KYOSHO Optima 2016 Rear Radio Post Replacement JR-OT07B by JAZRIDER  [JR-OT07B]

Rear Radio Post Designed for Optima 2016

This aluminium rear radio post is an aftermarket replacement built for the KYOSHO Optima 2016 chassis and supplied by JAZRIDER under model JR-OT07B. It provides a sturdy mounting point for the receiver and radio components to maintain stable electronics during use.

Fitment usually reuses the original radio tray or rear bulkhead attachment points; the alloy post swaps in for the factory plastic piece to give a firmer fixing. When fitting, check that antenna and power leads are routed clear of moving parts and that the receiver tray alignment is correct before tightening fasteners.

The component is primarily about reliability and organisation rather than outright performance; securing radio gear prevents intermittent connections and can slightly help with consistent weight placement for tuning purposes.
