Comments: I replaced the Hi-Tec servos that came with the helo and they are quicker and more precise. Just make sure that you set the Tx frame rate to 11 Ms to get full advantage of the digital properties. Also, you can't beat the price.

Comments: So far so good. Noisy as hell but faster and more precise for servos in the price range. In contrast I have had Hobbyking servos dead on arrival.
