Seems like a good solution Jim, i go for that one ...

By the way, i am gonna use two of your regulator ( jaccio without switch) 5,7 and 5,1 for primary and secondary battery. (800+400). I also thought i should plug the receiver power directly without any switch, since i have to remove the canopy anyway each time. Just wondering if there will be any wear on theses connectors over time ... I could also put a small extension cable between the batteries and the regulator and "sacrifice" those plugs instead of the regulator-plugs ... What do you think ?
