4dogs,
"No matter how far you have gone down the wrong road, turn back." (old proverb)
I do not advocate "quiting" as you suggest. I advocate spending those resources on other more elegant concepts for VTOL. I have some ideas of my own (hire me.) and I am aware of many other concepts for VTOL.
This project is an example of using engineering to (in your own words) "make it work." If anything is that difficult to "make it work," then that is an indicator that it is a bad idea.
Don't give up. Just start over.
