If you change the RTH alt does the battery home indicator change such as if you increase it from 60m to 200m or 500m, does the timer of how long it needs before it has to come back w/ no battery change?

I know the home indicator may be based upon the current load because when I drop from high-alt the bar is changing rapidly and the home time indicator starts to drop fast.  Of course, I would never RTH to 500M but if you mess up w/ low battery by losing connection, your drone will run out of juice and crash?

Yes it will

It will

Is it even accurate though?

I believe it is

At least on my MA, the RTH altitude doesn't seem to matter.  For example, I fly up to 50 feet and reset the RTH to where the drone is.  Then I fly around  a bit and hit RTH.  The drone will get to the same GPS location and then execute an automatic landing.  It will not go to 50 feet and stay, it will go all the way down and land on the ground.

There's no way I'm overextending a flight no matter what.. well maybe so it matters to know.  I have 3 batteries so when it drops to say 40% I head back.  This way just incase something is going room I have extra room to prepare.
