Have been trying to come up with a way to store and a way to transport various engine model engines built from say like 1/4 or 1/3 scale hit&miss casting kits. shelves in the living room had mixed response. the various bases don't help like skids or wheeled dollys or just a base board on some. the combination of weight and tippy-ness,plus the smelly gas in the tank and splashed lube are a problem too.
