Huh, last couple of months have been way too busy! It has been difficult to find spare time for FPV!
Finally I had chance to re-fit my Mobius cam with a 2" lens cable. The longer ribbon cable makes it much easier to squeeze the camera inside the canopy. Now I have placed the pcb sideways to the right hand side of the canopy so that it doesn't touch the battery or the frame and I don't need to drill any holes to push the buttons.
The most recent firmware updates have inproved white balance settings but there is still room for improvement. Colours are still off and the camera makes severe WB adjustments time by time.
