Hi,
I think yes, you need at least for 3 reasons:

- using an external BEC helps your controller to get not hot
- that servo you are using can peak over 3.5 Ampere and this is a lot for an internal ESC Bec
- using an external bec means you will have a lot less spurious current coming from
the Esc and going to the receiver ... this usually means less interference.

Ciao,
Daniele
