Mini 4WD Mass Damper Placement Guide

A mass damper controls rebound after a jump or slope by moving independently of the main chassis. Placement matters as much as mass: a weight further from its pivot can produce a stronger damping effect.

Move before adding weight

Start with a light, freely moving damper and observe the landing. Move it forward, rearward or outward before adding mass. Front damping can address nose lift; rear damping can calm the exit from longer jumps.

Keep movement smooth

Binding hardware defeats the purpose. Use suitable pivots, check clearances and inspect the assembly after crashes. A heavier system is not automatically safer if it makes a tight course sluggish.
