How to Setup RTL in Pixhawk 2.4.8 Copter 3.6

Hi experts, needing your help on this please. How can I set up RTL in my mission planner for my F450 drone using Pixhawk 2.4.8 with 2200mah battery. Also, do I need to set height limit? First timer on this. Thanks much.

Why not read the Wiki 1st. Google “Arducopter RTL”

You mention a battery so maybe you want to know about a battery failsafe with RTL? Try Google “Arducopter battery failsafe”:
