The JR-OT07A front radio post is an aluminium replacement intended for RC-scale use on the Kyosho Optima 2016 chassis. Constructed from aluminium, the post provides a stable mounting point for the receiver and associated wiring, replacing the stock plastic post.
Compatibility is limited to the Kyosho Optima 2016 as named. Do not assume fitment on other Kyosho models or different chassis without verifying with the seller or performing a test fit. No additional compatibility is implied.
Fitment notes: the post uses the existing radio tray or mounting points. Standard practice is to remove the body and the original post, position the aluminium post over the tray holes, and fasten using appropriate hardware. Exact screw sizes and torque figures are not included; consult the vendor or your workshop guide for those details.
Usage advice: the aluminium post reduces movement at the radio mount and can aid stability during setup and maintenance. This helps keep electronics placement consistent when adjusting suspension or during repeated service cycles.
