this is apan and tilt camera mount that uses a standard servo for pan and a micro servo for tilt. attach the standard servo to the base, then the servo horn to the bottom side of the mount it has a place to fit just screw it on then tighten the servo horn to your servo, attach the micro servo then use a push rod from the micro servo to the camera for tilt. the servo horn for the camera can be found on my designs page. attach camera and wire it up . this requires 2 channels for pan and tilt, but you can just use pan of you do not desire both functions or do not have 2 channels to use.
