The JAZRIDER JR-OT07A aluminium front radio post for the Kyosho Optima 2016 replaces the factory plastic post with a stronger aluminium mount. This replacement helps cut down on unwanted movement and supports a more stable steering feel on technical tracks.
Aluminium offers a firmer support point for radio and servo assemblies, limiting flex that can soften steering response. That improved rigidity can translate into crisper turn-in and steadier mid-corner behaviour.
Install using the existing mounting points and check screw tightness after a few runs. Correctly seated hardware avoids play and keeps the steering predictable under load.
