Major advantages of upgrading to this part/product: (1) Upgrade to alloy 7075 material (2) Due to the limitation of installing only one servo on the original servo bracket, the Jet Nozzle can only run left and right. GPM has redesigned the servo mount and expanded the position for installing a second servo on the basis of the original one. Customers can install a second server to achieve the up, down, left, and right operation of the Jet Nozzle
