-The Fat Shark 5.8 GHz module for Dominator/Attitude etc. goggle is probably the largest there is that will fit. Because of the shape of the Base SD goggles, the pins will need to all be slightly cut. The two lowest pins, "+5V" and "GND" are the ones that actually define the fit. The smudges around the middle solderings on the back side of the module were there already when I got it.+The Fat Shark 5.8 GHz module for Dominator/Attitude etc. goggles is probably the largest there is that will fit.

 Dip switches come in at least two varieties. The one used here is the smaller version of the IC kind. All types serve the same purpose but fitting something small is obviously easier when available space is limited. Dip switches come in at least two varieties.

There are some fragile connectors inside so don't push anything inside with force.
  
 Once the parts have been separated, the bottome parts needs some modifications to fit the module and the dip switch. Start with a 7 mm drill bit and slowly drill from the bottom side where the screw hole is. This will remove the plastic pole that would otherwise block the receiver module. Note that this step may not be necessary if some other smaller module is used. Then figure out a place for the dip switch. The bottom was used in this build with holes drilled for the connector leaving the switch itself outside and usually also out of view. Once the parts have been separated, the bottome parts needs some modifications to fit the module and the dip switch.

-The top part needs to be carved a little bit to with the antenna connector of the module. The plastic is somewhat soft and using a sharp knife instead of a drill felt the best way of doing it. Test fit with the module until it looks nice.+The top part needs to be carved a little bit too to fit the antenna connector of the module.
