FMA Quantum
I have 4 of the FMA Quantun receivers and a couple of the others on 50MHz that I fly with my JR 8103 radio. They have imprssive ground range and I have yet to have a problem in several years of flying them. I did lose a Fortress receiver, but that was after my fun fly plane had a meeting with a giant. You can guess who won that one. He only had a couple of ribs broken while I had lost radio, plane and engine. That was a really good TT .46.
