I just purchased my first set of SES parts and am trying to connect a C bracket and multipurpose bracket. I fit them together fine, but I’m having trouble hooking up the servo with the snap rivet fasteners. Is there a detailed description of which part hooks in first? I can get one side of the servo in but not the other. Also the servo seems rather loose. Obviously I am not hooking it up right and am looking for details on the right order of hooking the parts together. Also should I be using any of the other pieces that came with the servo?
