Hi Andi,
hier die Antwort auf meine Anfrage ...
I see what you mean and would assume that it is possible. You would be required to have a customised USB cable that connects to the AV out port on Stella, and power the entire aircraft with a flight battery. The only issue is having your entire platform under power for the period it takes to copy the files, as everything will get hotter the longer it sits there. The only task required to remove a GoPro from Stella is to undo the thumb screw at the right of the lens, which allows you to slide your GoPro from the gimbal.
Stella is a complete stand alone gimbal. It happily works as a stabilised hand held gimbal with just the addition of a power source. The four ports are not connected in any way to the FC or other flight modules, except for the radio receiver to manually control tilt and the switch function for automatic 90 degree tilt. If you are using Stella for a different FC and required FPV or a ground link to your GoPro, you will need to make a cable from the Futaba style 3 pin plug to the OSD or AV TX as the cable Stella comes with is specifically for the XAircraft OSD.
Warm regards,
Anthony
