They might be good servos, but i say u git wut u pay for. I paid $114 for my JR Z9000T Digital servo, which is metal geared and puts out 320oz/in. of torque and has a transit time of something like 0.12 . I use one to steer my BL-Revo (only 1) with great results. Bashing and racing with it for 3 years, no problems. And trust me i run that truck hard!
