FASTRAX NITRO STARTER SET w/2x Wrench s/drivers - starter - chgr - bottle

Reimagined from its world-beating origins, the Kyosho Optima Mid Legendary Series – Koswork Edition (part K.30622KE) blends vintage style with modern race-ready engineering. This special edition adds premium Koswork carbon and hardware upgrades to the Optima Mid platform, boosting rigidity, precision, and durability while preserving the iconic mid-motor, belt‑drive 4WD layout.

Updated for contemporary electronics and motors, the Optima Mid features an efficient 48‑pitch drivetrain, adjustable belt tensioner, reinforced slipper clutch, and a countersunk aluminium main chassis. FRP shock stays and gold anodised threaded oil shocks deliver composed handling, while the faithfully recreated bodywork captures the classic racing aesthetic.

Celebrated for its stunning debut at the 1987 World Championships, the Optima Mid helped define the layout and performance benchmark for modern racing buggies. This re‑creation captures that spirit with thoughtful updates for today’s tracks and power systems. The 48‑pitch pinion and 82T spur gear share a similar spec to platforms such as the Ultima RB7, with optional 78T/80T spur setups also suggested where appropriate.
