As you can see in the pics is the results of gorilla glue. I guess if I were to do it again I would use a lite coat of epoxy to sheet the wings . look in pic 3 and you will see what I mean keep and eagel eye on it until it sets up . the foaming action of gorilla glue will move the parts around as it foams. I had 30 lbs od lead weight and it still moved and I missed it. NowI have to scab a piece of balsa to cove this area. One thing though if you let the sheeting hang out 1/2 inch you can omit the 1/4 " trailing edge piece. As in pic 4 & 6.
Pic 5 showes the leading edge fully sanded and installed with titebond glue. I am having to think hard about how to drill stright holes in the fusealage to accept the aluminum spar and fit the wings to the fusealage.
