I now have the LT back together with the smaller engine but do not really have a cure for the stab falling off and had not heard others with a similar problem. I am reinforcing the front of the stab since it drops slightly into the fus at that point. Other suggestions welcomed. This is my first kit and I spent so much time on it that I fell in love with it. wrong thing to do with a trainer. I just finished the Armidillo, coroplast and all, and it took no time at all and I am more than ready to risk it in the learning process and I suspect it is a whole lot more durable when its flight path intersects mother earth.
