I just plugged in my Phantom Vision +. It auto updated to the newest software. Hopefully that is ok. :| Question 1, I have my RTH altitude set to 100ft in the Vision assistant 3.6 software. In the Vision app, there is a Current RTH Altitude. Is that only active once the phantom is up in the air? If I try to change it, I get a error message stating "Set Altitude Failed". Is that because I have it set in the Vision Assistant software? Is there any other way to change it without plugging it in to the computer? Question 2, Is 100ft a good height? Question 3, For the new firmware for the batteries, I take it, I have to run that for both of my batteries? Any help will be greatly appreciated.
