A friend gave me a kit that had been started about 15 years ago. It is a trainer. This looks like a plane to try a couple of new techniques on. To make a better looking center section joining the wing panels with three layers of thin fiber glass, each cut wider than the one below it, may avoid the ridge that occurs using the typical 3" tape. Would laminating epoxy work in this application or should a slow say 45 or 60 min structural epoxy be used?
