I dug out the instructions from the Trajector box. It uses ONLY CA and epoxy, no regular (white/yellow) glue at all. It says to use CA to glue the fin halves together, and epoxy for everything else. It doesn't say what kind of CA though, so thanks for the pointer to use medium. I'll have to run back to Hobby Lobby with that 40% off coupon again.

The one question I have though is, the fins are plastic. Why are we using CA to glue plastic parts together instead of the traditional plastic cement glue I've always used on plastic parts in the regular Estes rockets? That stuff actually melts the plastic a bit and makes the plastic from the different parts stick together, almost like a plastic "weld".

Thanks again!
