Kyosho KYO 30623 - Turbo Optima Mid Special 4WD Racing Buggy Kit

At the 1987 Electric Off-Road Car World Championship in the UK, the prototype Optima Mid dominated the 4WD A-Main final race securing 5 out of 10 starting positions. Following its success, the Optima Mid was commercialized to achieve worldwide racing acclaim. In 1988, the Turbo Optima Mid Special was released in limited quantities as the final evolution of the Optima Mid and sold out instantly due to overwhelming demand. Now, this legendary machine returns in 2025 as Volume 18 of Kyosho's Vintage Series. The original Turbo Optima Mid Special featured an 18mm longer wheelbase than the Optima Mid, enhancing high-speed stability and cornering performance. Its main chassis was designed for improved battery weight distribution and constructed from FRP sandwiched between carbon plates, striking an optimal balance of flexibility and rigidity. The belt and belt cover were also specifically designed for the Turbo Optima Mid Special, and the body was newly created to match the chassis. This faithful reproduction retains all these defining features while incorporating updates to support modern power systems and R/C electronics. Previously optional parts are now included as standard, along with several newly developed components. Unlike the original, this is not a limited edition but a permanent addition to Kyosho’s catalog. The return of the Turbo Optima Mid Special to modern circuits is a dream come true for all fans, whether they were lucky enough to own the original, or missed out due to its limited production. Now anyone can drive the ultimate evolution of the Optima!
