A helicopter can't moor to a wall or land on slope surface. Maneuvering a helicopter changes angle positions and loses targets. Its screw closes operating space above. Here is given the design of a flying and soaring device (rotopter) free from these problems. It uses side circulating wings whose quasi-horizontal paths of circulation provide necessary thrust for hovering, lifting and flying. Rotopters can be with one or two thrust delivering plants. The first type rotopter is useful as a personal flying device able also move as a car, a sledge, or a boat propelled by the same thrust plant. The second type rotopter can occupy any angle position. It can tilt, state horizontally or vertically, flying and landing this manner. It can moor to a vertical wall or a cliff providing rescue or assault operations. Automatic redistribution of active power between the thrust plants allows it.
