>>Hi Bob
A satellite reciever will give you more reliable communication over larger ranges if you are using the Radian for what it was designed for. Which is high altitude thermal soaring.
But for general mid range flight it is not really necessary.
The battery selection is up to you. The recommended 3S 1300 lipo will be more that adequate for normal flight, you can however increase that to 1800 or even 2200 to increase flight times. But just make sure you can fit the battery into the aircraft before you buy them.
Hope this helps.

Hi, Gazz. the problem with the battery is simply giving it to fit my 1800 battery will fit sort of, but have trouble closing the lid. When I come down the field this weekend I'll see if anybody has a 1500 battery that I can try in it?, I was asking about the dual receivers because most of the Radian PRO on YouTube Centre have them/
kind regards, Bob.
PS. Not a problem using my post.
