I am just changing my monitor from an ipad mini 4 t a Crystalsky Ultra. As I have already installed V 4.3.32 on the ipad and the CS only takes V 4.3.16 obviously I am going back a version. Is there anything installed on the drone (MPP) I need to worry about (i.e. does the go4 app install anything to the drone other than firmware) or do I just connect the CS, update it and let it do it's thing?
