Flyn, what were the wing spars made of-- balsa, spruce or some other material. Hanger 9 had a problem with the Edge 540 a few years back with its wing. Seems the wing spars were only balsa stock and broke apart in the air. Hanger 9 replaced many planes because of that mistake in production. I hope our PW300s have more than a balsa spar in the wing.
