Receiver packs

[BrianG]

Well, a battery pack probably has a higher pulse current rating than most UBECs.

The advantage to a UBEC is size, weight, and less stuff to charge.

Unless the ESC you are going to use doesn't have a BEC or has a way to disable the BEC (like the black jumper on a BK Warrior), you need to remove the red wire. This includes the Quark and MM. No other programming is necessary.
