I made a stock recreation of the Diamondback Explorer, made by Lakon ships in Elite. It does fly, though its like you strapped a paper airplane and fireworks to a brick (Barely picks up)

Fully stock, kerbalx's craft preview proves that. You don't need infinite fuel to fly. For cosmetic reasons, it is not able to go into space (needs air), but you could replace the engines, and then it would.
This ship also works as a submarine! Also turn off steering on the wheels
After I made this, I looked at Mordecai_Ender, sees that it is so much more simplistic, and realized how giant mine is. Good work though, CMDR. o7
