External Ubec?

Hi all, 

I.m buildin a Skywalker with APM 2.6 + GPS, and I have a Hobbywing Flyfun 60a Esc with built-in bec (3A-5V). In the specifications says that it can manage up to 5 servos.

I will have 4 servos on the plane, but in some forums it is recommended to use an external ubec for the servos.

What do you think is best? Built-in Bec or External UBEC?

    I always use a separate ubec for servos. If you're using 4s that specific esc overheats badly because the bec component is not switching.
