yep, actually the original maker of this plane used EPP foam for the construction, like the AAs. here's a picture of his. as you can tell, he's got a LOT more dihedral in the canard wing. this is something i strongly suggest doing, without it you'll have really hard turns. he also mounted the motors on top of the wing, this is a good idea as well. with my motors underneath, the props were vulnerable to hand landings. for my balsa version, i used wing ribs to get the undercamber in the wings, but on his foam version, he actually carved an airfoil. if you dont want to do that, a heat gun would probably work. if you roll the foam over the edge of a counter or table, it should curve nice and evenly.
