How many servos off one BEC?

[Josh_Br]

Is it ok to run three high torque servos off one BEC? The three servos are for front and rear steering, and a servo winch. The BEC is a CC at 6v, and I run 2s LiPo. The steering servos are Savox, and the winch is a Losi servo. I have a second BEC I can run if needed, but wasn't sure if it was necessary.

Thanks,
Josh

Depends on the amp draw/torque rating of the servos as well as how you have them hooked up. Is this the 10A CC BEC or the 20A CC BEC (I'm guessing the 10A).
I would NOT run 3 300+inoz servos off a single 10A CC BEC.
You could run the steering servo off the CC BEC, then run the winch & rear steer off the RX using the BEC in the ESC.

We need more info before giving a better answer.

Thanks Charlie. Yes, both BECs I have are 10A. The front steering servo is 300+ oz/in, the rear is 200+ oz/in, and the winch is 100+ oz/in. Nothing is using the ESC BEC at the moment, and I currently have the front servo and the servo winch running off one CC BEC. I haven't added the rear steer yet, but should be soon.

Should I plan on running the front steering servo off of one CC BEC, then the rear steering servo and the servo winch off the second CC BEC?

Thanks,
Josh

Since the rear servo is "sometimes used", I would try to just let the ESC/RX power the winch & rear steer.
The winch is likely used with no/low drive motor loads, thus not much power needed.

Leave the current external BEC to run the front steering, that's the best way.
If you start getting RX "brownouts", then look to split loads up a bit.

On my Class 3 scaler I run 2 BEC's, one set at 7 volts for the front servo which is a Hitec 7950, and the other set at 6 volts, the voltage limit for my 5955 winch and 7955 rear steer servo.

Thanks guys
