The receiver pack output on the charger is designed to charge 4.8V NiMH/NiCd packs. Just plug it in and away you go!
If you were to use a 6V NiMH/NiCd pack (5 * 1.2V), you would need a different charger. The transmitter output of a standard charger would work with some care.
See the topic "Charging batteries" in this section for more info...

I'd say the easiest and best way is to use one of these.

Get a 2 channel one, that'll do two relays for you. Plus they failsafe, so it's a lot better and safer to get one of these if you're going to enter your robot into competitions. Plus they work our cheaper in the long run. By the time you add up 2 switches, a servo and a failsafe, these are the way to go. Plus if you should ever want to upgrade to bigger motors, just chuck in some bigger relays, and it'll work.

Yeah, thats pretty much it. you have two relays plug into this box. And you plug the box into your reciever. When your transmitter stick is central, both the relays are closed, and no power goes to the motor. When the stick is forward, one relay will open, and the motor will spin one way. When you move the stick back, this relay will close, and the other will open, making the motor spin the opposite way.
Much easier, and more reliable than using a servo and microswitches. Plus it failsafes. But still worth saving for a proper speedo if you can get it (if you're using drill motors that is, WW motors will be fine using this)
