This is an RC-scale accessory consisting of two brass collars intended for the hole position on DF2028 and DF2030 assemblies. The part is made from brass and supplied as a 2pcs set, designed to sit at the specified hole location on the DF-02 platform to provide a durable contact surface and consistent alignment when fitting associated components.
Use this collar where the DF2028/DF2030 hole position requires a metal insert for repeatable positioning during assembly or maintenance. The piece is neutral in function and intended only for RC-scale DF-02 preparations and tuning tasks, offering a simple mechanical role rather than any electronic or performance upgrade.
Installation note: the collar is sized for the DF2028/DF2030 hole position and should be placed into that location as part of the chassis assembly; verify fitment with the DF-02 components before final tightening.
