Exactly, it's no fun if it can't get off the ground. I try to keep a median between its looks and functionality, in the end you are modeling but modeling also means trying to incorporate the functionality of the real life variant into the game. I made a couple of functional and good looking rockets heavily based on real design back in .16 but I lost my saves when I updated. I'll try to remake some of them and maybe some of us could start a nice thread in the spacecraft exchange.
