hello, in step 2 of the $50 robot tutorial, it shows how to make the bot remote controlled. I`m not using a nimh pack, i`m using a battery holder. There are two wires coming out of the battery holder and I`m not sure how to connect them to the servos and to the receiver. I also read the "REMOTE CONTROL ROBOTS" page but I still can`t figure it out. Thanks in advance.
