It is certainly not a scam, very genuine one man development with lots of outside help from very interested persons as you can imagine and very welcome for more.

The current prototype is the first iteration and as with most things that require development it won't be the last one. The control systems and "ground effect" issues as well as forward motion are all being worked on, it is time consuming and a slightly expensive project so far, so outside funding assistance is welcome at the website, as is technical assistance.

The basics have mostly been addressed previously by the likes of Hiller Aircraft and a lot of others so issues are known and this project is about using that groundwork and pushing it forward.

If it fails it will fail for genuine operational reasons and not from being a scam, detractors are part of the progress problem, it is a catch22, ask for assistance either knowledge, research or financial and cop the bad with the good.
