I have now crashed each one seven times and they are still flying. These were bad crashes, with rebuilding the front of the plane and having the tail break off,and having the wing break in half. The landing gear still has a tendency to break off in a heavy landing but I have seen other much more expensive sticks (they cost twice as much) break off just the same way. Maybe I need to land gentler? That's what I bought them for, to learn how to land smoother and gentler.
