Another sorta newbie question here. I brought 1 rocket to the last launch that I attended and I kept it in a long, skinny cardboard box for the some hour ride. I'm planning on attending another launch soon and I plan to bring 3 rockets this time. All are low powered and relatively small, ranging in size from 13.5" to 33.5" with the standard 18mm & 24mm engine diameters. Do 3 long skinny boxes work just fine? I keep worrying that the fins will break in the boxes, but perhaps that just represents paranoid newbie thinking?
