Note:
Please be sure to avoid locked-rotor when using servo, locked-rotor means that artificially or machine obstructs the servo to rotate normally, the locked-rotor will lead to internal current increased to more than 7 times and the temperature increases, servo will burn out.

Notice for use:
1. It's recommended that use lithium polymer battery with high rate discharge(min 5C), please don't use dry battery.
2. Please use a short and thick power cord, don't use Dupont cord
