Switching the leading edge to lighter balsa
I recut all the leading edge balsa blanks, after asking my self "Self, why are you using the denser balsa instead of the lighter less dense balsa?"
Four leading edge lighter balsa blanks - 47.8 grams
Four leading edge denser balsa blanks - 80.9 grams.
The weight savings will be less than that after shaping the wings, but still a large weight savings. I'll leave the thin trailing edge blanks as the heavier balsa.
Total wing wood weight except ribs - 75.8 grams.
