Hi- that's the 'real' covering... Koverall. The covering on the outer panels is on the bias to help maintain flexibility. It'll get nitrate dope then a coat of tinted butyrate. I've never done video although my camera has that capability. I don't know if I am intelligent enough to post vids but will try eventually when the Vamyr is completed. You can see the crank in the wing between ribs. I think(?) the full scale had the crank engage a slot on 'aileron' spars but mine has a brass 'slider' that moves on the spars as the crank pivots. It looks the same thru the covering and functions similarly. It's all I could do with hand tools. Clearances need to be tight.
