RE: 1/2 A electric
I had a buddy to cut the cores for me from pink foam board and they curled up pretty bad after they sat for a few days, no luck trying to straighten them yet. I ordered balsa and skins from Lone Star and it's hard as a rock. The project is currently still on the bench, I just have to get new cores and learn to like the heavy wood. As small as the cores are I may try to shape some by hand with pill foam, I have done it before with great results but that wing had no lead outs. So right now it's back to the drawing board.
