The Servo motor is specially made for robotics with custom design. Also designed to work on 8.4V supply voltage. The motor provides massive torque of 35kg-cm. Compatible with RKI-2323, RKI-2322, RKI-2321,RKI-2320, RKI-2319, RKI-2318, RKI-2317,RKI-2316.
Operating Voltage: 6V ~ 8.4V
Operating temperature range: -10°C ~ 50°C
I bought this servo awhile back and it performs pretty well. The horn moves very smooth/quiet and produces a good amount of torque. Will look into buying more if I continue my project in the future.
