The JR-OT07A front radio post is a replacement aluminium mount intended for RC-scale use on the Kyosho Optima 2016 chassis. Constructed from aluminium, the post provides a firmer mounting platform for the receiver compared with the factory plastic part.
Compatibility: this part is specified for the Kyosho Optima 2016 only. Do not presume fitment on other Kyosho models or unrelated platforms without verifying the listing or performing a fit check. No further compatibility claims are made here.
Fitting notes: install the post onto the vehicle's radio tray or existing mounting points. Standard procedure involves removing the body and original post, aligning the aluminium post with the tray holes, and fastening with the original or equivalent hardware. Exact fastener specifications are not included; consult the seller or your workshop records.
Tuning impact: switching to an aluminium radio post changes the stiffness at the receiver mount. That reduced movement can stabilise electronics during setup and making iterative tuning changes, helping to maintain consistent diagnostics while adjusting suspension or electronics positions.
