How to Use UBEC
When you mount more devices to FC, because the regulator on ESC can't supply enough power for all the
devices, you need a third part 5V UBEC to supply power.
For example, if you use a Camera Mount like CM130-TPS, the servos of the camera mount require an UBEC
which can supply at least 3A current.
