Description
A mass damper set built around a slimmer 7mm diameter body than Tamiya's standard mass dampers, making it easier to fit into cramped areas of a chassis. The set covers two different lengths and weights, giving builders a wider choice of damping mass than the standard parts alone.
- Diameter: 7mm
- Includes 2x damper, 5.5mm length, approx. 1.5g each
- Includes 2x damper, 11.5mm length, approx. 3g each
- Compatible with: all Mini 4WD and Mini 4WD PRO cars (some chassis or bodies may require modification)
A mass damper works by hanging a small weight from a screw so it can move independently of the chassis: on landing, its inertia keeps pulling down for a moment after the chassis has already stopped falling, soaking up energy that would otherwise bounce the car back up. The 7mm body is slimmer than Tamiya's full-diameter mass dampers, so it tucks into gaps a wider damper won't clear, and the two included lengths let builders mix lighter and heavier damping across different corners of the same chassis.
