Default No real electrical issues. Is a BEC still adviced?

So yes. I do not really have any electrical issues, even if i am running dual motors and a heavy servo.
But i do have a CC Pro BEC which i bought couple of monts ago and it is just collecting dust here......

Does it still have an advantage if i install it? Also i do only have one option left on the receiver (just a basic Axial AR-2 receiver) and they do advice to use both connections.

Hang on to it you might need it at some point. Theres a reason why most competition orientated RC rock crawlers use BECs. Running pushed to the max thirsty motors and steering servos on 3-4S eventual you'll notice your steering is not get it's full electrical requirements met. Thats when you'll wire it direct from the battery to your servo insuring that the steering servo never gets starved.

I think you can plug it into your bind port, and remove the +wire from your ESC connector,(the part that plugs into the receiver).

Then everything that was being powered by the receiver voltage via the ESC is now being fed from the lipo.
