SAME DAY DESPATCH Order before 3pm Monday-Friday for same day shipping

The HS-311 is a standard sized economy servo offering fantastic performance and reliability at a very reasonable price.

Arrives in a small box with 4 mounting screws and lugs and 5 servo arms.

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.
