I got my Alpha second hand and there was no tape, I went to my LHS and got some other tape, very strong stuff if I remove it the tape will take the covering with it. Well the guy at the LHS told me to glue the wing together, my first flight I did not, but I did not long after, I have not had any problems, and my tape is still there. However last time I flew it I felt some movement in the wing halves which I am going to keep an eye on.
