The glue joint doesn't know how fast it's going or how powerful the motor is. It DOES know how much stress it's experiencing and, if necessary, how strong the materials being glued are. So a blanket recommendation based on power makes no sense. One can design to minimize stress. If you are butt gluing large 1/16" carbon fiber fins, without fillets, on a fiberglass tube, you are going to need fancy epoxy. And they'll come off, maybe. Not so if they are short, wide 5/16" balsa with good fillets.
Then there's flutter, but the consequences of thickness are similar.
