Search for "flight packs" at Tower or Horizon...

You are really better off putting your own combination together...

For instance most flight packs come with measly 600mAh or 800mAh NiCD battery packs for the RX and servos... no where near enough for a full day at the field for me...

So it is much better to purchase what you need individually... though if you are setting up something like a simple trainer, flight packs may be an easy way in.
