This is Pan and Tilt module developed for the Walksnail VTX V2. It is inspired by the excellent work of Bonafidepirate on the Runcam Split 2 Low Profile Pan Tilt.
The module has been designed to fit the TGY-R5180MG 180 degree servo sold by Hobbyking as it's pan servo and any generic 9 gram servo with a ball link for the tilt. The VTX mounts to the module with the mounting screws included with the VTX.
Simply use the longest screws. Remove the screws that hold down the antenna/camera cable covers and replace with the longest screws. Press fit the m2 nuts into the holes on the bottom of the mount and screw the VTX into those nuts from the top. (See photos for more detail)
