I once built an advanced VTOL aircraft using wiremod. It worked using a series of gyroscopes, an advanced pod controller, a few hydraulics, some stabiliser thrusters, and one big-ass expression chip. The great thing about it was that the propulsion, steering and lift were all provided by two thrusters, so it worked like a real VTOL.
That was a long time ago, though. I gave up about a year ago. Before I quit, though, I was the kind of guy you turn to when you want to learn how to use wiremod or how to code in expression. Ah, good times, good times.
