This is a set that is part of an experimental Ninja LEGO theme of mine. There are basicaly three factions: the Emperor's army, the Outlaws and the Natives of a dinosaur-inhabited island.
About this creation
In the Emperor's fight against the desperate Natives, brilliant engineers designed a winged machine that will match the Native's riders of winged lizards. Now the Empire's army needs not to worry about sky raids. Shogun Suzuki has been willing to test the invention.
Here is a shot of the prototype at an angled position. Notice the banners flying high and the three wings providing extra stability to the vehicle.
Here's the back. As you can see, there is a "steering" wing.
