I am using the 3m tape but also take the extra time to drill a couple of holes through the battery tray. I never had an esc come loose with a screw or two holding it to the tray. It pays to take some extra time and route the wires so that they won't get pinched. I add heat shrink anywhere it might rub through the insulation. The Orion switch fits neatly in the little area offset from the main battery area.
