Spirit System

Please can someone explain how I can reliably save changes I make in the android app? For instance, if I set sub-trim for a servo, how do I save it to the Unit. If I change servo reversing, how do I save it to the Unit. Unlike the PC app, in the Android app there is not a Backup tab (that I can find anyway) where I can save to to the Unit.

Thanks,
Ray

You have to tap at the Menu icon in the top right corner and there press Save Settings.
Nothing else is needed before disconnecting battery.
