For what its worth, I think that the 8411 is simply the best all round servo. Yes, there have been failures here and there, but for the no. of people i see that are happy with them, versus the no. of people that are not, it really is the only servo that I would cconsider for a giant scale. beleive me, I researched alot of options, and in the end, the only one that I was happy with, was the 8411. I even gave up my Futaba brand loyalty, which says ALOT!
