I have only today updated to 3.06 as I have just fitted the groundstion to my phantom(quite happily using 1.08 up till now).I upgrade my Vision a couple of weeks ago to so I could use its waypolnt function and I like the way it gives you the warning about returning to home based on where you are and how much battery you will need to get back.My question is,does the phantom 2 (non vision)throw up a similar warning,maybe through the iOSD?Or does it just automatically start to RTH when it reaches 20%,which is now the default 1st. warning value.
