These are premium vibration damping balls that you can use with your gimbal / flight controller mount to remove any unwanted vibrations. See the extra images to see some applications. The extra quality of these damper balls can be seen and felt in the extra softness in the top of the balls (where the vibrations are absorbed), and the extra rigidity in the premium plastic used.

Note: These balls are sold in packs of 4.
