I would make this out of cardboard if I were you. because pep will turn the model to $hit because of the curves, and it'll be ALOT of folding.
Just make it from scratch, you'll have a much easier time, and don't forget the Body filler.
Here's my attempt at it. http://405th.com/forums/index.php?act=Prin...f=27&t=6545 I started it a few months ago but all of a sudden lost all motivation to do it heheh. I've started on it again and it's looking a lot better. I'm adding detail to it now and then will be almost ready to paint the torso, shoulders, and helmet after a lot of adjustments.
