Timer failsafe and RTL+Land

I’m new on arducopter and trying to config a good battery/time failsafe.
If I select RTL on low batt, when the hexa reach the home position, will it land?
May I make manouvers while in battery failsafe RTL?

Is there a way to setup a max time flight failsafe? I mean, I would like to config a 10minute flight and then a failsafe trigger will happend.
