Was at the field and a guy was test flying his new apprentice trainer.. He had lost his last one in a crash somehow.. So he is flying it around and the fin/rudder comes right off, and the plane goes in fairly soft in deep grass.I walk out and help him find it, we find the elevator way off in the field.

I held it up to him and said "Here is your problem, the fin/rudder wasn't glued on at all !"

He replies back to me... "It doesn't need to be glued on, the one on my last apprentice wasn't."
