here is a pic, the ubec is on the side of my reciever box. You wire it to the battery connectors, the nother that has the plug for the reciever, obviously goes into the receiver.
Ok, bad pic..to small...one sec

this is with my 9920, but is the same as setting up the Qaurk. When using a UBEC or an RX pack, that replaces the bec in the controller. So when you use an rx pack, or the ubec, THEN you pull the red wire.
