The U-BEC is an external circuit that taps power from your battery pack and regulates the voltage to the necessary 5 volts to power your receiver and servos. It does not replace the speed control. However, it replaces the BEC function in a speed control with much more capabilities. The needs for a U-Bec are necessary when the speed controller does not have an onboard BEC or when the servo count will exceed the ESC's capability. Installation is simple, just simply solder the leads to the input side of the Speed Controller at the battery connector. Then simply plug the output lead plugs into the receiver.
If using this UBEC with a Speed Controller that contains a onboard BEC, simply disable the BEC by pulling the red pin out of the servo lead on the speed control.
