Downtrodden,
You are most likely right. I don't think I will have the problem he did. We have 3 other members with the 150 and they fly the pants off of them. He also said that the LE and TE of his broken stabalizer were very soft. He said he could easily put his thumb nail in them. I checked mine and it is definitely hard balsa and not soft. I think he may have got one where they messed up and used the wrong balsa. Probably a Monday or Friday plane if they even get days off over there.

I'll keep an eye on it and if I need to I'll reinforce it.
Thanks for the reply,
Gibbs
