I saw forget the 3/32 skins and use the 1/16. I know you are thinking strength and you don't want the wings folding when doing a high speed maneuver With the 1/16 sheeting that is not going to happen. If you want a nice flying bird use the 1/16 balsa sheeting and cover with the covering of your choice it will be fine. Just make sure you glass the middle if it is a 2 piece wing join together. Which kit it is you are doing?
