Default What voltage to set CC BEC at wth 2 srvo's

What voltage should I set my CC BEC at ? I am using 2 towerpro 995's and a 11.1 volt lipo ? I am wiring it to bypass the RX only using the signal wire from the RX. That way i'm not overloading the RX. Thanks. Bob.

they can handle up to 7.2V but i would go over 6-6.5 that way they will last longer without frying them

It fried one of mine I believe.

But I was told they only had trouble out of the older rx's.

I NEVER let a external BEC power the receiver, I let the ESC's BEC do that. I found that is best and safest.

How do you wire in a BEC then? Just a y harness with the servo with the red wire pulled out at the receiver?

That drawing is right if you want to do it that way I've always done it the way Castle says to do it. I've ran 7.2V through my BEC into Spectrum RX's with no probs....On all of my other rigs the BEC is set at 6V though. I've never had any trouble with my Castle BEC's except for the first batch when they came out. They didn't want to work with a Novak Rooster Crawler ESC to well at first. But everything has Mambas in them now
