Sorry to hear of your loss, I was lucky with mine and noticed the increased dihedral induced on one wing when doing a turn into wind, even then it did not dawn on me that the wing tube was suspect, well you know the story, but for others I will repeat it, a friend of mine was standing astride the fus in front of the elevators whilst I started the engine, once started he lifted his leg to release the plane and proptly kicked the top of the rudder off, Oh flip I said, when we de-rigged the plane I noticed a grey line around the wing tube which upon flexing opened into a crack, with minimal effort the wing tube broke in half, so my friend had damaged and saved my plane in one go., the replacement wing tube is much thicker and stronger.
