A brass rear hub carrier that can be used in common with all YD-2 series. Compared to the standard rear hub carrier (7.2g), the brass carrier weighs 49g in total on the left and right, and has the effect of increasing the grip due to the contact pressure of the tire. Since the unsprung weight that directly applies to the tire increases, it is possible to effectively increase traction compared to the chassis weight.
Although there are some disadvantages such as deterioration of exercise performance due to weight increase, it is an impression that the advantage of traction improvement is greater for drift radio control. Especially on P tiles, concrete roads, and low-grip asphalt, you will feel the effect.
