got mine covered and assembled tonight. all I got to do now is install motor, radio and landing gear, airframe with covering came out at just a little over 6 ounces. btw, I used tape hinges made from 3M scotchpad 3750-p packaging tape, it comes pre-cut in pads 2 inch by 6 inch and is fairly fuel proof. I've usually lost covering before I lost the hinges and they work for little bitty planes up to big gliders and small power planes, about the best for electric. you can use it to seal a complete hinge gap or use strips if weight is a concern (itty bitty planes). if you burnish it down with an eraser or burnishing tool it pretty much disapears. see if you can spot them in the pics.
