If you buy another Apprentice or have to replace the wings or advise a fellow modeler the original instructions on putting the wing together just used the leading and trailing edge plastic with the built in tape.

Ihave over 50 flights with just tape on the wing center line. I only got going on this as you waited overnight for the epoxy to set. There is a great advantage to taking the wing appart easily for long range transport or shipping if you sell it used. fiberglass reinforced tape is good but overkill.

Most glider wings are held together with less and they don't have problems.
