9XR Troubles...

[Ultimate_Red]

So, I've ordered a quadcopter (bits etc.) but, now I need a transmitter/receiver pack. I have seen the Turnigy 9XR on HK and think it's better than the 9X. However, I don't know what battery to get or how to get the RF module. (what is one of these)

Can someone provide me some links please?

Thanks. Rhys,
