download RTB, then get slate desert 2 or a map other than construct...
way easier to build on... mentally.
ever try flying a plane doing an airshow in a blank construct, destruct, or slate? you can't tell your altitude, and you get all paranoid about hammering into the ground at a hundred miles an hour. which really isn't much of a prob, unless you go through or have a vehicle falling damage script of some sort.
