Why do you need to use UBEC?
The UBEC is a switch-mode DC regulator separated from ESC (ESC---Electronic Speed Controller for brushless motor), it will take high-voltage (5.5V-23V) power from your battery pack and convert it to a consistent safe voltage for your receiver, gyro and servos.
If you are using a speed controller with a built-in BEC, it will very likely have only a limited ability to supply power to your receive and servos without overheating. If you have a relatively high-voltage battery pack or have heavy servo loads, you should consult the ESC specifications to determine what the stated recommendations or limitations are. In general, if you are using a 4S Lithium pack, or more than a 12-cells Nickel based pack, you should consider using the UBEC. In such a case, the built-in BEC of ESC only support 2 servos, so it is not suitable for RC helicopter and big aircraft.
