England 1987 was the scene of the 2nd IFMAR (International Federation of Model Race Cars) electric off-road world championships. In addition to the standard Optima, Team Kyosho entered a midship motor mounted prototype in the 4WD Class. Racing under its ‘Mid Optima’ project name, the prototype stunned the world making up five of the ten cars to qualify through to the A-Main Final, but unfortunately missing out of the top prize in finishing a credible 2nd to demonstrate its outstanding performance potential. The prototype was close to the final product released to the market under its official name ‘Optima Mid’ allowing racers around the world to experience its revolutionary capabilities. Still as popular as the original back in 1980, the Optima Mid joined esteemed company as part of the Kyosho Vintage Series with its revival in 2022. To commemorate Kyosho’s 60th anniversary in 2023, the original World Championship prototype spec Optima Mid will be released as a limited edition. While sharing the same basic configuration as the standard Optima Mid, the World Championship prototype featured several optional parts as standard and a special body, which has been recreated with a new mold and combined with a large polycarbonate rear wing. A dedicated decal is also included to reproduce the original color scheme. Aluminum parts have been changed from the original gold color to a chic gun metallic in combination with special color wheels to create a style unique to the limited edition 60th anniversary model. The World Championship prototype Optima Mid that never made it to market in its original form in 1987 is enhanced with modern racing technology so you can enjoy Kyosho’s anniversary year with dynamic performance using the latest RC systems and power sources.
