I already gave you the answer, why is there another thread. Automation is for car building only as it's for Automobiles(cars).
Hmm. If you made an automation plane body mod, two wheels in front, one in rear... cool conept but I'd imagein right off the bat it'd take tweaking to get it to fly and you'd likely need something to control the airfoils, having some flight at 300kmh is easy but controlled flight is the question
I know I am bumping but I am gonna say that it is possible, its been done, you can find 2 examples of aircraft in the repository. They are small however and I'm not sure if it would be easy.
