Kyosho has released a Front Mass Damper for their V-ONE R4 1:10 Nitro Touring Car chassis which is a device other than the suspension that absorbs vibrations and shocks. A donut-shaped weight is placed between the upper and lower springs around a shaft fixed to the upper and lower bumpers. Tested by Kyosho’s head of RC car development Kazuhiro Miyazaki, who himself admitted he was sure it would work, when fitted it is possible to absorb minute vibrations that cannot be controlled by the suspension. In addition to the sense of stability when accelerating and decelerating, the sense of stability when the car hits bumps in the road surface, curbs, etc. has also been significantly improved. The set includes two 0.2mm thick shims, and by using them to add tension to the spring, the feeling will change slightly.
