Yeah, I know... I generally don't like to bash other company's stuff, but that Hitec literally was the worst servo I ever had. It was SUPPOSED to be a High-speed servo with good 1/10 scale torque. It was in a XXX-BK2 that had super-free moving steering and that servo was sooooo sssslllloooowww and noisy to boot. It was noisy at neutral, noisier when it moved, it was so noisy we joked that it's chirping and screeching were an alien language. I eventually replaced it with a futaba and all was good. I put the Hitec in a rock crawler and destroyed it. Kinda fun.
Anyway, this is the Savox servo thread and I still say they are gold. very nice, very fast, and super-powerful.
