When Magnum's chain broke first year,it wasn't at the top of hill. It was only about 40 feet up or so. And it wasn't replaced. It was just bad links and they were repaired and it was running two days after it broke. So,I'm sure they didn't replace it this time either,as Brandon stated.
I think Magnum got a new chain this year,I believe.If not it was last year for its birthday.
