I have to admit I don't understand the fascination people seem to have with glassing the wing. Look at it this way. Fiberglass only has strength in it fibers. This means it will only have strength in the direction of the fibers for as long as the fibers are. So any fibers running chord wise are providing no strength to these "high G manuevers". Also The extra strength stops as soon as the fibers stop. Someone suggested putting a 3 inch wide strip on the centre of the wing. Well that helps the first inch and a half of each wing but what about the rest?? The wing is only as strong as its weakest point. My GP bipe's fuse is more than 3 inches wide so the glass would not extend past the fuse edges. I am willing to be that if I stressed the wing to overload it would break outboard of the fuse so in this case glassing the wing would do nothing other than add weight. I don't know about you guys but I have never seen a wing fail right in the centre. All failures I have seen have been from the edge of the fuse outboard. Adding glass to the edge of the fuse would actually be worse because of the load transfer from the glass is focused when the glass stops.
If you feel better glassing your wing go ahead but I would rather save the weight.
P.S I have a GP RV-4 a GP ultimate bipe a seagull Edge 540 and a UCD 3D. None of which are glassed and I abuse all of them.
