Hope you also have some 30 min epoxy. I wouldn't glue the wing together with that 6 minute stuff. Also, so that you know next time, you can get epoxy, stir sticks (popsicle sticks), mixing cups, brushes and other misc. stuff like that cheaper around town. The brushes you can find at hobby lobby for about half of that price, and the other stuff can be bought at Wal-mart or other such retailer, much cheaper!
Exactly what are you going to put that power panel into? I see you didn't order a box. Also, if you're going to all of the expense of a battery, and power panel, you might as well spend a few more bucks and get an electric starter. It will be a tremendous help!
