.5, incorporating numerous refinements to enhance performance.
The new model adopts big-bore oil shocks equipped with X-ring seals for smoother operation and leak prevention. The shock stays have been upgraded to lightweight yet highly durable carbon fiber, offering greater strength for intense racing conditions. A newly added front shock stay guard helps prevent damage during rollovers. At the rear, aluminum bulkheads and hub carriers enhance rigidity while broadening setup options. The body is based on the RB7, but a spoiler on the rear of the cabin combines with an improved rear wing and the addition of a front wing to optimize aerodynamic performance.
By integrating newly developed components and standardizing several high-performance upgrades, the RB7.5 remains true to its original strengths while evolving into a machine capable of competing at the highest level. Whether on traditional dirt tracks or modern high-grip carpet surfaces, this latest Ultima model is built to meet the demands of competitive drivers.
