Thank you for viewing. This is a radio-controlled excavator. The controller is not included. There is a broken part on the arm (see photo 8). It has not been used outdoors, so it is relatively clean. Although I have not confirmed the operation because there is no controller, it worked without any problems before. The arm also works. The size is approximately 12cm in length, 10cm in height, and 8cm in width for the main body, and approximately 23cm for the arm. Thank you.
