Yeah I am currently in the second year of my 3 year mechanical engineering course, which, if all goes well, shall be followed by a B.E. in aeronautics.
I have researched electrical systems and although they are simple , it will cost you very much. Its all about hard to get specialized electric motors and battery packs. And even then it would be difficult to make it half as good as tesla.
And the conventional system, although complex, with some tunes and a turbo, you got a beast on the road.
