Very cool! Welcome to SparkPilots! I'm just to the north of you, I live south of Xenia. Be careful flying on the bike path, at least up hear the bike paths are part of Five River's Metro Parks and they require a permit to fly on their property which includes the bike path. I found this out the hard way when I was filming my son's Longboard race that was in Miamisburg, OH. I don't know if it's the same down there though.
This is where I go for the Five Rivers Metroparks, not sure if that's is their jurisdiction down there or not, it may be similar though. Special Permits | Five Rivers MetroParks
I think I figured out that you have to manually check for the DJI app update from within the app. I kept going to Google Play and it wasnt showing a new version.
