The spot on the side mudguards, right near the ESC tray, was designed for mounting switches. I have been using red 3M double sided tape, just like I do for everything else, and never had it come off. I've done this on both of my EB48's as well as my SCT410. I'll try to get a shot off my SCT410 electronics layout up soon for everybody to see. I love it, but folks who had to mod the battery tray probably won't like it, as even more weight is further forward.
