Hi 67,

Sounds like a poor design to me. 3/4 of an inch isn't much tape, 2" packingtape would be better. But I cant even believe the mfg signed off on taping the wings together. It's only going to be a few flights before oil starts working it's way under the tape and starts causing problems. The wing should be glued and the seam glassed. What really gets me though is how was your buddy to know it was a poor design? The MFG is at fault here and completly failed your friend.
