I've had a UCD .46 powered with Saito 100 for 3 years now and have yet to come close to tearing off anything except for the landing gear about 4 times. I have not reinforce anything. This is not a high speed airplane. High speed can cause flutter and all kinds of not so nice things can happen. I fly with half power or less except when hovering or going vertical. As for the wing I've never heard of the wing exploding. so I don't know what they are referring to. Why your stab broke in flight could it have been cracked or weakened on the ground accidentally?
All I can say after 3 years and a couple hundred flights mine is still in one piece. (except for the landing gear). I can almost gaurantee you will knock it of eventually. This may not have been much help but you may have been going to fast.
