2 ESC BEC question

I just picked up a used super with 2 Quarks and a CC BEC. I am trying to go thru the wiring so I can try and understand what is going on. When I received it, all 3 wires (pos, neg, signal) from both ESC's where being used (each into its own channel) and the BEC is not using the signal wire. I guess that is where I am confused. With the ESC's using the middle power wire, aren't I providing double power to the receiver?

Hope that makes sense.
 
But since you have removed the middle wire, you may want to consider removing both and run your servo's at 6V. It gives the servo more juice, thus more torque and speed.

The down side is that you need to have either a seperate reciever battery pack or a voltage regulator.
 
I could be wrong but I think those ESC's have a power switch for the BEC. Turn the switch off turn the red wire off make sense? Possibly one esc's bec is switched off while the other is in the on position.

However, I would remove both red wires from the esc's and use the BEC to power the reciever. But, I think you already knew that.

It could also be wired for servo isolation, however if you don't see a bunch of hack wiring or Y-harnesses chances are thats not how it's wired.

Bec's all ways only use just the red and black. They are a power source nothing more. I think the CC was done with 3 to allow the Castle link to respond to it.

Mster, the switch for each ESC does control the power wire. But the switch on my Mamba was the same way, I thought.

Well, the wiring job is a mess. I took it all apart yesterday but drew up a diagram on paper. The signal wire from the BEC was never used. There is a Y harness to connect both servos red and black wires to the BEC, while each servos signal wire went to the receiver (each to a different channel).

I guess I am just really confused about why the power wires from each of the Quarks was still in. I think that if I pull the power wire from each Quark and try it, I should not hurt anything if it does not work. Does that seem correct?

The rig runs 2 JR8711 servos. When on a steep climb, the rears will no steer. Should they be able to with the CC BEC? I have never owned a super before, so this is a whole new experience to me.
 
He has the servo power isolated with the y harness. The bec's on the esc's has to be hooked up to power the rx because the external bec is only powering the servos. You can run 6 esc's together without removing the red wire as long as the esc's are the same model.
 
Is there a wiring diagram for the castle bec with 2 esc? i also read that it could just be plugged in one of the extra ports on a receiver and the current could flow through the receiver and feed the servos? sorry for asking again but it gets confusing, you should see the wire mess in one of my clods with an mpi regulator.
