- Yes, but how many has he or his students gotten back intact, especially
- after several flights. Hot glue softens with heat, and unless it's
- rather cold, it isn't particularly rigid either. It's just a poor
- choice. White glue (Elmer's) works fine, yellow carpenter's glue
- is better, superglue or epoxy are better yet. I usually use
- a medium-viscosity superglue to join the fins to the body, and
- use epoxy for the fillets. BTW, I learned this from cdt, who's
- done far more model rocketry than I, and I measure my experience
- in decades. If he says a construction method doesn't work well,
- I believe him! His models don't come apart very often, and
- when they do, it's generally not at the glue joints, rather the
- structural materials (fin stock, body tubes, etc.) give way.
