I have had my phantom vision 2 plus for a few weeks now and really enjoy it. However I am scared to us it to its full potential (with me piloting anyway) because sometimes it just takes off. My neighbor has two of these unites and neither of them fly like mine. Sometimes it works fine for a few minutes then it wants to go, and the battle is on, resulting is a few fairly hard landings. Sometimes it goes a few feet or a couple hundred feet and then comes back to the spot that I last had control if I don't touch anything, other times its like the Energizer Bunny and keeps going until I lose signal then it enters the "go home" mode and comes back. I have no idea what is causing this and any advice would be greatly appreciated. Very Frustrated!!
