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.
