Silvia's mechanics are all Sanwa. ESC is SV-D2 Gyro is SGS-02 Servo is PGS-CL2 Motor is 13.5T Type R MT-5 batteries have been replaced with the optional ones. Therefore, you can play longer than with dry cell batteries. Supra's mechanics are normal. Custom points are upgrade parts 1.2 Parts 3 are not installed. Wheel nut socket and turnbuckle socket for electric drill are also included. A pre-cut R34 GTR body is also included. Used mainly for asphalt driving. I started this as a hobby, but I don't have the opportunity to do it, so I will give it to someone else. I am a beginner, so I may not know much about settings. I bought everything new, but since it has been in someone else's hands once, please understand that there will be no claims or returns.
