Thought this might be interesting for those that want to go fast and still film in HD without putting a GoPro on top, be it for weight or drag-efficiency reasons. It also was going to be my first F7 FC and BF 4.1. And what can I say, awesome mix, all the components ended up being a 5 level stack !! If I had not succeeded in putting the hellgate buzzer as well as the cap onto the XT60-pigtail things would have been problematic, as their really was no more space inside the frame. I also always coat my electronics with a special electronics paint that has a blue-ish tint to it.
