I thought that the firmware 1.2.6 was a previous version and the newer version was 1.2.8. Apparently the .6 is for the Professional and the .8 is for the Advanced. But they are probably under the hood the same messed up firmware. I upgraded my Advanced to 1.2.8 and now I'm seeing strange things I have not seen before. Like video corruption on the FPV screen. And I did a night recording last night and it was blurry. Maybe someone can tell me if that's normal or not. I've done low light and it's fairly clear but not blurry like this. Now I'm waiting on the next firmware release. Please come soon!!
