There are also two videos regading the system, but keep in mind the version in these videos is rather old





 

Sweet just one question though, does the wifi signal have much effect on 2.4Ghz / 5.8Ghz signal around? e.g. interference

Hey there,

the WiFi signal has no affect on the FPV transmission. We're using the system a lot on the field and at present in a tennis hall without any problems. Other people who are using the system also say, that they don't have any problems
