I HAVE (!) read of others breaking in servos. Read it right here in the jets forum. I think that "breaking in" is not the correct term though. The intent is to thouroughly bench TEST the new equipment, finding the occasional bad apple before you lose a 10K airplane to a 100 dollar servo with a bad gear!

The above link is to an interesting looking toy that will test servos on the bench and aid in setup too.
