Looks to be the accumulation and application of Dennis Fetter's design and production work for many years in China. That production was supposedly for China'a power plant industry, for remote control powerline inspection.
Many westerners, myself included, thought the application would eventually, and easily, haunt the western world in the coming future in a military offensive application. Now being offered to anyone, worldwide, who can pay the asking price. I'm sure no sanity or proof of mental stability is required. Nor proof of not being associated with extremist war-like groups.
Here's a thought: Any crashes of this attack/observation helicopter...will DF continue to state the blame entirely on the operator, claiming insufficient or complete lack of training to be the sole cause of the mishap?
I look forward to hearing what Mr. Fetters has to say regarding whether this war machine is any of his design, and who absolutely believes that gyroplane rotors fly without deflecting any of the airstream downward to provide lift.
