i was running JR9100S and apparently the speed are the same according to manufacturer specs.

but this hitec 7940 is noticeably slower compared to both the JR9100S and 7950 torque.

do i have a bad batch of servo from hitec or something???

what should i do? im a little disappointed considering i spent good money on the servo.

p/s: running the speed ones on throttle and torque on steering with 2s lipo
Are you running them on 7.4 volts? These are high voltage servos. I've got the same ones, and the manufacturer's high speed specs are reflected at over 7.2 volts.
