Coming from AVID are the carbon servo mount spacers. The servo mount spacers come in two thicknesses (1.5mm and 2.5mm) and provide your servo with a rigid mounting surface to ensure that your servo stays tight and the screws don’t loosen as the plastic shims compress over time. You can also think outside the box and use them to shift weight around by moving a servo forward or even up in 8th scale. Comes as pair in a doodad container.
