Howdy, I've got the 7-channel Flysight: http://www.amazon.com/gp/product/B00LGCYHWI/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 I've got my transmitter on the equivalent of channel 4. When I put the screen in diversity mode, it only ever selects the right antenna and the image is clear. When I put it in RX1 mode I get only static. When I put it RX2 everything looks great. So it appears that RX1 is busted...this seems unlikely but I don't know what else could be the problem. I've tried cycling through all channels on RX1 and they're all static. Any ideas? Or time for a replacement from Amazon?
