Heliproz sells the rubber feet that you need to buy to hold the batteries. [link=http://www4.mailordercentral.com/heliproz/prodinfo.asp?number=101714]Here[/link] is the link for it. Then you need 2 7.2v 1500ma batteries to power your starter. Once you get the stuff you will have to solder some quick connectors onto all the wires so that they can be dis-connected for charging.

I love having my starter cord free. makes it so much easier to work with when your not tethered to your flight box.
