I had 2 of the 580's. the first 1 went in because the plastic standoffs for the empenage bound and locked the controls. The second lasted a long time with care. A few things to keep in mind with this plane. #1 keep airspeed down, high g's will fold it up as fast as you can blink an eye. That was the end of mine! #2 using an outrunner, a prop saver is a must the wimpy landing gear will let the prop strike the ground. Also this empenage addendum is over complicated, just put the elevator servo and horn on the other side, problem solved. As for as flying it will flat spin awesome, slow flight is stout with the big controls. It does however have terrible coupling. It hovers rock steady, oh yah and again keep the airspeed way down unless you want 90 degrees of dihedral. As stated earlier it does look pretty in the air, I have many photos that look really good.
