What's this? (ESC Questions..)

Ok, but I don't fully understand the red wire situation, do I connect the red wire to the other wires?

Also, is it possible to connect an RX battery pack to the receiver?

You could use an RX battery pack, but in electric vehicles it makes more sense to use a BEC (at least IMO). They are smaller, lighter, and you don't have to worry about another battery to charge/monitor. Plus the voltage will be consistent, whereas an RX battery pack will drop in voltage as it's discharged.

EDIT: As I already posted, there is no internal BEC on this ESC. I don't think you have to remove the red wire from the RX cable.

Nope. Just remove it's connector from the ESC's reciever plug and tape it to the other wires to keep it out of the way. You could use shrink tube if you want. By removing the red wire you are preventing the external BEC and the ESC's onboard BEC from interfering with each other. The ESC recieves power from it's onboard BEC, and the radio system/servos recieve power from the external BEC.

Thanks guys. An RX Battery pack is just plug and play, right?

So long as its nimh/nicad, yeah, just plugs into the aux/batt slot on the rx. If you use a lipo rx pack, then you'll need an LVC of some sort.

Does this esc have a programming card? If so then the red wire on the signal harness is used to power the "brains" of the esc when programming.

Since it does not have an internal bec I would not worry about it.

What is the difference between Sbec and ubec?

The "S" and "U".

Seriously, they mean the same thing. S would stand for switching, while U stands for ultra or something like that.
