I once tried using some TP 5010's and found them to be quite coarse and jerky in their movement, plus there are much better quality budget priced servos available such as Savox or Solar. Not because a servos costs less that the usual big name brands means that it is no good, as I remember when Hitec just hit the market hardly anyone was in a rush to use their stuff. Reminds me of when Honda first came out and look at them now.
