By using a slide damper hard spring to apply tension to the electrodes, you can break in the motor with stable contact pressure. Since you can push and set it, there is less risk of damaging the motor label with the electrodes. Connecting the positive electrode to the F-stamped side will result in a front-motor car, and connecting it to the R.C-stamped side will result in a rear-motor car and a counter-clockwise rotation for double-shaft cars. The electrodes are easy to attach and detach, providing excellent maintainability. If the electrodes become dull, please polish them with a product like Piccal. The main body is made of carbon resin reinforced PETG. *If you purchase multiple items, we will sell them for an additional 800 yen per piece. For example, if you purchase 3 pieces, it will be 1380 yen + 800 yen + 800 yen = 2980 yen. Since changes cannot be made after purchase, please be sure to contact us in the comments section or via your X account. We will create a dedicated listing for you. *Slide damper springs are not included. Hard springs and super hard springs are recommended. *Due to being a 3D printed product, there may be small scratches or layer lines that occurred during finishing.
