This is an RC-scale mixing base supplied as a replacement spare for the Concept 60 helicopter line. It serves as the central mounting and pivot point used where cyclic and collective mixing linkages meet the rotor control system, and is intended for hobbyist repair and maintenance of Concept 60 models.
The part is offered as a direct replacement component; installation typically involves removing the original mixing base, transferring linkages and any associated bearings or hardware, and verifying neutral geometry before flight. Because part dimensions and mounting layouts vary between head designs, confirm visual match with your existing Concept 60 mixing base before installation.
In tuning and setup, this mixing base helps maintain the intended relationship between cyclic and collective inputs. Swapping a worn or damaged base can restore predictable mixing behavior and support consistent servo-to-rotor response during rotorhead adjustments and routine maintenance.
