Woah, glued blades? Maybe I underestimated the power of glue

At first I figured my glue job would be fine since there's not a lot of pressure on that little joint, but I got a little skittish after posting and thinking for a while. Before I glued it, the air flow direction was reversed, pushing the heli into the ground rather than up. I can't imagine how bad it would be if the glue gave way in mid-flight and SLAMMED the heli into the ground. But I'm still working on hovering at about 1 foot, so I figured I could go a while without replacing it
