- | Since I was already a little bit annoyed of carrying an additional tripod + the ground station case around, I decided to order the Fat Shark receiver module designed for Dominator goggles for around 30€ with a "how hard can it be" attitude. The assumption was that since that same module fits the similar Attitude goggles, it shouldn' | + | Since I was already a little bit annoyed of carrying an additional tripod + the ground station case around |

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.

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.

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.
