When I started my scratch build project I had planned to vacuum bag all the molded parts. A friend who had a lot of molding experience said if I was diligent about removing excess resin I could do almost as good as vacuum bagging. I think I was successful. The fuselage is 83in long. I used one 2oz and one 10oz layer the full length and an additional 3oz layer from wing trailing edge to the nose. The left fuse half weighs 1lb 3.6oz and right half is 1lb 3.8oz. The left half is shown above. The finished airplane is 21.5lbs dry. I had estimated it would be 22lbs. I feel that vacuum bagging isn't worth the extra work for most home projects.
