I use the OrangeRX T6 and orangeRX R620 receiver in a few models, and the Turnigy TGY-i6 with Turnigy iA6 receiver in others. Should anything happen with the oranges, I'm swapping everything over to the Turnigy. I like their failsafe recovery and their menu system a lot more than OrangeRX/Spektrum/JR.
