A few days ago, fredoichi posted a photo of his Makoto Zero Sky Fighter, which used 2x2 trapezoid flags as the wings, with a couple of Technic half-pins clipped to the front edge of the flag/wing. I think it's a new technique.
Legoloverman used that technique to build three new spacecraft, Blacktron F-Bomber, Blacktron Space Raider, and Space Police Viper.
But legoloverman didn't just copy. He added a few twists of his own. First, he used lever bases instead of the half-pins. Then he doubled up the trapezoid flags to produce larger front wings for the Space Police Viper. Finally, the tail fins of that ship are made by overlapping two trapezoid flags on the same bar.
