Run a BEC just for the steering servo for Big Rock?

[Straykiwi]

Hello Everyone.

I have a Big rock. its freaking rad.

I purchased a sweet new HV steering servo, and a MMX esc for it.

Then found out that if i run the MMX with the BEC at 7.4v i'll blow the diff brain servos...

So, my question is,

"Is there a way i can run the steering servo at 7.4v and the diff brain servos at 6v?"

really interested in all ideas!!

thanks for all your help.

Yes. But you will need an external bec.
As shown in the diagram you connect the red and black(power and ground) from the servo right to the bec, then run the signal wire to the receiver.
