I just figured the BX had a pretty good single RX on board that would do the job nicely for a helicopter.
I've been flying with Ar6100e's in my 450 size beginner cheapies.
It is fine without the satellite on small helicopters with little carbon fiber, but for a CF frame or larger helicopter, I think the satellite is necessary.
The reason it's expensive is quality. Some people appreciate the value of that and some people don't, but it can make a big difference. If you have experience, the cheap stuff can work, but it can often be frustrating for beginners. If you crash because your controller freaked out or something, it can cost you money. So, I prefer to have high quality electronics so that my thumbs are the weak point in the system, not my equipment.
