Most people like to think big: Go big or go home. But how about going small? I 've designed a small VTOL. Hoverbike, Skycycle, whatever you call it, it's small (barely one ton), fast (It can cruise at up to 62 m/s, although ~55 m/s is advised), and with excellent endurance. And it seats two kerbals!
Running on batteries is how I got it so small. twin rotors and SAS wheels keep it stable. Truth is, it's got more power than you'll actually need.
