The SG-90 is one of the most popular 9 gram servos available, being sold with many different labels. This is the genuine digital version of the original analog SG90. With 25cm servo wire and JR/UNI connector.

For full servo specifications, please refer to the specification tab above. A list of similar servos is also shown, where available, and is based on torque values only. All of our servos include standard manufacturers fittings.

Please note, as we buy our servos in bulk, many of the analogue Hitec servos are shipped to us packed like this, individual servos may therefore arrive loose-packed. Please do not grab and rotate servo arms by hand – this is not good for the gears and with todays light-weight servos can easily strip gears. A servo tester is a worthwhile investment.
