It is a really nice flying plane. Yes, if there is any weakness on this plane it is the tail. One of the other members in my club had the same problem. One of the horizontal stabilizers broke in flight.

The good thing is that you can prevent it by installing flying wires. I put some on my plane and haven't had a problem. The wires are made of kevlar wire (the kind that you get in pull pull setups). I attached them with regular bolts and blind nuts
