I have now made a test piece of wing out of unused wing ribs and some scrap wood. The wing section was fully planked and then covered with 0.15mm litho plate, contactglued to the balsa. I weighed the section before and after fitting the litho. This is the moment when things turned sour... To give some comparison, a Quickie 500 40-size model would gain about 500g in weight when covered in aluminium. OK, part of this would be Monokote anyway but the weight gain is not acceptable. But, the look of it is absolutely stunning! I will use it to cover small areas in the future I think.
