I tend to use test--n-plug-n-play versus shrug-n-pray, Ben. You will need a crimping tool for the JST connectors, though Leon. Alternatively, if you don't want to mess around with making up your own cable, you might find it more convenient to use these (and the price is not astronomical): http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9683 (Female) http://www.hobbyking.com/hobbyking/...t_battery_pigtail_10cm_length_10pcs_bag_.html With a sharp pointy thingy (I used a dental explorer -- my dental hygienist is still wondering how it disappeared) on the male connector, you can push down on a metal barb on the crimped connectors and retract them and re-insert them swapped over so the red wire will still be the positive one. (It's the one that has the smoke in it.) You will still need some heat shrink where you solder the wires together, though. (Note to self: Put the heat shrink on the wires before you solder them together, Andy.) Hope this helps. Andy.
