Darth Prin No. 5, I try to make the paper plane with polygonal like (say something like Stealth plane). I use internal folding technique similar to DP01, but this time, internally fold the two wing to create shape. Folding line is very critical to this plane design. It might as well fly over 30 m or simply fall on foot depend on the quality of folding. The paper is office A4 paper. Have fun.
