Here's Leviathan, inspired on the Final Fantasy summon, this dragon can levitate vertically or fly horizontally at high speed, changing his posture in the process which is what I like the most about it. Fast and stable, can be used in water, or more like should not be used on land, and takes off vertically and horizontally. With VTOL controls, changing postures also helps turn over if you end up upside down on water. Fold the landing gear before using vertical mode. He can easily dive and resurface in horizontal mode, but don't try it too fast in vertical mode.
This is also my first try at xml editing, since the thing refused to take off with 3 engines I went and gave them more power.
Enjoy
