It's looking really nice Kev. I usually get some kind of waves here and there whenever I build with 2mm. I don't know if it's so thin that it gasses off when you put various glues on it, whether it's the heat in the field, or what. Kind of an annoyance, but to use that over-used cliche, it is what it is, I guess.
Looking forward to seeing this thing put together and some flight video!
