I got a couple of wings sheeted. The first is the root end just out of the bag. I took a break from sheeting the second set of wings and rough sanded the first set. After the sanding, I put them both on the scale..................16.5 oz each. At that point, I couldn't help myself. I put both panels on the fuse and weighed it. At this point everything is there except for radio gear, hinges and prop. The weight at this point is just over 11 lbs.
