lol. I didn't even notice that it was a canadian site. If I do go with an external tank, what size is recommended? Would I also be using smaller fuel line?

I have a few questions about the kit as well. It has a strip of paper with airfoil templates (root and tip). How do I use those? I don't normally do much building and sanding and all that good stuff, I have a few ARFs that I've assembled, but that's about it, and these instructions seem to be aimed at a somewhat proficient builder. In other words, a lot of the information seems to be implied. Instead of me just guessing and messing it up, I figured I'd ask some of the more basic questions that I don't know, so that I don't mess this up.

Also, I thought the wing was pretty symmetrical, but now that I look at it, I may have glued it in backwards. Not sure if I did, it's not super obvious (to me, anyway), but if I did, would it be possible to just sand it the way I want it, or am I pretty much screwed? (I get a little too ambitious with my gluing sometimes)
