I have just got a Phantom 2 Vision plus. I have visited the DJI download page but I am not sure what I need to download to make sure that my Phantom is up to date with the firmwares. I have downloaded and installed RC Assistant and Phantom 2 Vision assistant. I have downloaded the Driver installer as well but it asks me to connect the "MC". What is "MC" ? Can anyone give me a straight forward step by step helping hand ?
