the only thing i can put it down to is loose linkages i was not going fast it was on idle doing a slow pass it just flapped like a bird then snapped the tail plane in half...

my friend also has a hype also haflutter on the same day but his never broke he brought it in and checked it over and his linkages were loose he tightened them and hasn't had flutter again but he has only flown his twice...

so we will find out on sunday
