This is not how true science works. First, you hypothesize a theory, then your theory takes shape (pardon the pun), then you test it out, then you explain it in practical terms.
Some guy in a barn just invented the combustible engine for a car, and you're asking for the design schematics of a 1950 Ford, Model T. "Oh, you may have invented an engine, but if you can't show me a car design, it'll never work." 
.
The issue here is that people have been successfully using the globe earth model to navigate to the most remote corners of the world for five centuries now. This is not some sort of recent discovery.
In your analogy, it's a reasonable question to ask, Does the combustible engine you designed work when you turn it on? If it does not, then you have not designed an engine. That's where we are here. And the OP asked in the initial post whether there was an engine for the flat earth model, and apparently there isn't one, since no one produced it. So we're not even at the state you described.
Your expectations are completely stupid and show your lack of critical thinking.
This is a very uncivil way to talk. Can you please try to show at least basic courtesy when you speak to others on the internet.
