Hey All I'm a recently qualified CAA PFAF holder. I love my inspire but I've not yet upgraded the DJI App on the ipads or the batteries, RC/Transmitter or the UAV itself. There are sooo many stories on here of people failing and having problems; is the update that problematic? Also can someone please send me a link for instructions to update firmware on the batts, UAV and Transmitter? thanks in advance for advice and help! Sorrry if this goes over old ground.
