I just recently got the G-RX6
Range tests at home, locking my tx in a metal case and taking the rx downstairs and outside seems as good as all other Frsky rx's and the Vario seems pretty responsive straight out the box. I also left it running for 25mins on a 2s lipo and it only drifted 1.2m
I'm super impressed with the size and weight. If only I had a plane anymore to put them in haha.
