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.
