The SPT100 System is perfect for cameras or sensors up to 10 oz. This unit can be mounted upright or mounted upside down. If you are needing more than 90° of movement for the pan, you can order servos from us pre-modified for this on the Hitec servo pages. We recommend either the HS-485HB for applications up to 6 oz or the HS-645MG for applications up to 10 oz. Any standard size servos will work. Unit comes unassembled with instructions. (Servos and camera not included and must be purchased separately).
