I assumed you had already squashed the ends with a pair of pliers when you called earlier, but if you hadnt, try it ;)

Bec plugs into the BATT port on the receiver, as long as its set to 6V or less your golden :)

BEC wires, yup, just solder them to the batt wires at the point they enter the bullet, then route them as you fancy :)

Sike, i wound wanna sand down the ends either... but te crimp tool sounds awesome! got a link? ;)
