The document describes a project for a CUV (Ultralight Versatile Tiltrotor), which would be the lightest two-engine aircraft in the world. It would use counter-rotating propellers and a special harness to function as both a plane and helicopter. The CUV would have applications in rescue operations, patrols, equipment transport, and scientific research, providing mobility in remote or difficult to access areas. The authors propose starting a company to produce the CUV, with plans to build 1000 units in the first year, reach the break-even point within a year, and ongoing investments in marketing, R&D, and continuous improvement.
