The X10 differs from the DS225 in that it has new electronics with even better resetting accuracy. The motor of the KST X10 servo can be loaded with up to 10gk / cm. The upper part of the KST X10 is equipped with an AI7075 aluminum alloy, which significantly improves the durability and freedom from play in continuous operation compared to the KST-DS225 MG. As with the KST X10 Mini, the KST X10 also uses a harder aluminum alloy on the upper part of the housing, which further improves the freedom from backlash in the long term.
