i usually use the "2 fold" technology for faster/futher airplanes, keep in mind i use just plain notebook/printer paper, dunno how big that nvidia poster is, maybe you can fold it more. Like when you bend it in half and then go to make the wings, instead of just folding them once, fold twice, and more as you go on, to make it more aerodynamic. and the back of the wings try bending just a little part of them up to give them degrees of steering.
