Please make sure that the duty cycle of the controller you used is confirmed to our specifications. Otherwise, the servo can't turn up to a claimed degree.

 

Important Notes

  • Please make sure to avoid locked-rotor when using a servo, the locked-rotor will cause an internal current increase to more than 7 times as well as the temperature, the servo may burn out.

  • Connect GND is necessary.

  • Recommend to use lithium polymer battery with high rate discharge(min 5C), please don't use the dry battery.

  • Please use a short and thick power cord, don't use the Dupont cord.

  • Not compatible for Redcat thunder drift RC car, not compatible for 1/16 scale car.

Strong and responsive

These are awesome servo for the prices. What surprise me is , I found that replacing my robot with just one of these , the steering response is much faster than before. everything is okay now. If they do have any problem, l'll update!

Quiet and strong servo

Outstanding performance. Due to my miss operation they stuttered. I thought they were bad and then ask for help. They worked the problem out, and it turns out that my power supply did not give needed voltage. Now they works well.. satisfied.
