The JR-OT04 aluminium steering servo saver set is intended for the Kyosho Optima 2016 chassis and handles the steering linkage interface within the model. It replaces the original saver components with machined aluminium parts designed to occupy the Optima 2016 steering assembly and function as the sacrificial join between the servo and the steering bellcrank.
Installation uses the Optima 2016 saver mounting points and common steering hardware for a straightforward fit. During assembly verify alignment, confirm full-range movement of the saver, and ensure no interference with other linkages before final tightening of screws.
In tuning the saver represents a compromise: add preload or increase linkage stiffness for a more direct steering feel, or reduce preload to prioritise servo impact protection. Make controlled, incremental changes and validate the setup through test runs to achieve the desired behaviour.
