I also had trouble running with the new version at the new default 640x480@30. But once I set it back to 640x480@15 where I had it before it seemed to work as well as before. Then I got the bright idea of going to 320x240@15 and it works even better. I never had solid FPV beyond about 4000' but now have had it out to about 7000'. And I can never go back to living with the 3300' bug. So 1.0.39 is fine with me. Can't wait to get the better repeater on the new machine!
