This is a replacement Novarossi REX Piston Retaining Clip Ring, and is intended for use with the Novarossi R91HR 3D helicopter engine. These clips are used to retain the wrist pin inside the piston, which secures the piston to the connecting rod. If you ever remove the clips during engine maintenance, the clips can become damaged. It is recommended that you replace them with new clips to prevent possible failure caused by used clips.
