Hi guys, I'm laying up and bagging a 3 meter wing, with blue foam cores, uni-carbon, and a top layer of fiberglass on a bias. What is a typical weight of fiberglass to use for the bias layer? I was thinking either a single layer of 2.5 oz cloth, or maybe the 2.5 with another layer of 1.4 oz cloth? This will be a thermal duration type sailplane. Thanks!
