My friend had centering problems with his M8 after owning it for only a year, but it was just out of warranty. He sent it up for repair and they charged him $35. They told him that everything spec'ed out and they found nothing wrong. However, when he got it back, it worked without issue. I believe there is another older thread regarding not centering for the M8, too. My friend was kind of disappointed because we don't know anyone here that had problems with their Futaba radios not centering even ones that were 10-15 years old.
