flingy.dat contains the movement settings for things like Units, Weapons and IScripts, as well as a refernece to a Sprite. These movement settings may not all be used if the "Move Control" setting is not set to "Flingy.dat control" (for example "Iscript.bin control" means the IScript Entry of the Image referenced by the flingy's Sprite will control the movement).
