This is very cool that you can program the button for things like that. We only have the one button but you could create multiple profiles with different options on the aux buttons and just use the profile that has the function you need for that flight. I wish the video was in English. I'm sure people are going to figure out programming the controller more and more as time passes. We may see GPS on and off with the Aux button in the future.Desværre på tysk tale.
