Can't post any pics right now, but I hang my electrics vertically between 4 pieces of 1" PVC hung from the ceiling and spaced about 6" apart. I store my nitro planes horizontally in a home made rack that is secured to the wall. Wings in one rack, fuselages in another. Even with an empty tank, if you store a nitro plane vertically, you are going to drip some fuel/oil on the floor.
