I have my RTH set at 30 meters. However, I would like to change it and I can not figure out how to do so.

I am using a Phantom 3 Professional, thank you in advance.

In the app ...in camera view
click on the icon next to the Home icon in the upper left (MC Settings)
Click on Advanced Settings
Click on Failsafe Mode
Enter desired height
Note .. this is in metres (not feet)  and you have to have your Phantom connected and turned on because it's saved in the Phantom. not the app.

Please follow the suggestion above . You can find the settings via this way : "MC Settings=>Advanced Settings=>Failsafe Mode=>Failsafe Settings" .
