BUILD - FLY - INNOVATE YOUR VERSION OF HS-DRONE
Most new aircraft are incremental changes to concepts known for decades, including the V-22 Osprey (bicopter) tiltrotor and the B-2 flying wing. Also, it takes too long and costs too much to commercialize these incremental changes. Transformer Drone and SP-Drone are breaking out of this paradigm, starting with patents/applications.
