futaba servos are under-spec'ed. mine have proven to be much stronger than the specs claim they are (vs an equal other brand servo). I personally have futaba servos on my N7's because they were already on them when I bought them. all my other helis have OMG servos on them. talk about strong, and fast, the OMG servos are arguably the strongest servo on the market per their specs. I have 0 complaints with OMG, they have be great servos, and I have never had a failure.
