Mounting Pan - Tilt Camera to the Cover Plate
The pan-tilt rig will mount to the forward-most servo footprint on the cover plate.
The horn goes under the cover plate. Use two of the self-tapping screws included with the horn to mount the horn to the plate from the top (see pictures below) using the holes that line up.
It’s important that the rig is mounted so that the middle of the servo travel faces forward. This will take some trial and error, but you want the servo to be able to move an equal amount in either direction when facing directly forward (it’s okay to move the servo when it isn’t powered, just don’t force it).
When mounted, it should look similar to this.
