JR 9100S 180oz/in @ .06 second transit time
JR 9100T 370oz/in @ .15 second transit time
So far I havent found any servo that compares to the JR 9000 or 9100 series servos. It also depends on application of course, for buggy these will be perfect, maybe overkill, so you may want to get a higher MAH RX pack.
I am going to be trying the Futaba brushless servos out for my touring car, as I feel that any faster than .10 second transit speed in that application will hurt my driving, whereas in the 8th scale buggy, I love the JR, but find that .10 second transit speed is a good sacrifice for twitchiness and control.
