If you race or practise on varied surfaces, the JAZRIDER JR-OT12 JAZRIDER JR-OT12 carbon radio plate is a direct upgrade for the Kyosho Optima 4WD. The carbon construction reduces flex in the radio area while keeping the whole assembly light and responsive.
Using carbon fibre lets you gain stiffness where it matters without penalising mass. That translates to more predictable handling during corner entry and better feedback through the steering linkages.
The plate is CNC cut to align with the Optima 4WD mounting points, so fitting it is straightforward with common RC tools. It keeps stock component layout and lets you get back to tuning quickly.
