I am afraid that " built quite light " is an understatement !

On the one that I had the complete tail assembly both vertical and horizontal stab separated from the model all in one piece, taking a good part of the fuselage with it. Everybody that seen it happen and viewed it afterwards all stated that it was total " factory / design / assembly " structural failure.
